description: Diamond wire sawing method has become a standard for sawing mono c-Si bricks. There are established criteria based on parameters like total thickness variation and saw mark depth for acceptance of the sawn wafers. Based on such criteria as specified in the wafer datasheets, the wafers are classified as A grade, B grade and unqualified. However, variations in the sawing process that can still possibly classify the wafers as good wafers could adversely influence the cell production parameters. In this work, we report the observations from an integrated factory relating the quality of manufactured wafers on PERC solar cell production parameters as compared to the standard wafer quality parameters. It is observed that wafers with non-uniform saw damage can lead to decrease in the A+/A grade cells by up to 6% relative due to increase in the B grade and unqualified cells. In addition, the breakage rate was also observed to be more than 500% higher compared to the standard production. The observations point to the need to adjust the wafer inspection system criteria to minimize such wafers being classified as A grade and optimization of the sawing process to reduce the non-uniform sawing.

description: Cloud computing has become the ubiquitous computing and storage paradigm. It is also attractive for scientists, because they do not have to care any more for their own IT infrastructure, but can outsource it to a Cloud Service Provider of their choice. However, for the case of High-Performance Computing (HPC) in a cloud, as it is needed in simulations or for Big Data analysis, things are getting more intricate, because HPC codes must stay highly efficient, even when executed by many virtual cores (vCPUs). Older clouds or new standard clouds can fulfil this only under special precautions, which are given in this article. The results can be extrapolated to other cloud OSes than OpenStack and to other codes than OpenFOAM, which were used as examples.

description: Statistical language models are central to many applications that use semantics. Recurrent Neural Networks (RNN) are known to produce state of the art results for language modelling, outperforming their traditional n-gram counterparts in many cases. To generate a probability distribution across a vocabulary, these models require a softmax output layer that linearly increases in size with the size of the vocabulary. Large vocabularies need a commensurately large softmax layer and training them on typical laptops/PCs requires significant time and machine resources. In this paper we present a new technique for implementing RNN based large vocabulary language models that substantially speeds up computation while optimally using the limited memory resources. Our technique, while building on the notion of factorizing the output layer by having multiple output layers, improves on the earlier work by substantially optimizing on the individual output layer size and also eliminating the need for a multistep prediction process.

description: In this work, the contact resistivity between fire through metal contacts and boron implanted n-type textured silicon wafer with various doping profiles is studied. The metal contacts are screen printed on boron emitter passivated with l2O3/SiNx stack and subsequently underwent a fast-firing process by a conveyor belt furnace. Electrochemical capacitance-voltage (ECV) measurements show that increasing the activation temperature and time results in a decrease in dopant peak concentration and a deeper junction. The contact resistivity has generally shown a decreasing trend in TLM results as the activation temperature and duration increase due to the increasing junction depth. The sample activated at 1050 for 60 minutes shows a slight increase in contact resistivity which may be caused by decreased surface doping concentration. The lowest contact resistivity is measured as 1.4 m. cm2 for the emitter activated at 1050 for 30 minutes.

description: 38th European Photovoltaic Solar Energy Conference and Exhibition; 271-273
description: In this study, we develop a POCl3 diffusion recipe so that we obtain a thicker phosphosilicate glass layer for laser doping. The formation of a laser doped selective emitter is achieved by utilizing an industrial-type picosecond pulsed laser operating at 532 nm (green) wavelength () and pulse repetition rate (frep) of 1 MHz. To demonstrate the selective emitter concept, sheet resistance reduction of the laser processed region after tube furnace diffusion is provided. In addition, produced samples are metalized and the difference of contact resistivities of both homogenous emitter and laser doped emitter is shown. By applying a moderate amount of heat accumulation on the surface, specific contact resistivity of the laser doped region is reduced to around 3 mΩ.cm2. We report process details and results in this paper.

