Year: 2019

description: In the current competitive business atmosphere, industry is facing plenty of challenges notably obtaining the proper employees and retaining them. This research study has been conducted on companies in Hawassa Industrial Park to highlight importance of the non-financial rewards in terms of their effectiveness as well as efficiency. The purpose of this study was to seek out the effects of varied non-financial reward practice on employees' retention. The assorted independent dimension includes Recognition, Training, Work Life Balance and Physical Work Environment. Both primary and secondary data source were used, primary data were collected form 315 respondents through questionnaires selected using stratified random sampling. A Descriptive and explanatory research design has been applied in this study. Questionnaire contents were adopted from past research and Paul E. Spector employee recognition program handbook. The adopted questionnaires were measured on a five point likert scale used to collect data from respondents; spss version 20 software has been used to analyze the data for descriptive and inferential statistics. The result of the study shows that among the non- financial reward practice training and physical work environment have a positive and significant effect on employee retention. Furthermore the variables employed in the model explain 60% of the variation in employee retention also the beta coefficient in the multiple regression analysis shows that non-financial reward studied had a positive influence in bringing a variation in employee retention. The result from the descriptive analysis revealed that the respondents low agreement on the non-financial reward practice studied, this implies that the practice of these rewards of companies in the park were inadequate to retain their employees. The study suggest that companies should have to give mush emphasize on non-financial reward practice to retain their employee. This research will be supportive and fruitful for HR managers in industrial sector by coming up with a good compensation package to retain their competent employees.

description: In this work, we demonstrate a novel semi-transparent solar cell based on ultrathin hydrogenated amorphous Si/Ge multiple quantum wells (MQW). This concept allows extra degree of freedom for both optical design and bandgap engineering compared to single QW structures. Mainly, the multiplication of the QWs number in a periodic configuration, taking advantage of effective synergy between electronic and photonic confinements, leads to an improvement of photocurrent, while preserving high voltage and fill factor and ensuring significant transparency. The MQW new concept yields a boost in power conversion efficiency up to 3.4% and a considerable average visible transmission of about 33%. The achieved performance points out the promising potential of the proposed semitransparent ultrathin QW solar cell for glass façades and solar windows applications.

description: Fast-and-slow models of decision-making are commonly invoked to explain economic behaviour. However, past research has focused on human cooperation and generosity and thus largely overlooked situations where there are sharp conflicts between efficiency and equality, or between efficiency and more intuitive moral values (repugnance). Here, we contribute to fill this gap in the literature. We conducted a preregistered experiment (n = 1500 recruited from Prolific) to assess the effects of fast, intuitive decisions, under time pressure versus slow, deliberate decisions, under time delay, on (i) people's distributional preferences and (ii) their attitudes toward repugnant transactions. The results show increased preference for equality and decreased preference for efficiency under time pressure, but no effects on moral repugnance. Exploratory analyses revealed that most of the observed treatment effects in our data were accounted for by women. Our results provide some support for theories that associate controlled cognition with concern for efficiency, and intuitive, emotional responses with inequality aversion.

description: Silver (Ag) pastes are widely used in the global market for most solar cell architectures. In particular, lead (Pb) is no longer wanted in productions for environmental reasons. In this work, a model for the contact formation between Pb-free, tellurium (Te) oxide containing screen-printable Ag pastes and silicon is presented. It is shown that Te plays a key role in this model. Te is not only an important part in etching the surface passivation layers with TeO2 dissolving the dielectric layer, but also for a formation of the contacts with Te forming a compound consisting of Ag2Te. Using EDX mapping, precise contact regions can be examined and interpreted for contact formation. The used paste is a novel developed commercial paste which is on a par with other pastes used in industry concerning the resulting contact properties. This is also demonstrated in this work by the very low contact resistances of less than 1 mΩcm2 over a wide range of fire peak temperatures. It is additionally shown that good resistances can be achieved on both nand p-doped regions.

