Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 4245-4250
description: The relation of the PV generator to the inverter is of great importance in the system design of grid-connected photovoltaic
systems. This sizing ratio decides whether power peaks and the contained energy can be fed into the grid. Too small inverter
sizes will lead to peak power losses by regulating the inverter power down by increasing the operating voltage. If the maximum
operating input voltage is reached it can also cause shutdowns. This increases sizing losses. This paper investigates the
behavior of the different subsystems of the PV power plant in Rothenburg (Saxony, Germany) towards its peak power regulation.
An analysis of high resolution measurements (10.000 channels stored every second) is presented. Different sizing ratios
are demonstrated to result in different loss ratios. It was possible to see yield losses due to peak power regulation. The biggest
power regulations were detected in the 1 MVA class at a sizing ratio of 94.8 %. In the 2 MVA class only small power regulations
were detected in June at a sizing ratio of 89.5 %.

description: This paper investigated the effect of hydrogen content and substrate temperature on the properties of
the hydrogen-doped ZnO films deposited by RF magnetron sputtering for thin film solar cells application. The
hydrogen incorporation into the film improved the stability and crystal quality and conductivity remarkably. All the
films show a very high transmittance at the range from 200 nm to 2000 nm.The films deposited at room temperature
with a hydrogen flow of 4.5 sccm show the best electrical property and stability.

description: We study spectral properties of the self-affine measure $μ_{M,\mathcal {D}}$ generated by an expanding integer matrix $M\in M_n(\mathbb{Z})$ and a consecutive collinear digit set $\mathcal {D}=\{0,1,\dots,q-1\}v$ where $v\in \mathbb{Z}^n\setminus\{0\}$ and $q\ge 2$ is an integer. Some sufficient conditions for $μ_{M,\mathcal {D}}$ to be a spectral measure or to have infinitely many orthogonal exponentials are given. Moreover, for some special cases, we can obtain a necessary and sufficient condition on the spectrality of $μ_{M,\mathcal {D}}$. Our study generalizes the one dimensional results proved by Dai, {\it et al.} (\cite{Dai-He-Lai_2013, Dai-He-Lau_2014}).

description: The diffusion of phosphorus mediated by phosphorus oxychloride (POCl3) is extensively used in
photovoltaics due to its higher controllability over phosphine. However, the POCl3 decomposition in the gas phase as
well as the subsequent oxidation reaction between silicon and the resulting phosphorus oxide are not very well
documented and increase the complexity of a realistic simulation of the POCl3 diffusion. This paper examines the
possibility of modeling the POCl3 diffusion only by modifying the diffusion constants of a standard phosphine
mediated diffusion simulation implemented in Sentaurus process. To this aim, the Boltzmann-Mattano Analysis
(BMA) is applied to experimental SIMS profiles in order to extract a concentration dependent effective phosphorus
diffusivity. The fitting of diffusivity profiles is then performed to determine the specific diffusion constants of the
diffusion mechanisms believed to be responsible for the phosphorus diffusion in silicon. Through the study of
specific artifacts appearing in the diffusivity profile because of the non ideal conditions for application of the BMA, it
is believed that at low POCl3 flow, the surface concentration during the pre-deposition phase is low enough to induce
an enhanced diffusivity at the early stage of the diffusion. Finally, the assumptions of this diffusivity fitting are
reviewed and a model matching these assumptions is identified in Sentaurus Process for a direct implementation of
the BMA results into Sentaurus Process.
title: One year caring: A longitudinal, narrative study on men’s perspectives of caring for a female partner with cancer
Creators: name: Young, Jenny
Publisher: name: Edinburgh Napier University
Year: 2022

description: Background
In Scotland and countries such as the US and Canada, 4 in 10 family carers are men. Yet in the main, increasing evidence on the extent of men’s involvement in care has not transferred to the research literature around men’s experiences. In particular, there is a significant lack of qualitative research that explores men’s perspectives of masculinity and the social structures and discourses that shape it.

