description: It is well known that thin film modules like CdTe have certain power meta instabilities depending on their short- and long-term history. For CdTe extensive dark storage (e.g. due to transportation or modules from warehouse) typically lead to a lower output power and requires extensive light stabilization prior indoor STC characterization. IEC 61215-1-2 states requirements for standard stabilization for new, out of the box CdTe modules. For single modules that might be feasible, but to verify larger batches extensive indoor light soaking is cost and time prohibitive and therefor alternative procedures to reliable determine the output power of CdTe modules is needed. However, current standards do not cover any particular stabilization for field aged modules. Pre-treatment and storage of the module play an important role in the quickly to determine output power. Short term illumination by flash-testing/measurement increases measured output power and basically compensate for short term meta stabilities. However, the final power depends on pre-history and on illumination duration and intermediate short-term dark storage. Different modes of operation (Voc, Isc and Pmpp) and different temperatures are investigated to accelerate stabilization utilizing artificial light. In general, higher temperature lead to an accelerated change of characteristic parameters of the PV module. The operation mode of the module during light soaking (Isc, Voc or Pmpp) does also influence the change behavior of the output power and to an immediate response of the module. In the last experiment “stability” was reached after approx. 30 hours of light soaking at 1.000 W/m². Therefor at least three different effects have to be considered, namely dark-storage, fast to compensate light effects (ms-range) and long-term saturation effects in the range of days.

description: The present study is focused on the design and application of simultaneous double-side illumination approach for the characterization of full- size commercial silicon bifacial module in order to reproduce the real conditions with both front and rear illumination. The testing procedure is performed by using a prototype system based on Light Emitting Diode (LED) rear bias light coupled to a large-area long-pulse solar simulator that illuminates the front side of the device. The viability of the method to fulfill the IEC TS 60904-1-2 requirements for characterization of bifacial devices is tested. “Self-reference” methodology is applied using an accredited reference values (ISO/IEC 17025) obtained by single-side illumination of the same test device. Both, the proposed approach and prototype testing system for large-scale modules have demonstrated good performance in comparison with the single-side method. The current-voltage (I-V) curves and key electrical parameters are very similar. Slightly higher Pmax (0.3-0.9%), BiFi (0.5%) and FF (0.3-0.7%) are obtained. The rear-side non-uniformity in the double-side illumination system varies with applied voltage and distances between the LED and the module, classifying the LED in Class B (>200 W/m2) or Class C (<100 W/m2). The proposed testing system configuration would be convenient and economically viable for industrial applications of bifacial modules.

Verwaltungsdigitalisierung

description: Digitalisierung in der Politik und Verwaltung wurde lange darauf reduziert, bestehende Service und Informationsangebote einfach nur online verfügbar zu machen. Mittlerweile wird vielen Personen klar, dass dieser Blick außer Acht lässt, dass die Digitalisierung zu einem fortlaufenden, tiefgreifenden Veränderungsprozess gehört: Der Digitalen Transformation unserer Demokratie. Eine erfolgreiche Digitalisierung der Verwaltung erfordert neue Prozesse, Strukturen und Kompetenzen und damit eine grundsätzliche Weiterentwicklung und Modernisierung unseres Staates. Hierin liegt eine große Chance für unsere Demokratie. Ein digitaler Staat ist mehr als nur effizienter und effektiver.Die Digitalisierung der Verwaltung birgt die riesige Chance, staatliches Handeln für Bürger:innen zugänglicher, nachvollziehbarer und partizipativer zu machen.