description: Within this work, we discuss the evaluation of innovative glass-based stencils starting with in-depth computational fluid dynamics (CFD) simulation of different channel geometries using COMSOL Multiphysics©. Based on these simulations, a special hour-glass shaped channel geometry has been identified which theoretically enabled the direct printing of contacts with a triangular cross-section using stencil printing. With the expertise of the involved partners LPKF Laser & Electronics AG and Christian Koenen GmbH, several sets of LIDE-structured glass foil stencils have been fabricated and tested on a semi-automatic screen printer at Fraunhofer ISE. Within these tests, the prediction of stencil-printed triangular contacts could be impressively verified on Cz-Si PERC solar cells. Due to the optimal reflection properties of such a contact shape, this could enable effectively “transparent contacts” in the future and thus represents a long-lasting dream of all solar cell metallizing specialists. Furthermore, glass foil nozzle plates were manufactured for the parallel dispensing technique by LPKF Laser & Electronics AG to demonstrate the proof of concept for an alternative, cost-effective material including production costs for nozzle plates compared to the standard material. LIDE-structured glass foils showed promising results in the multi-nozzle dispensing process to be used in the future within further optimization in the manufacturing process.

description: We study objective Bayesian inference for linear regression models with residual errors distributed according to the class of two-piece scale mixtures of normal distributions. These models allow for capturing departures from the usual assumption of normality of the errors in terms of heavy tails, asymmetry, and certain types of heteroscedasticity. We propose a general noninformative, scale-invariant, prior structure and provide sufficient conditions for the propriety of the posterior distribution of the model parameters, which cover cases when the response variables are censored. These results allow us to apply the proposed models in the context of survival analysis. This paper represents an extension to the Bayesian framework of the models proposed in Rubio and Hong (2015). We present a simulation study that shows good frequentist properties of the posterior credible intervals as well as point estimators associated to the proposed priors. We illustrate the performance of these models with real data in the context of survival analysis of cancer patients.

description: Increasing the sheet resistance of the phosphorus-doped PERC solar cell is a way to improve the solar cell efficiency. In current work, trials for increasing the sheet resistance for PERC solar cell from 140-150 Ω/ to 180-185 Ω/ by varying the POCl3 flow and the pre-deposition & drive-in temperatures have been carried out. By stopping the POCl3 flow during heat-up between pre-deposition and drive-in step, the sheet resistance increased to 230 Ω/ with a higher standard deviation. By increasing the pre-deposition and drive-in temperature by 5°C, the Isc and Voc improved while the average FF decreased due to higher zone-wise sheet resistance variation. Altering the recipe with no POCl3 flow during heat-up from pre-deposition to drive-in phase and decreasing the POCl3 flow in the pre-deposition step provided a better way to increase the emitter sheet resistance. Reduction of POCl3 flow during the pre-deposition phase, enabled to obtain average sheet resistance values in the range of 170 Ω/ to 185 Ω/. A sheet resistance value of 175 Ω/ led to a gain of 0.05% absolute compared to the baseline production recipe. Better finetuning of zone-wise sheet resistance can lead to increased gain in the Voc and Isc without adversely affecting the FF.

description: In this work we report on the development of an industrially relevant in-situ doped sputtering process for depositing 100-150 nm thick aSi(n) layers to passivate the rear contact of TOPCon solar cells. All relevant properties of the poly-Si layers have been optimized using symmetrical lifetime samples. The sputtered aSi(n) layers do not show blistering effects and can be doped with Phosphorus concentrations larger than 1E21 at/cm³ which has been evaluated via calibrated SIMS measurements. ECV measurements of optimized layers after a high temperature anneal at 850-980 °C for 10-30 min confirm the necessary electrically active concentration cP ~ 1-3E20 at/cm³. After tuning the interfacial oxide layer and optimizing the PVD process parameters as well as the annealing process implied open circuit voltages iVoc > 735 mV could be measured on symmetrical lifetime structures at one sun injection density on 1-3 Ωcm n-type Cz-wafers. Corresponding sheet resistances of the 140 nm thick poly-Si layers range from 60-320 Ω/sq and sufficiently low specific contact resistivities below 10 mΩcm² for screen-printed contacts have been determined accompanied by low recombination of J0,met < 65 fA/cm². The best TOPCon solar cell with sputtered poly-Si layers has an efficiency of 23.4 % measured by ISE CalLab PV Cells.