description: Effective supply chain management practices has become a potentially valuable way of securing competitive advantage through customer satisfaction since competition is no longer between organizations, but among supply chains. This research used three dimensions of SCM practice (collaboration, information sharing and logistics design) tests the effect of SCM practices on customer satisfaction. The data for the study was collected from 68 employees of Ethiopian Sugar Corporation. In addition, interview with department team leaders was done and a questionnaire also has been distributed for 50 customers for supporting data .The relationships proposed in the framework were tested using Pearson correlation, and the causal relations were analysed using regression analysis. From the result of the analysis it is concluded that there is strong relationship between each SCM practices (Collaboration, Information sharing and Logistics design) and customer satisfaction. Therefore, in order to achieve advancement in marketing and financial performance in the long-run through enhancing customer satisfaction, it is better for the organization to give due emphasis to the constructs of those SCM practices

description: Scaling relations describing the electromagnetic behaviour of coated conductors (CCs) greatly simplify the design of REBCO-based devices. The performance of REBCO CCs is strongly influenced by fabrication route, conductor architecture and materials, and these parameters vary from one manufacturer to the others. In the present work we have examined the critical surface for the current density, Jc(T,B,$θ$), of coated conductors from six different manufacturers: American Superconductor Co. (US), Bruker HTS GmbH (Germany), Fujikura Ltd. (Japan), SuNAM Co. Ltd. (Korea), SuperOx ZAO (Russia) and SuperPower Inc. (US). Electrical transport and magnetic measurements were performed at temperatures between 4.2 K and 77 K and in magnetic field up to 19 T. Experiments were conducted at three different orientations of the field with respect to the crystallographic c-axis of the REBCO layer, $θ$ = 0$°$, 45$°$ and 90$°$, in order to probe the angular anisotropy of Jc. In spite of the large variability of CCs performance, we show here that field and temperature dependences of Jc at a given angle can be reproduced over wide ranges using a scaling relation based only on three parameters. Furthermore, we present and validate a new approach combining magnetic and transport measurements for the determination of the scaling parameters with minimal experimental effort.

description: Phosphorus doped emitter surfaces have been widely passivated by PECVD deposited silicon nitride (SiNx) layers which also act as anti-reflection coating (ARC). However, the following high temperature processes applied in the regular p-based cell fabrication sequences might result in significant degradation in open circuit voltage (Voc) values. In this study, an additional heat treatment called as low temperature annealing (LTA) process after SiNx deposition is applied to improve implied open circuit voltage (iVoc) values of symmetrical p-type samples with symmetrically diffused emitter. Around 15 mV increase in iVoc is obtained with the optimized LTA process conditions for symmetrical samples. We also demonstrate the effect of LTA process on solar cell performance by approximately 10 mV gain in open circuit voltage and approximately 0.5%abs gain in cell efficiency

description: Crystalline Silicon (c-Si) remains a dominant photovoltaics material in solar cell industry. Currently, scientific and technological advances make possible of producing the c-Si solar cells (SCs) efficiency close to the fundamental limit. Therefore, combining the experimental results with modeling becomes crucial to further improve the efficiency and reducing the photovoltaics systems cost. We carried out the experimental characterization of the highly-efficient textured c-Si SCs and compared the results with the analytical modeling formalism [1] and a preliminary modeling, using the commercial solar cell simulation software [2]. The analytical model accounts for all recombination mechanisms, including nonradiative exciton recombination and recombination in the space-charge region (SCR). To compare the theoretical results with the experiment, we proposed empirical formula for the external quantum efficiency (EQE), which describes its experimental spectral dependence near the absorption edge. The approach used allows a comparative modeling of the short-circuit current and photoconversion efficiency in the textured crystalline silicon solar cells. The theoretical results, both from analytical formalism and computational tools, compared to the experimental measurements, allowed: (i) Validating the formalism developed, which was then used to optimize the key parameters of the SCs, such as the base thickness, doping level and others. (ii) We demonstrated several advantages of the application of our analytical formalism, compared to the computational software tools.

description: Silicon nanowires (Si-NWs) have been able to draw huge attention in solar cell research particularly for their inherent and unique characteristics of light confinement. Here, we have reported correlated absorption depth profile, electromagnetic field distribution and exciton generation rate distributions for different diameters of the vertically aligned Si-NWs (coverage, ca. 6.5×108/cm2 with diameter 50-200 nm) at different spectral wavelengths. Although Si-NWs were observed to be different in size and shape in experiment investigations, for simplicity, a single Si-NW of cylindrical shape was modeled and optimized to correlate the aforementioned characteristics. Light absorption and energy flow distribution confirmed that Si-NW facilitates to confine photon absorption of several orders of enhancement whereas the energy flow is also distributed along the wire itself. On the other hand, electric field distributions and excitons generation distributions highlighted the higher probability of strongest sites compared to those of flat silicon wafer.