Aim
To explore the perspectives of men who are caring for a partner with a cancer diagnosis in Scotland.

Method
Eight men participated in narrative interviews. Seven were interviewed three times over the course of one year and one further participant was interviewed once. Participants were aged from 32-76 years old, were all White British and in heterosexual relationships. The study included a range of cancer types. Interviews were transcribed and analysed after each interview and also longitudinally, using a structural and performance approach to narrative analysis. The overarching theoretical framework was social constructionism.

Findings
Data analysis was written into eight individual stories and four scenes. Those scenes are: ‘In that moment life changes’; ‘Caring but not a carer’; ‘Opening the valve’ and ‘Repercussions’. The men drew on different discourses of masculinity in order to frame caring in masculine terms. At times this evoked feelings of fragmentation and conflict, particularly over the manipulation of emotions. By concealing feelings such as worry, fear and loneliness to their partner, they were fulfilling expected norms that position men as being stoical and invulnerable. Yet, this was often done as an act of love and protection rather than due to a discursive need to be the ‘strong’ one.

Conclusion
To my knowledge, this is the first longitudinal, narrative study to explore the experience s of caring for a partner with cancer from the perspective of men. I have identified a new depth of understanding as to why men in caring roles may report feelings of strain. Acknowledging the limitations of the study design, in terms of transferability and representation of the study findings, different relationships (for example, same-sex or other family member) will have particular dynamics and consequences for how the role is experienced. Nevertheless, the findings from this study have interrelated implications for research, policy and practice. I recommend that this work is used to spark further action on carer identification and engagement with men who are less likely to identify with the role; yet would benefit from a range of different supportive interventions.
title: Trauma and psychosis: synthesising evidence, network modelling and expanding into an interventionist-causal paradigm to investigate mediating mechanisms
Creators: name: Woodrow, Amanda
Publisher: name: Edinburgh Napier University
Year: 2022

description: The link between childhood trauma and the development of psychosis in adulthood is already well established, but factors which explain this relationship are currently less well understood. This thesis firstly aims to review the current state of evidence, then contribute novel empirical findings to help expand the understanding of how early traumatic experience leads to the development of psychosis. Information about causal factors is essential to the future development of effective therapeutic interventions for psychosis.

Firstly an extensive systematic review of studies which examines potential mediating mechanisms between trauma and psychosis is undertaken. Data from 37 studies were used to analyse 232 mediation models, taking into account the magnitude and significance of effects, along with study quality. Judgements are offered on the strongest areas of evidence, and implications for future research are discussed.

The first empirical study uses network analysis to generate a data-driven model of trauma, sub-clinical psychotic experiences and other relevant factors using data gathered from an online survey in a general population sample. Exploratory analyses were undertaken to derive a hypothetical model, which was then analysed statistically using structural equation modelling. The model hypothesis was pre-registered then prospectively tested in a second sample of data. Results and implications are discussed in the context of psychological models of psychosis.

The second empirical study uses an interventionist-causal paradigm to conduct a randomised controlled trial in a clinical psychosis population with experience of paranoia. An emotion regulation skills intervention was tested against an active control condition, with participants providing pre- and post- data, along with experience sampling data collected using mobile phones for analysis of individual and group change. Although limited by small sample size, findings are discussed in terms of acceptability, feasibility and implications for research and practice.

description: In the present work, we have investigated high-efficiency flexible CIGS thin film solar cells on titanium (Ti)
and polyimide (PI) foils. In case of CIGS/Ti devices, 120nm-thick CBD-ZnS(O,OH) buffer layers were deposited onto CIGS
thin films. The conventional CBD-CdS buffer layers were used for CIGS/PI devices. The influence of the substrate
temperature during CIGS deposition on film properties and cell performance has been mainly investigated by scanning
electron microscopy (SEM), X-ray diffraction (XRD), and secondary ion mass spectroscopy (SIMS) analyses. CIGS thin
films were deposited by the three-stage process at substrate temperatures of 460-550ºC. A desirable double grading of
Ga/(In+Ga) atomic ratio required to achieve high efficiency devices was formed at substrate temperatures of 500ºC and
480ºC for devices on Ti and PI foils, respectively. By optimizing cell fabrication conditions, the total area efficiencies of
17.9% and 15.7% were achieved for flexible CIGS solar cells on Ti and PI foil substrates.