description: A recursive approach to determine the Hilbert-Schmidt measure of pairwise quantum discord in a special class of symmetric states of $k$ qubits is presented. We especially focus on the reduced states of $k$ qubits obtained from a balanced superposition of symmetric $n$-qubit states (multiqubit Schrödinger cat states) by tracing out $n-k$ particles $(k=2,3, \cdots ,n-1)$. Two pairing schemes are considered. In the first one, the geometric discord measuring the correlation between one qubit and the party grouping $(k-1)$ qubits is explicitly derived. This uses recursive relations between the Fano-Bloch correlation matrices associated with subsystems comprising $k$, $k-1$, $\cdots$ and $2$ particles. A detailed analysis is given for two, three and four qubit systems. In the second scheme, the subsystem comprising the $(k-1)$ qubits is mapped into a system of two logical qubits. We show that these two bipartition schemes are equivalents in evaluating the pairwise correlation in multi-qubits systems. The explicit expressions of classical states presenting zero discord are derived.

description: Mitigating LID for PERC solar cells has been extensively researched and severe degradation after field-level exposure has been minimized due to regeneration processes integrated in the solar cell production lines. It is observed that without the LID regeneration process, the relative degradation in PERC cell efficiency is more than 5.0%. With the production electrical injection based LID regeneration recipe, the relative efficiency improvement is more than 1.0%, whereas the trial recipes had a relative gain of 0.3%-0.9%. LID light-soaking show that the baseline production recipe also has a degradation of less than 0.5% compared to the trial recipes. The new trial recipes demonstrate lower degradation compared to baseline production regeneration recipe under LeTID light soaking. Module level light-soaking results show a degradation of 1.4% for trial recipes compared to the baseline regeneration recipe which had a degradation of 1.8%. The results indicate that for electrical injection based LID regeneration, a constant temperature of 160-180°C and constant current of 10 A is more suitable than the current production recipe.

description: Holding optimum inventory and satisfying customers demand with sufficient service level is a challenging task. To keep a good balance between inventory level and sufficient service level implementing appropriate demand forecasting model plays important role in inventory management system of spare parts. The purpose of this thesis study is to recommend a better demand forecasting approach for spare parts inventory management of MOENCO from models suggested in literatures that provides a better solution in keeping a good balance between stock holding amount and service level. Companies who implement appropriate demand forecasting model will have less tied up capital, reduce operational & overhead costs, and lower wastage of wealth due to obsolescence & scraping while satisfying customers demand with sufficient service level that helps to sustain in business with good profit. A model suggested in literatures called approximation demand forecasting model selected to simulate sample spare parts data obtained from MOENCO database. With 2 weeks aggregated demand, and 4 months lead time period optimum values of smoothing constant of demand size (αz), smoothing constant transaction interval (αi), and forecasted demand identified by simulation with Microsoft Excel, that provide the least average MAPE. Then, the stock amount and service level calculated, and compared with the existing inventory model to prove its effectiveness. It is observed that approximation model can be considered as a good managerial tool for automotive parts inventory management system of MOENCO to have optimum stock holding position with sufficient service level so that, it reduces capital tied up, enhances efficient cost management, and efficient utilization of forex with acceptable service level, and hence maximizes the profitability of the business. This thesis work can be more enhanced by testing spare parts inventory data of other similar companies using approximation method that include different demand patterns.