description: We describe a generic scheme to extract critical exponents of quantum lattice models from sequences of numerical data which is for example relevant for non-perturbative linked-cluster expansions (NLCEs) or non-pertubative variants of continuous unitary transformations (CUTs). The fundamental idea behind our approach is a reformulation of the numerical data sequences as a series expansion in a pseudo parameter. This allows to utilize standard series expansion extrapolation techniques to extract critical properties like critical points and critical exponents. The approach is illustrated for the deconfinement transition of the antiferromagmetic spin 1/2 Heisenberg chain.

description: Understanding solar cell performance and stability under field-relevant operation conditions is of paramount importance for long lasting solar energy generation. Diverse forms of degradation can occur during solar cell exposure to high temperatures and illumination. These can originate from bulk-related degradation mechanisms caused by interactions of impurities within the silicon crystal, or from changes at the dielectric or metallic interfaces, resulting in surface-related degradation. In this work, we report on the application of in-situ temperature- and illumination-controlled Suns-VOC measurement analysis for a range of commercial cells of different architectures undergoing boron-oxygen (BO) defect stability testing using a newly developed Suns-VOC elite tester capable of extended light-soaking on four industrial size solar cells simultaneously at elevated temperature. It is shown that room temperature current-voltage measurements and those extracted via in-situ Suns-VOC are in excellent agreement with each other giving precise values within ± 1 mV variation. Similarly, the extracted minority carrier density dependent lifetime data using the quasi-steady-state VOC method by the elite tool is compared to that of the one measured by the photo-conductance decay method using lifetime structures yielding to effective values of ±5 μs of precision. It is also demonstrated that the application of a BO-related light induced degradation mitigation processes on finished cells as well as unmetallized precursors improves their VOC, avoids degradation, and can be thoroughly characterized using this new batch processing Suns-VOC tool.

description: Many new module designs feature cut cells, especially now that cell and module manufacturers are introducing larger wafer formats (166mm, 182mm, and even 210mm in edge length). However, the cutting procedure introduces extra power losses. This recombination occurs when the cut edge is damaged by a high power laser or exposed to the air without passivation. In this paper, we employ high resolution photoluminescence to investigate the effect of edge recombination on interdigitated back contact solar cells. Edge recombination losses are compared by comparing various photoluminescence profiles obtained from the samples with different structures and cut techniques. First, we compare various laser cutting techniques at various locations. Two questions are addressed: where to cut the cells and how to cut them. Last, we compare the repassivation ability of the samples with different cutting techniques and structures. Repassivation can be used to mitigate edge cut losses with specific cutting techniques.

description: Diamond wire sawing is the wafering technique which recently replaced slurry-cut wafering, due to reduced kerf-loss, lower process expenditures and increased speed. While this technology is successfully used to wafer the ingots, it introduces a strong macroscopic saw damage on the surface of the wafers. These saw marks introduce artifacts in images recorded by multiple characterization methods which lead to poor quality inspection of silicon wafers and solar cells. Instead of a cost intensive update of the implemented measurement systems for the inspection of sawdamaged wafers, we propose a novel denoising technique of the images of diamond-cut wafers using generative adversarial networks.
High Temperature superconductivity in a hyperbolic geometry of complex matter from nanoscale to mesoscopic scale

description: While it was known that High Temperature Superconductivity appears in cuprates showing complex multiscale phase separation due to inhomogeneous charge density wave (CDW) order, the spatial distribution of CDW domains remained an open question for a long time, because of the lack of experimental probes able to visualize their spatial distribution at mesoscale, between atomic and macroscopic scale. Recently scanning micro X-ray Diffraction (SmXRD) revealed CDW crystalline electronic puddles with a complex fat-tailed spatial distribution of their size. In this work we have determined and mapped the anisotropy of the Charge Density Waves (CDW) puddles in HgBa2CuO4+y (Hg1201) single crystal. We discuss the emergence of high temperature superconductivity in the interstitial space with hyperbolic geometry, that opens a new paradigm for quantum coherence at high temperature where negative dielectric function and interference between different pathways can help to raise the critical temperature.