Diese Potenziale warten seit der weltweiten Verbreitung des Internets und neuer digitaler Dienste in den 1990er Jahren darauf ausgeschöpft zu werden. Schließlich wird seitdem über das Demokratisierungspotenzial von Vernetzung und neuen Technologien diskutiert. Viele neue Ansätze, politische Institutionen offener und partizipativer zu machen, wurden weltweit entwickelt und erprobt. Trotz der vielen wichtigen Initiativen und Pilotprojekte konnten die erhofften Potenziale bisher in der Fläche nicht umgesetzt werden. Wer das ändern möchte, muss erstmal verstehen, woran das liegt. Aus diesem Grund haben wir mit politik-digital e.V. zusammengearbeitet, um uns einen ersten Überblick über das Feld digitaler Beteiligung und seiner Verknüpfung mit Verwaltungsdigitalisierung in Deutschland zu verschaffen. Bei dem hier vorliegenden Papier handelt es sich um die pointierte Zusammenfassung der wichtigsten Erkenntnisse aus einem Workshop und Expert:innen-Interviews. Diese Ergebnisse dienen uns und jedem Interessierten zur Orientierung. Wir freuen uns über Anregungen und Feedback!

description: The Maximum Weight Independent Set (MWIS) problem on graphs with vertex weights asks for a set of pairwise nonadjacent vertices of maximum total weight. MWIS is known to be $NP$-complete in general, even under various restrictions. Let $S_{i,j,k}$ be the graph consisting of three induced paths of lengths $i, j, k$ with a common initial vertex. The complexity of the MWIS problem for $S_{1, 2, 2}$-free graphs, and for $S_{1, 1, 3}$-free graphs are open. In this paper, we show that the MWIS problem can solved in polynomial time for ($S_{1, 2, 2}$, $S_{1, 1, 3}$, co-chair)-free graphs, by analyzing the structure of the subclasses of this class of graphs. This extends some known results in the literature.

PV Module Design, Manufacture, Performance and Reliability

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 825-829
description: We are presenting the design and development of a capacitive moisture sensor and a resistive temperature sensor integrated into solar cells. The sensors are produced by screen printing on solar cell wafers using a silver paste commonly used in solar cell production. The sensor cells are designed to be integrated into PV modules. For evaluation of the sensors, measurements of imprinted wafers laminated between two layers of encapsulant were performed. Impedance measurements on the moisture sensor indicate an exponential dependency of the capacitance on the moisture content in the encapsulant at constant temperatures. The temperature sensors show a high sensitivity and reproducibility.

description: A current – voltage (I-V) curve is a graphical representation of the relationship between the voltage applied across a solar cell and the current flowing through the solar cell. Key properties of solar cells can also be extracted from the shape and details of the curve, enabling greater insight into its solar energy conversion ability and efficiency. The work focuses on the uncertain I-V curves classification from a big online database based on the current and voltage evaluation. The open-circuit voltage, short-circuit current, current and voltage at MPP on the I-V curves are derived to define the ratios according to the characteristic information of curve shapes. Then, the real I-V curves were acquired from the measurement system and used to verify the proposed method. The results show the proposed method achieved good effects of identifying the curves types and it can be used to meet data requirements of further scientific research.

PV Module Design, Manufacture, Performance and Reliability

description: For years, photovoltaic systems have been successfully installed on a large scale on open spaces as well as on (BAPV) and on buildings (BIPV). For the applications, PV modules in the classic glass-backsheet or glass-glass design are mostly used because their properties are well known. For BIPV and further on for automotive applications (VIPV) it makes sense to reduce the weight of the modules in order not to overload the building’s loadbearing capacity statics as well as for vehicles to minimize their energy consumption. One approach for weight reduction is by replacing glass with polymer materials. The light coupling on typical PV modules is largely optimized by means of an anti-reflective coating (ARC) on the front glass. This has not yet been done for polymer front sheets, but this paper will take the first step and characterize different lightweight approaches based on polymer front sheets with different solar cell types (SHJ, IBC) for their skewing behavior and then give an evaluation of the electrical yield for angle-dependent installation as well as for different locations.