description: In this work, we demonstrated that the p-type PERC solar cells can also be improved front side performance based on front side SiN/SiON anti-reflection coating (ARC) layer structure. Improved ARC layer was obtained by depositing the SiON layer after the SiN layer. By changing the n value of SiON layer through the process parameters, it can be found that the short wavelength can be improved, and the photocurrent can also be increased by about 56mA. About 0.1% gain in conversion efficiency was obtained compared to the result of reference solar cell. Finally, the potential induced degradation (PID) test of SiON PERC solar cell is also in compliance with IEC TS 62804- 1 specifications.

description: Screen-printing technology has already become the dominant metallization technique for silicon solar cells in the PV industry. Despite significant progress and improvements in the performance of screen-printed contacts during the past decades, one remaining challenge for screen-printed solar cells is the formation of highly recombination-active metal/Si interfaces, which can result in substantial carrier recombination losses in screenprinted PERC solar cells and the emerging high-efficiency TOPCon solar cell technology. With the bulk and surface passivation quality continuously improving in industrial silicon solar cells, the impact of such contact recombination losses will become more and more detrimental and eventually become the limiting factor to the efficiency of screenprinted solar cells. To minimize such losses, the metal/Si interface area needs to be greatly reduced for screen-printed contacts. In this work, preliminary results on the development of two novel metallization designs are presented. Both approaches aim to significantly reduce contact recombination of screen-printed contacts via reducing the metal/Si interface areas while maintaining compatibility with current screen-printing capabilities. The fabrication of proof-ofconcept PERC solar cells with the proposed contact structures demonstrated a promising VOC gain of up to 8 mV by reducing the metal/Si interface area from ~3.1% with industrial standard H-pattern grids to 0.5% with the dash metallization design. The key challenges encountered throughout the development are identified, and potential methods to overcome these challenges and achieve higher efficiencies in future work are also discussed.

description: The spontaneous localization mechanism of collapse models induces a Brownian motion in all physical systems. This effect is very weak, but experimental progress in creating ultracold atomic systems can be used to detect it. In this paper, we considered a recent experiment [1], where an atomic ensemble was cooled down to picokelvins. Any Brownian motion induces an extra increase of the position variance of the gas. We study this effect by solving the dynamical equations for the Continuous Spontaneous Localizations (CSL) model, as well as for its non-Markovian and dissipative extensions. The resulting bounds, with a 95% of confidence level, are beaten only by measurements of spontaneous X-ray emission and by experiments with cantilever (in the latter case, only for rC > 10^(-7) m, where rC is one of the two collapse parameters of the CSL model). We show that, contrary to the bounds given by X-ray measurements, non-Markovian effects do not change the bounds, for any reasonable choice of a frequency cutoff in the spectrum of the collapse noise. Therefore the bounds here considered are more robust. We also show that dissipative effects are unimportant for a large spectrum of temperatures of the noise, while for low temperatures the excluded region in the parameter space is the more reduced, the lower the temperature.

description: There have been many purported translations/decipherments of the ring found at Ezerovo in 1912, which is generally thought to contain one of the longest Thracian language inscriptions known, though its only a short inscription. In this essay, the author offers what he believes is the best of any translation/decipherment made so far, and one which has a high likelihood of being correct. The first version of this translation was completed early in October or late in September of 2020. In 2022 I decided that "tiltean" more likely meant "buried" rather than "fallen". In early February 2023, I decided that Tilezupta more likely meant "Bearing the Bow (the bow used for arrows)".
description: In this new 2023 version, I decide that Tilezupta more likely meant "Bearing the Bow", the bow being the bow used to shoot arrows. Zupta="bow", from "to curve, bend, arch", Tile="to bear". So check the Tilezupta section, which I have re-written. I realized some months ago that, though I'm most likely right about the meaning of Roli-, it does not derive from PIE *sreu-, and I show why in this version. I also fixed up and added to the "Tiltean" section". A few other fixes and additions, but no need to re-read the entire paper. I plan a further refinement soon, in a month or so.

description: Current motion and process sequences already lead to breakage in cell and module manufacturing under industry standard wafer cycle times. Increasing wafer throughput can lead to extreme handling challenges if the wafer needs to survive cell production undamaged. This investigation shows a method to analyze cell manufacturing processes regarding wafer damaging. A prototype handling process was developed, and damage was measured indirectly by the wafer strength. The statistical strength distributions of wafers are compared. The introduced procedure for wafer strength analysis was applied for the first time to evaluate high throughput manufacturing processes. Two handling operations modes, that means printing processes are compared to each other regarding the fracture stress distribution. The results show a decrease of wafer strength after handling by novel printing technologies. The rotary printing process and screen-printing was performed. Strength reduction was observed.