description: With the latest developments at photovoltaics such as increasing wafer size and domination of bifacial modules at the market, resistive losses due to increased current became more important. As a result, use of half-cut, triple-cut or shingle technologies are anticipated to be the industry standard in near future where the series resistance losses are reduced by decreasing the generated current and increasing the voltage. However, despite the increase in the module performance, some mechanical damage and electrical losses caused by the cutting process may also occur. Thus, the type of cutting method is important to minimize these drawbacks. In the scope of this study, the effect of laser cutting method on the performance of bifacial PERC cells were investigated.

description: New critical perspectives are required to investigate forms of creative and critical writing that produce ecological knowledge and representation, to identify stylistic and structural features that strengthen or undermine environmental communication, and to appreciate narrative modes that may inspire a change in cultural mindsets and behaviours. The relationships between modes of communication and intergenerational dynamics are essential to understanding the power of environmental news and stories. Fairy tales and fables, in which the joy of the happy ending still resonates with doubts and fears, and dystopian and apocalyptic stories, in which destruction can raise palingenetic hope, are essential to environmental communication. David Attenborough’s ecology documentaries form a new green genre that blends the fairy tale and apocalyptic dystopia and uses entertainment to produce public understanding of the ecological crisis. Who is the narrator and how is the narrative built and delivered to develop environmental advocacy? Can nature documentary TV series contribute to changing consumers’ habits? Is the role played by celebrity conservationists and conservationist celebrities essential to promoting a cultural shift? These are intriguing questions raised by ecological narratives.

Near-synonyms of Anglo-Saxon and Latinate Origin

Year: 2022

description: This article examines the semantic relations holding between pairs of Anglo-Saxon and Latinate near-synonyms in present-day English, such as speed/velocity, sweat/perspire, shy/timid and before/prior. Meaning variation between etymologically unrelated lexical items expressing equivalent concepts has primarily been explained in terms of pragmatic principles, although the differences between them also result from constraints imposed by their denotational semantics. The analysis proposed aims to identify the nature of their semantic proximity not so much by observing meaning construal in specific contexts or the degree of collocational variation, but rather through the observation of how similarity of concepts is conventionally encoded and externalized. This approach has made it possible to provide a preliminary mapping of the areas of overlap and contrast between semantically related items. Eight main scenarios emerge from the analysis of the data: the pairs of words examined are linked by a generic-specific (or specific-generic), literal-figurative (or figurative-literal) or cause-effect relation, but also differ in terms of focus, conventional implicatures or level of iconicity. Some possible lexicographic representations of these meaning relations have been proposed for English monolingual and learners’ dictionaries.

People-building Strategies in Trump’s and Biden’s Political Discourse

description: Social-identity creation is crucial for politicians to rhetorically build their political community, legitimise specific actions and mobilise supporters by appealing to specific values or discursive argumentations. Combining a critical discourse analysis perspective derived from van Dijk’s socio-cognitive approach with Conceptual Metaphor Theory, this paper investigates people-building discourse strategies in Donald J. Trump’s speech prior to the Capitol Hill riots and President Joseph R. Biden’s Inaugural Address. The research aims to compare strategies adopted in populist and anti-populist discourse. Results show that, while the distinction between populism and anti-populism is still underdeveloped, similar discourse strategies and metaphorical mappings chiefly revolving around the ideas of nation and democracy may be deployed with opposite ends. Furthermore, the study highlights how the populist/anti-populist frontier is not clear-cut and may shape different civic identities and ideals of democracy according to the ideology underpinning each politician’s discourse.