Silicon Solar Cell Characterisation and Modelling

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 1474-1477
description: Hetero-junction with intrinsic amorphous thin-film (HIT) solar cells has been confirmed to
achieve 23% by Sanyo Electric. From the theoretical viewpoint, how to further enhance the
efficiencies of the silicon solar cells for the next generation is a most critical issue. We are the first
to propose the novel solar cell structure of amorphous/crystal heterojunction with front- and
back-doping into silicon substrate in order to resolve the carriers transport between heter-jounction.
We simulated with various boron doping profiles into front-side silicon wafers based on new
proposed structures. The doping densities of both p- and n-a-Si were kept at 1019 cm-3 in this
simulation. With higher boron density, Voc and Jsc only slightly vary but F.F. increase more.
Therefore, the efficiency can increase due to reduce recombination over interfaces. The insertion of
doping profile into silicon really improve the hole carrier transport problems on i-a-Si/c-Si interface.
The efficiency can increase due to reduce recombination over interfaces.
We further investigated how the rear-side doping density inside silicon affected the
efficiencies of HIT solar cells. We don’t observe the enhancement of efficiencies in HIT with
phosphorous junction-depth. We speculated the results reflected advantages of i-a-Si/c-Si interfaces.
Very few interface states demonstrated great reaction with dangling bonds after i-a-Si deposition on
c-Si. The conduction-band differences at i-a-Si/c-Si don’t play an important role limiting the
electron carrier transport. Therefore, we don’t need any BSF layer if the great properties i-a-Si can
be deposited on c-Si. We expect experiments of delicate shallow doping profile may be achieved by
thermal diffusion, or plasma doping or ion-implanting techniques in the future.
title: Guidelines for artificial intelligence-driven enterprise compliance management systems

Publisher: name: Edinburgh Napier University

description: The use of Artificial Intelligence (AI) to design and drive a Compliance Management System (CMS) at an enterprise level is a strategic decision to be taken by large organizations. Given the complexity this decision entails, conceptual guidelines addressed to senior management and board of directors are required. The original contribution to knowledge and practice of this research lies in the understanding of how compliance management systems are set-up in organizations, by using the CMS framework derived from literature, later confirmed by empirical data. Furthermore, this research originally contributes to both knowledge and practice, through the depiction of the enablers and barriers of AI adoption in organizations, as well as the recommended conceptual guidelines for AI-driven CMSs. Using three case studies as a research method, this paper investigates the current set-up of CMSs, as well as the enablers and barriers of AI adoption and then discusses the driving themes of strategic importance to organizations when sourcing AI aimed at supporting the management of compliance. These themes are: CMS components structures responsibilities, enablers and barriers of AI, control and compliance of AI applications, compliance by design, data governance and data management, cyber security, information technology infrastructure, regulation and regulators, and collaboration with external parties. The thematic findings of this research are additionally discussed in the context of the three lines of defence of an enterprise (business units, support functions, audit functions), making this an organizational framework for the design of an AI-driven CMS. The research concludes with the recommendations that in order to adopt an AI-driven enterprise CMS, organizations should do the following: strategically decide the type of AI organization they want to be, involve stakeholders in the design phase of new policies and AI applications, invest in data governance and IT infrastructure, tap on best practices from cyber security, and collaborate with external parties and regulators.
Measurement of the inclusive $t\bar{t}$ production cross section in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV and determination of the top quark pole mass