We identified a symmetry breaking structural transition at around $T_s = 150$ K, which matches a large bump in the electrical resistivity. Several new peaks are detected below that transition. Combined with first-principles calculations, our polarization-dependent measurements suggest a charge instability driven lattice distortion along one of the Ti-O bonds that breaks the 4-fold symmetry and more than doubles the unit cell.

description: Gated solar cell architectures promise to recover the efficiency loss due to interface degradation. Here, we address the impact of the material quality of the absorber layer and the efficiency recovery window of such gated solar cells. For a poorly passivated interface, the performance is limited by the interface recombination. With additional control gate architecture, the interface recombination at the rear interface can be reduced leading to the dependence of performance on the bulk lifetime of the solar cell. For surface recombination velocity (Sb) of 1000 cm/s, in comparison to the reference solar cell, the efficiency of the cell is improved by 1.28 % and 1.81 % for bulk lifetimes of 0.1 and 10 ms, respectively. Thickness-dependent gated solar cell results show that thicker cells require a higher bulk lifetime to achieve high efficiency, while thinner cells are rather independent of the bulk lifetime. Our results indicate that gated solar cells could be of interest to achieving high-efficiency solar cells with heterogeneous materials with low-cost fabrication.

description: The main objective of the study was to explore students reading attitude, reading instruction and reading performances. A descriptive research design which consisted of first collecting quantitative data and then collecting qualitative was used to investigate the attitude of learners towards reading skills. That is, both quantitative and qualitative data analysis techniques were employed to analyze the data collected. There were four main measurement tools employed in this study: 1) a questionnaire, 2) an interview, 3) a class room observation and 4) a reading test. These tools were used to measure the attitudes of the students towards reading skills. The subjects of the study were selected from Entoto Amba secondary school that is in grade 10. Ninety one students who were selected using stratified sampling technique filled in the questionnaire and took the reading test. Six students were randomly selected from the group for interview. Three teachers were chosen by using purposive sampling technique and they were observed. After the administration of the data gathering tools, the data were collected and analyzed. The quantitative data was analyzed using frequency count and percentage. The qualitative data was thematically analyzed. Attempts were made to triangulate the qualitative and quantitative data. Thus, the results of the questionnaire, individual interviews, class room observation and the reading test showed that most students held positive attitudes towards reading skills in most aspects even if they were not committed to do reading tasks. The results of the interview and the class room observation revealed that reading was not taught effectively. Students did not get adequate reading practices. In addition to this, the results of the interview revealed that majority of the students agreed that the class room teacher was better in teaching reading skills than the plasma teacher. The performance of the students in the reading test was also found to be average. Finally, the results of the study also revealed that the reading instruction and the students' reading performance were significantly interconnected. The study concluded that the weaknesses that the students show in reading in English are mainly rooted in the method of teaching reading. It is, thus, suggested that the teaching of reading in Entoto Amba secondary school needs a thorough revision in terms of the methodology used in the teaching of reading. Teachers also use the process and communicative approaches of teaching reading
title: Analysing stewardship in community forestry in the context of REDD+ implementation a case study from Nepal
Creators: name: Pandey, Raj Kumar
Publisher: name: University of Reading
Year: 2022