description: The main objective of this study is to identify determinants of deposit mobilization in commercial bank of Ethiopia. Accordingly, the researcher adopts quantitative research approach. The reason for using such method on this study is due to usage of secondary data for analyzing the determinants of bank deposit. In this study time series data covering 1998 and 2018 was analyzed. First, the time series data were assessed using descriptive statistics for the variables as well as the test for unit root test, heteroskedasticity, autocorrelation and normality testing to know if the assumptions of CLRM violated or not. Accordingly the result of Unit root test (i.e. the data is stationery at first level both ; Augmented Dickey fuller test and Phillips-Peron tests ), Model Stability test(i.e. the study model was stable) , Heterodosicity test (there is no heteroscedasticity problem ), Autocorrelation test(as long as explanatory variables, regardless of their true significance there is no evidence for the presence of autocorrelation on the study) and Normality test(i.e. the study data were consistent with a normal distribution). Estimation was done using Ordinary Least Squares technique by E-views9 statistical package. The results from economic analysis showed that deposit has a positive relationship with GDP, individual foreign remittance, deposit interest rate and number of branch opening and a negative relation with inflation. Among these variables, branch opening is an important strategy for deposit mobilization, it is highly significant than others. Individual foreign remittances is also significantly affects CBE's deposit next to branch opening. The data gathered from different organs were depicted in graph and it magnifies or clearly shows growth of each variables. Finally, the study ends with recommendations on determinants of deposit mobilization
The Discursive (De)Construction of Climate Change Advocacy

Publisher: name: Iperstoria

description: This paper studies the climate-related discourses of two (sets of) actors with a significant following on the two poles of the current US climate debate: the climate advocacy of one of the most vociferous US environmentalists in office, House Rep. Alexandria Ocasio-Cortez, and the delegitimizing climate counternarratives fashioned by mainstream conservative media outlet Fox News. Specifically, it centres on the processes that govern the argumentative framing of the 2019 policy proposal known as the (US) Green New Deal Resolution (GND) within Rep. Ocasio-Cortez’s tweets and news segments on the GND posted on the official Fox News YouTube site. Guided by the analytical framework delineated in Fairclough and Mădroane (2020), this paper seeks to lay bare the ways in which these two deliberating agents made selected premises salient and overriding, used linguistic devices to (re)define and (re)categorize phenomena, and had recourse to macro speech acts such as explanations and narratives to support their intended aims. In exposing the mechanisms that govern the framing of the critical issue of climate change and the debate of an environmental policy, it hopes to contribute to understanding how framing strategies are employed within policy debates that unfold in less formal contexts and to shed light on the communication of climate-related issues in ways that more effectively resonate with the public and counteract climate scepticism and denial.

“Visit our Ancient Factories and Book your Tour”

description: Enogastronomic tourism refers to clients’ specific enthusiasm for visiting the area in which a product is made so that they can taste and buy at the source. This form of tourism has indeed become highly popular in Italy too, developing in several branches of the agri-food sector. As a result, a considerable number of Italian wine, vinegar and/or cheese producers are offering their (prospective) foreign clients special tours aimed at tempting them into booking a stay, encouraging them to discover the picturesque natural locations and eventually to buy their top-quality products. With this purpose, the promotional discourse on Italian websites offering such tours must aim “to persuade, lure, woo and seduce” (Dann 1996, 2) visitors, convincing them to discover the Italian countryside and products. Since (re)presenting places and its people is not guided by a “value-free” (Pritchard and Morgan 2001, 177) perspective, but rather by the deliberate intention to promote such destinations, comprehending how discourse is moulded to influence readers’ perception of the local context would seem relevant. This paper aims at investigating the linguistic strategies used in the digital environment to promote enogastronomic tours across Italy by mainly considering how phraseology and units of meaning extend participation framework and open the way for new communicative contexts. Basing the investigation on both quantitative and qualitative methods, the English versions of a corpus of Italian wine, vinegar, beer, pasta, olive oil and cheese websites (around 100) will be taken into consideration in order to analyse how online narrative contributes to promoting this form of tourism as well as to understand how clients’ experience positively coexists with the promotion of local/regional products (Meluzzi and Balsamo 2021).