description: The inclusive cross section of top quark-antiquark pairs produced in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV is measured in the lepton$+$jets and dilepton decay channels. The data sample corresponds to 9.7 fb${}^{-1}$ of integrated luminosity recorded with the D0 detector during Run II of the Fermilab Tevatron Collider. Employing multivariate analysis techniques we measure the cross section in the two decay channels and we perform a combined cross section measurement. For a top quark mass of 172.5 GeV, we measure a combined inclusive top quark-antiquark pair production cross section of $σ_{t\bar{t}} = 7.26 \pm 0.13\,(\mathrm{stat.})\,^{+0.57}_{-0.50}\,(\mathrm{syst.})$ pb which is consistent with standard model predictions. We also perform a likelihood fit to the measured and predicted top quark mass dependence of the inclusive cross section, which yields a measurement of the pole mass of the top quark. The extracted value is $m_t = 172.8 \pm 1.1\,(\mathrm{theo.})\,^{+3.3}_{-3.1}\,(\mathrm{exp.})$ GeV.

title: The role of social media marketing in organisational business development in the construction industry: Managerial perspectives
Creators: name: Tan, Jianwen
Publisher: name: Edinburgh Napier University
Year: 2022

description: The growth in social media use as a marketing tool continues to gain popularity among businesses in different sectors. Due to social media marketing, business-to-business relationships and the creation of networks in the market have proved to be attractive to the construction industry despite overreliance on the traditional marketing approaches. Despite its popularity, research regarding the social media marketing role in organisational business development is limited.

This thesis explored the perception of managers in the construction industry on the role of social media marketing in organisational business development. With a focus on three large construction companies in Singapore, given the need to obtain an in-depth understanding of the managerial perspectives on social media marketing, a qualitative interpretivist approach has been adopted. The study involved 12 respondents in senior positions in the construction industry who were interviewed using a semi-structured interview technique and their responses analyzed using thematic analysis to answer the research questions.

The review of literature, as well as the analysis of the information obtained from respondents, resulted in invaluable insights that added to the body of knowledge in social media marketing in organisational business development. The reviewed literature resulted in the creation of a theoretical framework that informs the exploration of the social media marketing role in organisational business development. Further, the results of the study show that social media marketing plays an important role in organisational business development among construction firms. As part of the contribution of this study, a set of model guidelines has been developed that shows the approaches that marketers can use to enhance the positive influence of social media marketing in organisational business development. The influence of social media marketing on marketing functions and its positive performance outcomes are also key contributions to the organisational business development among construction firms. The study has recommended the need to improve resource commitments to enhance social media marketing as an important contributor to organisational business development among the construction firms, increase involvement in social media marketing, and improve reliance on multiple social media marketing platforms to enhance positive influence on organisational business development. The findings from this study can guide the use and tailoring of social media marketing in organisational business development within the construction industry.
title: Leveraging information and communication technologies (ICTs) for enhanced marketing performance: Key issues for marketers in Island-Nation’s commercial banks
Creators: name: Savary-Torres, Tracey Gail
Publisher: name: Edinburgh Napier University
Year: 2022

description: Unprecedented strides have been made in technological advancements within recent decades. The synergistic effect of information technologies with communications technologies -coined information and communications technologies (ICTs)- has been pervasive, inspiring much academic enquiry. In the field of marketing, research has burgeoned in its prominent nexuses with ICT, for example electronic commerce, digital marketing, and customer relationship management (CRM). Academics concentrated on adoption determinants and the impact of technologies on consumers, firms, and countries. However, few studies examined this phenomenon from the perspective of the marketer - the implementer within the firm. Further, despite signaling ICTs’ centrality in marketing practice and its capacity to transform the discipline, scholars have also flagged possible reluctance to technology uptake by marketers. Accordingly, this research sought to contribute towards bridging the lacuna by exploring the scope of ICTs being used by marketers in practice, the impact on performance, and challenges encountered. The study also has an explanatory component seeking underlying reasons for technology adoption.