description: The globular cluster 47 Tuc exhibits a complex sub-giant branch (SGB) with a faint-SGB comprising only about the 10% of the cluster mass and a bright-SGB hosting at least two distinct populations.We present a spectroscopic analysis of 62 SGB stars including 21 faint-SGB stars. We thus provide the first chemical analysis of the intriguing faint-SGB population and compare its abundances with those of the dominant populations. We have inferred abundances of Fe, representative light elements C, N, Na, and Al, α elements Mg and Si for individual stars. Oxygen has been obtained by co-adding spectra of stars on different sequences. In addition, we have analysed 12 stars along the two main RGBs of 47 Tuc. Our principal results are: (i) star-to-star variations in C/N/Na among RGB and bright-SGB stars; (ii) substantial N and Na enhancements for the minor population corresponding to the faint-SGB; (iii) no high enrichment in C+N+O for faint-SGB stars. Specifically, the C+N+O of the faint-SGB is a factor of 1.1 higher than the bright-SGB, which, considering random (+-1.3) plus systematic errors (+-0.3), means that their C+N+O is consistent within observational uncertainties. However, a small C+N+O enrichment for the faint-SGB, similar to what predicted on theoretical ground, cannot be excluded. The N and Na enrichment of the faint-SGB qualitatively agrees with this population possibly being He-enhanced, as suggested by theory. The iron abundance of the bright and faint-SGB is the same to a level of ~0.10 dex, and no other significant difference for the analysed elements has been detected.

description: Experimental correlation analysis and first-principles theory are used to probe the structure and evolution of Ag-CO-Ag single-molecule junctions, both before the formation, and after the rupture of the junctions. Two dimensional correlation histograms and conditional histograms demonstrate that prior to the single-molecule bridge configuration the CO molecule is already bound parallel to the Ag single-atom contact. This molecular precursor configuration is accompanied by the opening of additional conductance channels compared to the single-channel transport in pure Ag monoatomic junctions. To investigate the post-rupture evolution of the junction we introduce a cross-correlation analysis between the opening and the subsequent closing conductance traces. This analysis implies that the molecule is bound rigidly to the apex of one electrode, and so the same single-molecule configuration is re-established as the junction is closed. The experimental results are confirmed by ab initio simulations of the evolution of contact geometries, transmission eigenvalues and scattering wavefunctions.

description: The IEC Standard (60)904-5:1993/2011 limited the calculation of Equivalent Cell Temperature (ECT) of PV devices from the VOC to irradiance above 0.2 Sun and a constant ideality factor. Increased error at low irradiance was attributed to a varying temperature coefficient (TC) of the VOC. In previous works, we showed that this was in fact due to rise of the ideality factor (near Open Circuit, OC) at low irradiance, and developed individual corrections for different monofacial c-Si PV modules allowing for accurate ECT evaluation down to ~0.03 Sun. In the present work, we compare the ECT to module back temperatures (Tback) measured with up to 16 sensors in two outdoor testing campaigns involving 6 monofacial, glass-backsheet and 5 bifacial, glass-glass c-Si modules made with PERC cells. We present a method to derive the irradiance-dependent ideality factor, nOC, allowing for accurate ECT evaluation and outdoor performance characterization also at the very low irradiance. Correction methods for the rated VOC and its TC are presented. We show the possible uses and challenges of the ECT–Tback plots over in-plane irradiance (T plots) and propose a simple effective irradiance in the bifacial PV case.