The Language Iceberg

description: One of the many important lessons imparted by corpus linguistics is that the information supplied in dictionaries and grammars represents no more than the tip of an iceberg. In lexicography, the object of description is fundamentally the lemma. When more specific details are not supplied, the assumption on the part of the average dictionary user is in all probability that the various forms of any given lemma show not only similar frequency and lexical environment but also similar meaning. It would appear that inflectional forms are under-represented in dictionaries. In the literature, very little attention has been devoted to inflectional forms, and in particular to their raw frequency. The frequency rates of the forms of a single lemma can not only differ markedly from each other but can also prove to be far higher or lower than the average for single inflectional forms, something which has important implications for language learners and which could therefore claim more emphasis in language-learning materials. The main focus of this paper will be on the frequency of inflectional verb forms as represented in dictionaries, including a final case study of the frequency of such forms within some idiomatic expressions. The question lying at the heart of this work is whether the raw frequency of inflectional forms should occupy a more important position in language-learning materials. However this may be, the counting of inflectional forms can reveal new and surprising insights into the vast and mostly untamed wilderness of language.

Assessment of strategic management practices: the case of private commercial banks in Ethiopia

description: The aim of this thesis is to assess the strategic management practices of private commercial banks in Ethiopia. This descriptive study adopting a quantitative research techniques answers two basic research questions, first the extent to which private commercial banks formulate, implement, evaluate and control its strategy. Second, the major challenges faced on the process. A systematic random sampling method was used to select four representative private commercial banks in Ethiopia from a list of sixteen based on their year of establishment. To further decide on the sample size from each selected Banks, a proportionate sampling method was applied. Finally, simple random sampling technique was used to identify the sampled respondents'. As data collection instrument, AMCES questionnaire was adopted after securing written approval and in consultation with the advisor. The reliability of the tool applied was tested and obtained a Cronbach alpha value of 0.833. The questionnaire was administered to 246 randomly selected employees, who have an involvement on the strategic management process. From the findings, it was learnt that the result obtained for strategy implementation and evaluation & control practice of private commercial banks was below the mean score. Therefore, the study concluded that private commercial banks focus more on the strategy formulation while giving less emphasis to strategy implementation, evaluation and control. The study finally recommended the need for the Banks to give due attention for strategic implementation in terms of human resource capability and Board support and on strategy evaluation and control with regard to performance measurement, communication and timely responsiveness to noted gaps.
Affection, Attraction and Aversion

description: The multi-faceted nature of the climate crisis in The Ice People (1998) by Maggie Gee is examined from an interdisciplinary perspective aimed at highlighting ways in which the joint effort of the humanities and the sciences can achieve effective environmental communication and audience engagement. An ecocritical reading of the novel incorporates the “Biophilia Hypothesis” (1993), a set of values through which Edward O. Wilson and Stephen Kellert have articulated genetic explanations to historical or emergent cultural patterns. Biophilic and biophobic values shed light on how humans affiliate to the other-than-human. Throughout the fictional apocalypse, biophobic values such as Aversion reveal the fracture between human beings and other species while Attraction, Affection, and other biophilic values are exploited for biophobic reasons. The values supporting our innate affiliation to nature can be identified, decoded, deconstructed, and consciously implemented to foster a novel cultural climate able to avert the climate apocalypse.

“You Think We Fixta Git up off Dis Block for Real?”

description: The process of othering of black people in the US can be traced back to the Atlantic Slave Trade, and the identity produced by such legacy is constantly haunted by a past—that of slavery and segregation—and by a present—that of systemic racism—that cage it in the slave ship, in the plantation, in the ghetto. Read in this light, Black condition is an ongoing process of mourning and awakening in which identity formation entails a peculiar form of agency, a “wake work”—in Christina Sharpe's words—capable of rupturing and subverting and, therefore, of imagining new ways to deal with the afterlife of slavery. My paper analyzes how the persistence of systemic antiblackness urges black people to engage the paradox of living within a transgenerational grief while rupturing it. To do so, I will examine the play Pass Over by Antoinette Nwandu, in its filmed version by Spike Lee (2018), which combines Beckettian and Biblical themes to depict Black condition as a combination of irreconcilable opposites and shows how, to borrow from the opening paragraph of Fred Moten’s In the Break, “the history of blackness is testament to the fact that objects can and do resist.” In the play, Moses and Kitch are stuck in a block of Chicago, determined to pass over and “rise up to their full potential,” like Jewish people in the Exodus. Despite their efforts, their dreams of the promised land collide with US reality and the objectified identity that has been forced on them.