The investigation employed a qualitative multi-method research design with a critical realism underpinning, supported by online questionnaires and semi-structured interviews. It is one of few studies drawing upon a combination of traditional and relationship marketing theory, as opposed to technology adoption theory, to undertake research on ICT adoption and usage in marketing. The findings revealed a selection of customer-facing and non-customer-facing ICTs being used by marketers including analytical, monitoring, collaboration, and other ICT tools. Underlying reasons for adoption spanned environmental, technological, and organisational factors, including strategy. The study’s main contribution to knowledge was highlighting the need to consider the impact of change when contemplating ICT adoption. A conceptual framework linking major themes in the literature was developed in this regard. Further, a framework for incorporating ICTs into marketing was also designed to assist marketers in their practice.

description: The ASPIN solar cell simulator has been developing for many years now, initially developed for onedimensional
(1D) analysis of amorphous silicon solar cells, it has now matured into a two-dimensional (2D)
simulator ASPIN2 with the user interface, capable of simulating any kind of heterojunction solar cells.
A combination of 1D and 2D simulations is essential for a detailed investigation of thin-film polycrystalline
CIGSS solar cells, in particular where spatial inhomogeneities affect their performance. The results of 1D
simulations show the average output parameters of solar cell, while the results of 2D simulations point to deviations
of these parameters, which arise due to diverse shape and electronic activity of GBs inside the active layer, when the
parameters are compared to those of 1D simulations.
The results of 1D simulation of thin-film polycrystalline CIGSS solar cell indicate that the influence of GBs is
the most detrimental when these are placed within space charge region (SCR) and/or close to the heterointerface.
The simulations in 2D confirm that the output performance of the solar cell depends primarily on the relative volume
fraction and electronic activity of GBs within the SCR regardless of their shape. The electronic activity at the GBs
must be as low as possible to ensure a high efficiency of CIGSS solar cells.

description: In this paper, we study the memory properties of transformations of linear processes. Dittmann and Granger (2002) studied the polynomial transformations of Gaussian FARIMA(0,d,0) processes by applying the orthonormality of the Hermite polynomials under the measure for the standard normal distribution. Nevertheless, the orthogonality does not hold for transformations of non-Gaussian linear processes. Instead, we use the decomposition developed by Ho and Hsing (1996, 1997) to study the memory properties of nonlinear transformations of linear processes, which include the FARIMA(p,d,q) processes, and obtain consistent results as in the Gaussian case. In particular, for stationary processes, the transformations of short-memory time series still have short-memory and the transformation of long-memory time series may have different weaker memory parameters which depend on the power rank of the transformation. On the other hand, the memory properties of transformations of non-stationary time series may not depend on the power ranks of the transformations. This study has application in econometrics and financial data analysis when the time series observations have non-Gaussian heavy tails. As an example, the memory properties of call option processes at different strike prices are discussed in details.

description: David Lindsay (1876-1945) wrote the metaphysical fantasy novel, A Voyage to Arcturus (1920), six further novels, and a typescript of philosophical notes (National Library of Scotland). Lindsay had a lifelong preoccupation with what he called the Sublime, drawing on Schopenhauer and German romanticism. Using the medium of experimental documentary film, I investigate Lindsay’s ideas and imagery and their analogue with filmmaking, such as his use of non-diegetic sound to indicate the sublime in his novels, and an unpublished 1928 notebook in which he started to adapt his novel The Haunted Woman (1922) for cinema. My film A Vast Shadow House: David Lindsay’s Vision sets extracts from Lindsay’s writing with new experimental landscape footage, together with interviews with contemporary Lindsay experts and admirers to investigate Lindsay’s vision. The film and this thesis situate Lindsay in the cultural context of romanticism, symbolism, occultism, and modernism. Drawing on aspects of cinematic theory (Schrader 2018 [1972]), I reframe Lindsay’s concern with the ineffable using narrative withholding techniques, ironic narration, and extended duration. I invoke Chion on sound in film, particularly the oneiric power of non-diegetic voices. The project examines Lindsay’s potential for cinematic meaning in the 21st century, finding analogues with filmmakers such as Tarkovsky, Herzog, Gröning, Kiarostami, and Gee.