description: Nonlinear vibrational spectroscopy profits from broadband sources emitting in the molecular fingerprint region. Yet, broadband lasers operating at wavelengths above 7 μm have been lacking, while traditional cascaded parametric frequency down-conversion schemes suffer from exceedingly low conversion efficiencies. Here we present efficient, direct frequency down-conversion of femtosecond 100-kHz, 1.03-μm pulses to the mid-infrared from 7.5 to 13.3 μm in a supercontinuum-seeded, tunable, single-stage optical parametric amplifier based on the wide-bandgap material Cd0.65Hg0.35Ga2S4. The amplifier delivers near transform-limited, few-cycle pulses with an average power > 30 mW at center wavelengths between 8.8 and 10.6 μm, at conversion efficiencies far surpassing that of optical parametric amplification followed by difference-frequency generation or intrapulse difference-frequency generation. The pulse duration at 10.6 μm is 101 fs corresponding to 2.9 optical cycles with a spectral coverage of 760–1160 cm−1. CdxHg1−xGa2S4 is an attractive alternative to LiGaS2 and BaGa4S7 in small-scale, Yb-laser-pumped, few-cycle mid-infrared optical parametric amplifiers and offers a much higher nonlinear figure of merit compared to those materials. Leveraging the inherent spatial variation of composition in CdxHg1−xGa2S4, an approach is proposed to give access to a significant fraction of the molecular fingerprint region using a single crystal at a fixed phase matching angle.
Assessment of Corporate Social Responsibility Practices From Employees' perspectives: The case of Addis Ababa Abattoirs Enterprise
Creators: name: Ruhama, Temesgen
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The study is initiated by the fact that very little is known about the current practices in Ethiopian abattoirs regarding CSR (Corporate Social Responsibility). It assesses the current CSR practices in the case origination, why the organization undertakes CSR and what challenges are confronted by the organization while undertaking CSR. In doing so, CSR is assessed based on the seven core subjects provided in the ISO 26000 (2010). These seven core subjects of CSR are organizational governance, human rights, labor practice, the environment, fair operating practices, consumer issues and community involvement. The case organization is selected because of the environmental and social concern it has, so how it acts in a socially responsible manner or not is an issue that is worth looking in to. The nature of data that is collected and analyzed is qualitative and both primary and secondary data sources were used through questionnaire and interview. It is a qualitative and descriptive case study and descriptive statistical tools were applied using SPSS to analyze the collected data. The study applied standard statistical sample size determination technique and also used mixed sampling techniques such as purposive and simple random sampling. Finally the results of the study shows that the enterprise has good CSR practices regarding organizational governance, fair operating practices and customer issues. On the other hand, the enterprise has poor CSR practices regarding human rights, labor practice, the environment and community involvement. Additionally, the enterprise mainly engages in CSR activities to gain improved financial performance, enhanced reputation, meeting regulatory requirements and growing community pressure. And challenges faced by the enterprise while implementing CSR include location, non availability of organized planning and clear CSR guidelines. Accordingly, recommendations were extended to strengthen the good practice and improve where needed through building a close relationship with its stakeholders to find and tackle challenges.

description: We propose an approach to detect individual Rydberg molecules with each molecule consisting of two atoms in different Rydberg states. The scheme exploits the movement of atoms in the presence of an external force that exerts only on atoms in one Rydberg state. Since the movement of atoms in the other Rydberg state depends on whether they are bound with atoms directly driven by the applied force, bound atoms can be distinguished from unbound atoms. By utilizing electromagnetically induced transparency, it is possible to non-destructively image the positions of molecules. The scheme is sensitive to a weak force, which is suited to optically detect spatial positions and bond structure of Rydberg molecules.

Year: 2017

description: The objective of this research is to measure the supply chain performance of pharmaceuticals manufacturing companies of Ethiopia by studying the supply chain performance of Addis pharmaceutical factory as a unit of analysis. Descriptive and quantitative methods of research were used and data were collected by interview questions, document review and questionnaires. Document review was conducted to study especially the financial performance as factual data was needed. The performance of the supply chain was measured using balanced score card model. Based on questionnaires data were collected from employees of Addis pharmaceutical factory and distributors to measure the supply performance of APF. The findings of the study suggested that financial, learning and growth and customer perspectives have statistically significant result. Generally, the study findings have suggested that the levels of supply chai performance is approximately moderate in the case of Addis pharmaceutical factory in terms of the four dimensions. It has also discovered that, among the four performance measurement dimensions financial perspective is comparatively in a better position in the company. From the survey conducted and filled by customers, It was found also that the company did not respond to customer orders, have no good communication system and the company does not conduct customer survey to evaluate customer satisfaction level. The study advocated that a lot of emphasis need to be directed to customer perspective and learning and growth perspective in order to achieve customer satisfaction and employee learning and growth through efficiency or productivity, consequently improving the organizational performance as a whole Key words: supply chain performance, Balanced score card

