BWRs extracted from the solar panel image and a surrogate checker pattern are correlated with the PV cell soiling loss measured via short circuit current method. A linear correlation was found between the BWR and the soiling loss of the PV reference cell. In addition, the surface dust loading estimated from the BWR agreed well with the PV reference cell’s soiling loss and dust potency information. However, it was found that BWR extracted from the lab PV cell is subject to over exposure and uncertainty, which calls for using field-size PV panel or the checkered board pattern as a surrogate. The results further demonstrated the utility of image-based soiling quantification and its feasibility for use in the field.","PeriodicalId":6788,"journal":{"name":"2021 IEEE 48th Photovoltaic Specialists Conference (PVSC)","volume":"42 1","pages":"2264-2269"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79222758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with current-voltage (I-V) sweeps available to determine the solar cell parameters, much information is lost if only four standard values (Voc, Isc, Vmpp, Impp) are used for further analysis. In this paper we present extended solar cell parameters which allow a compact and standardized description of a complete I-V characteristic. Furthermore, the extended solar cell parameters are readily combined with the IEC60891 norm to obtain a temperature and irradiation dependent I-V model. We demonstrate that using this model also more subtle changes in the shape of the I-V characteristics can be effectively monitored.","PeriodicalId":6788,"journal":{"name":"2021 IEEE 48th Photovoltaic Specialists Conference (PVSC)","volume":"9 1","pages":"1560-1564"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83477938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efforts have succeeded in making materials and devices which pass standard silicon durability tests, but accurate prediction of lifetime using accelerated degradation tests requires deep understanding of degradation mechanisms. We track the kinetics of the perovskite to non-perovskite phase transition which is found in many of these materials using a prototypical cesium lead halide compounds. Further exploration of this phase transition should lead to better predictions of material and device stability.","PeriodicalId":6788,"journal":{"name":"2021 IEEE 48th Photovoltaic Specialists Conference (PVSC)","volume":"1 1","pages":"0226-0228"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83518200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, as new concept for bifacial technology in urban environment needs, we have proposed automated sun trackable and shape transformable 2-D tessellated bifacial module at the sun position that can be applied to at any curved surface, and change their shapes according to AOI to receive more solar energy and maximize power output without external helps. With this introduced self-shape-transformable 2-D tessellated bifacial module with intervals and reflector, 47% enhanced power output obtained compared to flat module.

Around 12.6% efficiency has been reported for CZTSSe based solar cell in the literature. Surface recombination at the back contact of the solar cell has been considered to be an important limiting factor for the constrained values of efficiency. One of the possible ways to overcome this limitation is to introduce a back surface layer (BSF) in the cell. We in this paper report our results and analyze the same for possible adoption of the BSF layer of tungsten diselenide (WSe2) material in a CZTSSe based solar cell. The results show significant enhancement in open-circuit voltage (VOC), short-circuit current density (JSC) and fill factor (FF) due to introduction of BSF which increases its power conversion efficiency (PCE) from 12.57% to 17.20%. All the simulations in this research work are performed using SCAPS-1D simulator. Present research work may be an important step toward suggesting CZTSSe based solar cell structures with higher values of efficiency than currently being reported in the literature.","PeriodicalId":6788,"journal":{"name":"2021 IEEE 48th Photovoltaic Specialists Conference (PVSC)","volume":"41 1","pages":"2020-2022"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82673452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By analysing current collection across the device heterointerfaces, we investigated the effect of (i) perovskite thickness on the short-circuit current density (Jsc) of the tandem device and (ii) temperature on devices performance. We deployed an advanced opto-electrical modelling framework based on optical sub-models from GenPro4 and on self-consistent fundamental semiconductor equations implemented in TCAD Sentaurus . Using these simulations of perovskite/c-Si tandem solar cells, an in-depth analysis of the physics of current contribution of supporting layers has been carried out. Solving numerically the fundamental equations of semiconductors, we theoretically show for the first time that electron-hole pairs photo-generated in the TRJ can be collected, effectively boosting Jsc values well beyond (photocurrent density) Jph levels. In addition, a temperature-based study of these perovskite/c-Si tandem solar cells has been performed to evaluate the temperature coefficient which is useful for their energy yield simulations.","PeriodicalId":6788,"journal":{"name":"2021 IEEE 48th Photovoltaic Specialists Conference (PVSC)","volume":"36 1","pages":"0303-0305"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88794618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