description: The main aim of this study is to understand stewardship in Nepal’s community forestry in the context of 
REDD+ (Reducing Emissions from Deforestation and Forest Degradation and the role of conservation, 
sustainable management of forests and enhancement of forest carbon stocks in developing countries) 
implementation. Stewardship is about fostering harmonised interactions and relationships between people 
and nature whereas REDD+ is a UN climate change initiative. This study analyses how REDD+ affects 
the three aspects of stewardship for Nepal’s community forestry namely forest management, livelihoods 
and equity, and governance at the community forest user group (CFUG) level.
Despite the fact that community forestry in Nepal has improved local forest stewardship to some extent, 
there are still stewardship issues, for example, passive forest management, inequity in benefit sharing, 
failure to maximise livelihood opportunities and insufficiency in decentralisation process. This study 
looks at how, to what extent and whether REDD+ can address the stewardship issues. It uses case study 
as a research method. The study takes place in five CFUGs participating in a REDD+ pilot project in 
Gorkha and Chitwan districts. Data for the study are collected from in-depth interviews, group 
discussions, field observations, CFUG minutes and other secondary sources. 
It is found from the study that REDD+ adopts conservation-oriented forest management rather than 
sustainable forest management, limits access to forests and practises restrictive harvesting from which the 
livelihood of forest poor is adversely affected. Furthermore, REDD+ tends to reinforce pre-existing 
inequity. It likely shifts community forestry towards a less participatory and more centralised forest 
governance. Findings from many other studies in the same project area and REDD+ cases from other 
countries are similar to the findings of this study. This study concludes that REDD+ less likely improves
stewardship in community forestry. In addition to this, the study offers invaluable insights to researchers, 
policy makers and other relevant stakeholders to better understand the impacts of REDD+ in community-based forestry.

description: This research was conducted in an attempt to investigate the status of sourcing practice(measured in terms of four dimensions, namely strategic purchasing, long-term orientation, communication and limited number of suppliers) and its relationship with operational performance in the MSF Ethiopia. Owning to the small number of the total population, the study had employed census survey to quantitatively assess the supposed relationship between the dependent and independent variables. Questionnaire was used as the formal instrument of data collection. A total of 60 questionnaires were distributed and 57 of them were filled and returned which made the response rate about 95% and of which 54 of them were found complete and hence qualified for being processed. The study findings have suggested that the levels of sourcing practices and operational performance are moderate in the case of MSF Ethiopia as the perceived evaluation of the respondents reply. It has also revealed that, though all of the dimensions of sourcing practices have statistically significant positive relationship with operational performance communication was found to have no statistically significant predictive power on operational performance of MSF, while the remaining three dimensions have found to have a statistically significant predictive power on operational performance of MSF. It is recommended that MSF is required to review its existing sourcing practices and make the necessary modifications in order to benefit from the performance improvements in terms of improved quality, swift delivery time, reduced cost of goods, and volume & mix flexibility of goods and satisfaction of internal customers

description: Tunnel Oxide Passivated Contact structure on p-type Si with rear full area hole selective passivating contact and n+ emitter (p-TOPCon) would be ideal successor for PERC. In this work, Sentaurus TCAD based simulation study is performed to investigate advantages of p-TOPCon over PERC with respect to surface passivation. Front and rear surface passivation effects are examined by considering surface recombination velocities (Srear and Sfront) at non-metallized Si surfaces. p-TOPCon and PERC outperform Al-BSF for identical cell parameters. p-TOPCon performance is less sensitive to Srear than PERC. Voc (efficiency) of p-TOPCon decreases for an order of magnitude higher Srear compared to PERC. Voc (efficiency) trends are identical for p-TOPCon and PERC with Sfront variation. There is a scope for performance improvement with enhanced front surface passivation. Conclusively, p-TOPCon performs better than PERC for identical bulk lifetime and front and rear passivation conditions.