description: The differential decay rates of the processes $J/ψ\to p\bar{p}π^{0}$ and $J/ψ\to p\bar{p}η$ close to the $p\bar{p}$ threshold are calculated with the help of the $N\bar{N}$ optical potential. The same calculations are made for the decays of $ψ(2S)$. We use the potential which has been suggested to fit the cross sections of $N\bar{N}$ scattering together with $N\bar{N}$ and six pion production in $e^{+}e^{-}$ annihilation close to the $p\bar{p}$ threshold. The $p\bar{p}$ invariant mass spectra is in agreement with the available experimental data. The anisotropy of the angular distributions, which appears due to the tensor forces in the $N\bar{N}$ interaction, is predicted close to the $p\bar{p}$ threshold. This anisotropy is large enough to be investigated experimentally. Such measurements would allow one to check the accuracy of the model of $N\bar{N}$ interaction.

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 811-813
description: Building integrated photovoltaics (BIPV) offers efficient utilisation of land area and local renewable energy generation. Attractive aesthetic aspects and efficient energy generation are important drivers for market acceptance of solar panels as building elements. Coloured modules improve aesthetic aspects at the expense of efficiency loss and increased cost. For a given lightness and colour, a minimum energy loss due to reflected photons is unavoidable. Additional efficiency loss may come from parasitic absorption in the colour providing layers and from unwanted reflection and absorption in the nonvisible near infrared wavelength range. In this paper we present a novel method to identify the different loss contributions: visible reflection loss, near infrared reflection loss, and parasitic absorption loss. The methodology is applied to silicon solar cells where colouration is introduced by interference from a thin indium tin oxide layer on top of the SiNx:H antireflection coating. The method presented here will be a useful tool to optimize efficient colouring of solar cells.

description: The photoelectron momentum shifts along the laser propagation are investigated by the time-dependent perturbation theory for diatomic molecules, such as H$_2^+$, N$_2$ and O$_2$. Such longitudinal momentum shifts characterize the photon momentum sharing in atoms and molecules, and oscillate with respect to photon energies, presenting the double-slit interference structure. The atomic and molecular contributions are disentangled analytically, which gives intuitive picture how the double-slit interference structure is formed. Calculation results show the longitudinal photoelectron momentum distribution depends on the internuclear distance, molecular orientation and photon energy. The current laser technology is ready to approve these theoretical predictions.

description: Potential-Induced Degradation (PID) is a major reliability problem and can lead to significant power and energy yield losses and even total loss of the affected systems. If a PV module is operated under PID conditions, in short, if there is a high voltage drop between the solar cells installed in the module and the front glass, which is in contact with the grounded frame, PID may occur. Electric fields in the magnitude of MV/cm through the glass, encapsulation and the dielectric passivation layers of the solar cell cause a leakage current. Ions or electrons flow to the cell and can lead to severe degradation. PID is almost independent of the cell technology and affects different generations of solar cells. The approach presented here shields the dielectrics of the Si solar cell from electric fields and interrupts the leakage current. The proposed concept can be applied to different cell technologies.

description: Albedo is one of the crucial variables in the energy estimation for bifacial photovoltaic modules due to the modules’ capability to collect electricity from both front- and rear-sides. There are several modeling tools for energy estimation of these modules. However, all of them use a constant albedo value for all period. Our paper reports on the impact of using real measured values of albedo in the modeling process. The results show that there is a difference of up to 7% when the value of the albedo set constant instead using a real measured value. This result translates into an inaccurate prediction affecting the making-decision process for stakeholders in the adoption of this technology.

description: High voltage (HV) photovoltaic (PV) systems are affected by potential induced degradation (PID). PID decreases the output power of PV modules, however, it is a reversible process and could be recovered. Researchers demonstrated that the earlier PID is detected, the higher and faster the recovery. This work presents the experimental results comparing the PID recovery of PV modules under early and late PID detection. It was shown that complete recovery is possible if PID is detected at an early stage (< 1% power loss).