description: B-doped multicrystalline silicon ingot was intentionally co-doped with 100 ppmw iron to investigate the
behavior of iron and other metal impurities after phosphorus diffusion at different temperatures as a function of distance
from the surface, ICP-MS was utilized due to its precise measurement capability and low detection limits for the most
metal impurities in silicon. Neighboring wafers were used to evaluate the initial and after phosphorus diffusion impurity
contents. Iron contents at the wafer surface exceeds 500 ppmw within the vicinity of 0 ~0.007 m due to the surface
contamination during slicing, etching and handling process. The iron total contents after gettering does not seem to be
redistributed with high contents accumulated in the diffused layer. One possibility is the diffuse of iron impurities toward
the silicate glass layer.

description: We consider adaptive change of diet of a predator population that switches its feeding between two prey populations. We develop a novel 1 fast--3 slow dynamical system to describe the dynamics of the three populations amidst continuous but rapid evolution of the predator's diet choice. The two extremes at which the predator's diet is composed solely of one prey correspond to two branches of the three-branch critical manifold of the fast--slow system. By calculating the points at which there is a fast transition between these two feeding choices (i.e., branches of the critical manifold), we prove that the system has a two-parameter family of periodic orbits for sufficiently large separation of the time scales between the evolutionary and ecological dynamics. Using numerical simulations, we show that these periodic orbits exist, and that their phase difference and oscillation patterns persist, when ecological and evolutionary interactions occur on comparable time scales. Our model also exhibits periodic orbits that agree qualitatively with oscillation patterns observed in experimental studies of the coupling between rapid evolution and ecological interactions.

description: Aluminum-doped zinc oxide are a representative for a transparent and conducting oxide thin film
(TCO) and is commonly used as front contact in chalcopyrite and amorphous/microcrystalline silicon solar cells.
Optimum optical and electrical properties for this application are obtained for moderate doping levels and high
mobilities. State-of-the-art films, preferably deposited by magnetron sputtering or low pressure chemical vapor
deposition, exhibit mobilities around 40 cm2/Vs. Post-deposition thermal treatment will usually lead to a strong
increase of resistivity. If the films are capped by thin silicon layers, however, the degradation of electrical properties
can be prevented and a significant increase in mobility can be obtained. The highest mobility reached in this study is
67 cm2/Vs.

description: Let $P, Q\in \mathbb{F}_q[X]\setminus\{0\}$ be two coprime polynomials over the finite field $\mathbb{F}_q$ with $\operatorname{deg}{P} > \operatorname{deg}{Q}$. We represent each polynomial $w$ over $\mathbb{F}_q$ by \[w=\sum_{i=0}^k\frac{s_i}{Q}{\left(\frac{P}{Q}\right)}^i\] using a rational base $P/Q$ and digits $s_i\in\mathbb{F}_q[X]$ satisfying $\operatorname{deg}{s_i} < \operatorname{deg}{P}$. Digit expansions of this type are also defined for formal Laurent series over $\mathbb{F}_q$. We prove uniqueness and automatic properties of these expansions. Although the $ω$-language of the possible digit strings is not regular, we are able to characterize the digit expansions of algebraic elements. In particular, we give a version of Christol's Theorem by showing that the digit string of the digit expansion of a formal Laurent series is automatic if and only if the series is algebraic over $\mathbb{F}_q[X]$. Finally, we study relations between digit expansions of formal Laurent series and a finite fields version of Mahler's $3/2$-problem.