description: A $r$-parameter ${u}_{\{κ_1, κ_2, \cdots, κ_r\}}(2)$ algebra is introduced. Finite unitary representations are investigated. This polynomial algebra reduces via a contraction procedure to the generalized Weyl-Heisenberg algebra ${\cal A}_{\{κ_1, κ_2, \cdots, κ_r\}}$ (M. Daoud and M. Kibler, J. Phys. A: Math. Theor. {\bf 45} (2012) 244036). A pair of nonlinear (quadratic) bosons of type ${\cal A}_κ\equiv {\cal A}_{\{κ_1=κ, κ_2=0, \cdots, κ_r=0\}}$ are used to construct, à la Schwinger, a one parameter family of (cubic) $u_κ(2)$ algebra. The corresponding Hilbert space is constructed. The analytical Bargmann representation is also presented.

description: Iron contamination in crystalline silicon can be quantified with high sensitivity thanks to its peculiarity to switch between interstitial and dopant-paired form, each exhibiting specific recombination activity. Typically, this is done by an iso-injective comparison of effective excess carrier lifetimes with iron either being interstitial or paired form. Within this contribution it is shown by means of PC1D simulations that the procedure works for solar cells as well, exploiting that effective lifetimes can be calculated from Voc data. Furthermore, it is shown that even a comparison of Voc’s taken at a constant intensity, meaning differing injection, already allows for a good estimation of iron contamination. Using multiple intensities allows an even better quantification.

Linear A, Knossos, Knosos, Mycenae

description: This one is one of my best: a lot of new connections/etymologies, and many etymologies from before revised and reimagined and made accurate. For example: the Kinna/Tianga/Tenga/Tunga in Kinnabaris/Tengabaris/Tiangabaris most likely meant "stone". Explaining why Spartacus/Sparadakus/Sparadokos didn't meant "Spear+famous" (as posited decades ago) but instead "strong, firm", and -akus, -akos is a suffix. Dzomb/Zomb (the European bison) most likely meant "strong, firm, powerful", and I detail why. My theory Knossos/Knosos='fortress", and that “Kn” in IE meant “firm, stiff, erect, pointed, sharp”. My etymology of Cattus (Cat), and much more.
description: One important typo: I meant to type "the application of Medokos/Metokos to a mountain range largely rules OUT the theory that "dokos/tokos"="famous". Doesn't completely rule that out, but I explain why, especially with the other factors, that statement is very likely accurate: it's largely ruled out.

description: This paper investigates the possibility of using low-cost consumer flatbed scanners for optical inspection of solar cell precursors. Two types of scanners, with contact image sensor (CIS) and charge coupled device (CCD) technologies, are used and compared for monitoring the texturing quality between and across multi-crystalline and mono-crystalline silicon wafers. The performance of the low-cost scanner in monitoring wafer reflectance is evaluated by comparing the outputs with the results from a high-end industry scanning spectrophotometer LOANA. The study shows good qualitative agreement and statistical correlation of multi-crystalline silicon wafer images measured with a low-cost flatbed scanner and the LOANA.
title: The extension problem for fractional Sobolev spaces with a partial vanishing trace condition
Creators: name: Bechtel, Sebastian
Publisher: name: Springer International Publishing
Year: 2024

description: We construct whole-space extensions of functions in a fractional Sobolev space of order s ∈ (0, 1) and integrability p ∈ (0,∞) on an open set 0 which vanish in a suitable sense on a portion D of the boundary ∂O of 0. The set 0 is supposed to satisfy the so-called interior thickness condition in ∂O\D, which is much weaker than the global interior thickness condition. The proof works by means of a reduction to the case D = ∅ using a geometric construction.

description: Solar cell (SC) heterostructures based on PEDOT:PSS/Si heterojunction with a flat and quasigrating type microrelief interface and two types of PEDOT:PSS films – pure and chemically doped have been fabricated and studied. It is shown that an increase in the SC efficiency occurs both due to texturing of the Si interface (increase in absorbed light due to decrease in optical losses), and improvement of electrical parameters of the polymer layer due to chemical doping (with DMSO) and post-fabrication treatment (washout of the PSS group). The maximum efficiency (4.82%) was obtained for SC heterostructures with a quasigrating Si interface and modified PEDOT film, which is 2-6 times higher than that for the similar structure and for structure with a flat interface.