ALACT
academic skills

description: Modern Developments in Pharmaceutical Sciences (MDPhar) is taught to 50-60 second-year Pharmaceutical Sciences (Phar) bachelor students at the Vrije Universiteit Amsterdam, the Netherlands. The course lasts four weeks and is situated at the end of the academic year. Students work on a project in randomly assigned groups of three students, and various activities are included to promote skill development. To enhance reflection on skill development, the ALACT model was implemented in the course. All reflection questions are shown in the context of the different ALACT cycles during the MDPhar course and the associated ALACT phases. For each cycle, the students are asked to answer the reflection questions of that cycle.
description: The reflection questions presented here are a translation of the original Dutch version that was used in the MDPhar course.
On the number of Waring decompositions for a generic polynomial vector

description: We prove that a general polynomial vector $(f_1, f_2, f_3)$ in three homogeneous variables of degrees $(3,3,4)$ has a unique Waring decomposition of rank 7. This is the first new case we are aware, and likely the last one, after five examples known since 19th century and the binary case. We prove that there are no identifiable cases among pairs $(f_1, f_2)$ in three homogeneous variables of degree $(a, a+1)$, unless $a=2$, and we give a lower bound on the number of decompositions. The new example was discovered with Numerical Algebraic Geometry, while its proof needs Nonabelian Apolarity.

description: This work aims at supporting a better understanding of the LeTID phenomenon. It relies on accelerated stress test under current injection to emulate light exposure for three batches of bifacial PV modules (mono and cast mono silicon modules). Indoor characterization is carried out regularly at different irradiance levels and electrical parameters are estimated from it. The paper goes through a qualitative analysis describing the evolution of electrical characteristics and a quantitative one relying on descriptive statistics to identify the drivers behind the LeTID degradation, their role during degradation and regeneration phase and the unbalanced response to different irradiance levels. The analysis reports that a convergence of the long-term stabilization power regardless of the injected current and highlights that the performance losses are driven globally by Isc, then Voc and FF. Isc has a prominent role in the degradation phase and FF drives the power recovery for the regeneration phase. In addition, LeTID phenomenon appears significantly stronger at low irradiance levels for the rear face. The maximal degradation is reduced by 0.2%/(100W/m²) between 200 W/m² and 1200 W/m².

description: We investigate a 2,000-year genetic transect through Scandinavia spanning the Iron Age to the present, based on 48 new and 249 published ancient genomes and genotypes from 16,638 modern individuals. We find regional variation in the timing and magnitude of gene flow from three sources: the eastern Baltic, the British-Irish Isles, and southern Europe. British-Irish ancestry was widespread in Scandinavia from the Viking period, whereas eastern Baltic ancestry is more localized to Gotland and central Sweden. In some regions, a drop in current levels of external ancestry suggests that ancient immigrants contributed proportionately less to the modern Scandinavian gene pool than indicated by the ancestry of genomes from the Viking and Medieval periods. Finally, we show that a north-south genetic cline that characterizes modern Scandinavians is mainly due to the differential levels of Uralic ancestry and that this cline existed in the Viking Age and possibly earlier.

description: This work aims to understand the nature of the vibration experienced by the PV modules during transportation over 800 kms on two different types of containers. The methodology used for the analysis of transportation vibration data generated during PV module transportation is reviewed. Transportation vibration data was collected from 5 PV module pallets placed in two containers, one with a metal floor and another one with a wooden floor. It is shown that signal-triggered data sampling result in less loss of information compared to time-triggered data sampling. It was found that the PV modules placed in the container with wooden floor showed lower amount of damage as compared to the PV modules in the container with metal floor. The vibration along the axis perpendicular to the PV module plane was severe in the 10-20 Hz range.