description: Die Frage, welche Folgen der regelmäßige Kontakt wikingerzeitlicher Skandinavier mit der byzantinischen Hochkultur im Norden hatte und welche Rolle byzantinische Einflüsse in den Transformationsprozessen jener Epoche spielten, ist bis heute weitgehend unbeantwortet. Der Aufsatz unternimmt den Versuch, den bisher bekannten Bereichen, in denen es Indizien für derartige Transferprozesse gibt (Christianisierung, materielle Kultur, künstlerische Stilmittel), einen weiteren hinzuzufügen: das geographische Wissen. Anhand der Untersuchung derjenigen Namen für Orte und Gruppen im östlichen Mittelmeer, die im wikingerzeitlichen skandinavischen Quellenmaterial vorhanden sind, werden die Übernahme und Adaption griechischer Begriffe und byzantinischer Semantiken herausgearbeitet. Dabei zeigt sich, dass die Skandinavier zwar einen byzantinischen Blick für das Detail entwickelten, aber keine byzantinische Perspektive einnahmen.
description: The question which consequences the regular contacts between Viking Age Scandinavians and the Byzantine civilization had and the role Byzantine influences may have played in the transformation processes of this period, remains to date largely unanswered. This paper tries to add a new field of Byzantine-Scandinavian transfer to those already known (e.g. Christianization, material culture, art style), i.e. geographical knowledge. By analyzing those names of places and groups in the Eastern Mediterranean which are present in the Scandinavian source material dating from the Viking Age, the adoption and adaptation of Greek terms und Byzantine semantics can be traced. The evidence shows that the Scandinavians did indeed develop a Byzantine gaze on details, but failed to assume a Byzantine perspective.

description: Changes to approval criteria and QA/QC (combination of quality assurance) standards are sensitive issues to statistical data producers because the production of new national statistical data must be approved by the Office of National Statistics. Concerns about implementing AI and/or big data technology into national statistical data have been on the rise internationally. In other words, rapid changes to approval criteria for national statistical data are occurring in real-time. However, despite signs of institutional change, a stark contrast in methodology and evaluation standards between AI/big data technology and current statistical techniques indicates some form of resistance in actual implementation. As such, this report introduces the matters mentioned above and actual application cases abroad and explicitly analyzes technological issues of implementing AI technology into national statistical data production, ultimately unearthing elements needed to accelerate the adoption of institutional policy change. Two determinants were identified as necessary for stimulating the implementation of AI and big data technology into national statistical data based on implications deduced from anticipated issues.

description: The Art Collection of the Faculty of Fine Arts of the University of Porto (FBAUP) mainly consists of works created in class by young artists during their learning and educational period. These works are collected primarily to provide a learning and teaching tool for fine arts students. In its formation and development, the collection has undergone significant changes. Some of these changes were caused by the affiliation of the collection to the first public art museum in Portugal, the Museu Portuense de Pinturas e estampas, created in 1833. When the Academia Portuense de Belas Artes was founded in 1836, both the museum and the academy were placed under the responsibility of the same director. Additionally, the collection suffered from the effect of national education reforms to teaching and learning methods, which influenced students’ art works and the development of the collection. However, the original purpose of constituting the art collection remains the support of fine art education and training. Throughout the last decade, our strategy has focused on the co-ordination of museum activities with the teaching and research goals of the Faculty of Fine Arts in particular and of the university in general. It has also focused on its future role as a place dedicated to cultural and artistic knowledge more closely connected with society at large. This paper concentrates on the teaching and research projects that have been developed since the official constitution of the Fine Arts Museum of the University of Porto in 1996.

description: Optimization of p-type hydrogenated microcrystalline silicon oxide thin films (p-µc-Si1-xOx:H) by RFPECVD
13.56 MHz method for use as a p-layer of hetero-junction µc-Si:H solar cells was performed. The properties of
p-µc-Si1-xOx:H films were characterized by conductivity, activation energy, Raman scattering spectroscopy, and
spectroscopic ellipsometry. The wide-gap p-µc-Si1-xOx:H were optimized by CO2/SiH4 ratio and H2/SiH4 dilution effect.
Besides, we also investigated effects of wide-gap p-µc-Si1-xOx:H layer on the performance of hetero-junction µc-Si:H
solar cells with various optical band gap of p-layer. We observed that a wide-gap p-µc-Si1-xOx:H is effective to improve
the open circuit voltage of the solar cells. These results indicate that wide-gap p-µc-Si1-xOx:H is promising for use as
window layer in hetero-junction µc-Si:H solar cells.

description: The photovoltaic industry considerably increased in the last years. Thin film technologies have grown
at an even more significant rate than conventional silicon solar technologies. A market share of about 20 % for thin
film solar modules is forecasted for the year 2020 and worldwide measures to increase the production capacities of
photovoltaic manufacturers are recognized. Besides the increasing implementation of photovoltaic’s on the market it
is strongly important not to lose sight of possible end-of-life strategies for used PV modules, like take back systems
and recycling options. Due to the long life expectancy, today’s returns of used PV modules are relatively low, but it is
expected that there will be a significant increase from the year 2020. PV manufacturers already identified the need for
research on further treatment options of used PV modules and to develop technology specific recycling processes.
Based on advanced recycling procedures, most materials used in PV modules can be returned on the market as
valuable materials, or in case of plastics, energetically recovered. Regarding thin film technologies, the recycling of
used modules could also provide an additional source of rare metals like tellurium or indium to satisfy the increasing
demand of these materials on the market. For ecological purposes, the recycling of modules can furthermore
contribute to a reduction of the environmental profile of the whole module life cycle. Using the method of Life Cycle
Assessment (LCA), these environmental benefits due to the recycling of PV modules can be quantified.
At Chair of Building Physics (LBP) a Life Cycle Assessment study was carried out to evaluate the
environmental profile of the recycling of CdTe modules. Based on latest industry data, the study presents LCA result
of an already applied recycling process of CdTe solar modules. Within this study a detailed LCA model of the
recycling is built up including the processing of used modules, the recycling and energy recovery of materials as well
as the further treatment and disposal of solid and liquid wastes. The study showed that the recycling of materials
would contribute to a significant reduction of the environmental profile of end-of-life of CdTe modules. In total, the
recycling of outgoing materials would reduce the Primary Energy demand in the End-of-Life from 81 MJ/m² to
-12MJ/m² (reduction from around -93MJ/m²) and in terms of the Global Warming Potential from 6kg CO2-equiv./m²
to -2,5 CO2-equiv./m² (reduction from around -8,5 kg CO2-equiv./m²).
The paper gives an overview on the approach of the study, discusses the main outcomes and analyses the significance
of recycling in relation to the environmental profile of the production and total life cycle of CdTe modules.

description: An important issue for the crystalline Si wafer based PV industry is the performance of the cells over a life
span of 25 to 30 years. The present paper discusses the main sources of degradation with focus on the diffusion of
elements in a wafer over a 30-year period, which may result in semiconductor device degradation. Some experimental
results of accelerated tests are presented. It has been shown that the variations of the performance of solar cells as
manufactured vary considerably, and that a large statistical sample is necessary in order to obtain good conclusions from
such experiments.

description: Among the many process gases that are needed in solar cell manufacturing, this work focuses on the
specialty chemicals used as boron sources for zinc oxide (ZnO) layers grown by CVD doping. From a literature
survey, promising alternative boron sources with the best matching technical and economical requirements were
selected. Four different boron compounds from three different chemical families were identified: trimethylborate,
triisopropylborate, catecholborane and 1,3,5-trimethylborazine. The compounds characterizations were carried out
with a thermogravimetric analyzer (TGA), to assess the thermal stability of the compounds, their boiling points and
their volatility. Only catecholborane shows thermal behavior not suitable for CVD application. The three others are
volatile and stable at the delivery temperature. Final validation was obtained by growing by MOCVD and
characterizing boron doped ZnO layers from the selected precursors. High boron incorporation have been achieved
mainly with 1,3,5-trimethyborazine. Compared to standard ZnO:B layer grown with diborane, similar layer
characteristics have been obtained with this precursor.
