The CIGS thin films were selenized in a closed-space graphite container. The result of selenization was characterized by Raman spectroscopy, EQE and the current-voltage-temperature measurement. After selenization at 350°C, the current-blocking behavior is inhibited and Voc increases from 310mV to 640mV. Until now, the efficiency near 9% can be obtained by an optimized selenization process.","PeriodicalId":6350,"journal":{"name":"2013 IEEE 39th Photovoltaic Specialists Conference (PVSC)","volume":"47 7 1","pages":"0362-0364"},"PeriodicalIF":0.0,"publicationDate":"2013-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76677209","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}

Natural grime accumulation is time-consuming and location-specific, and thus does not provide reproducible results across different geographic regions. Therefore, we have demonstrated a technique to apply artificial soiling with NIST-traceable components using an aerosol spray technique. This approach produces consistent soil coatings which were directly correlated to performance loss of multicrystalline Si cells in a laboratory setting. By tailoring the composition of the test blend, termed `standard grime', the loss due to soiling can be effectively predicted over a range of mass loadings and soil types.","PeriodicalId":6350,"journal":{"name":"2013 IEEE 39th Photovoltaic Specialists Conference (PVSC)","volume":"547 1","pages":"1542-1545"},"PeriodicalIF":0.0,"publicationDate":"2013-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77072313","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}

One of the solutions offered in the literature to overcome this limitation is to design the system for higher PV and/or battery voltage levels. However, increment in the PV/battery voltage level makes design and installation issues of the system more involved in order to satisfy concerns pertaining to the safety of the personnel and equipment. In order to address the aforementioned limitations of the existing standalone PV systems, a topology involving a novel boost inverter which does not require the increment in the voltage levels of PV array and/or battery is proposed in this paper. Detailed analytical studies of the system are carried out.

Designers and operators of utility-scale solar power plants are increasingly seeking methods to quantify soiling-related losses, in order to improve performance modeling and verification or to optimize washing schedules. Recently, soiling measurement equipment has been introduced based on the measurement of two co-planar PV modules, one of which is regularly cleaned, and the other of which naturally accumulates environmental contaminants. These measurements are used to determine a soiling ratio (SR), which may be applied as a derate factor in analysis of the PV system performance. In this work, we examine the difference between a soiling ratio metric calculated from measured temperature-corrected short-circuit current values (SRIsc), which represents the fraction of irradiance reaching the soiled modules, versus a soiling ratio calculated from measured temperature-corrected PV module maximum power values (SRPmax), which represents the fraction of power produced by the soiled modules compared to clean modules. We examine both techniques for CdTe and c-Si module technologies. This study is motivated by the fact that variations in module efficiency versus irradiance, as well as any non-uniformity of soiling, may introduce differences between the power losses estimated from short-circuit current values versus actual soiling-induced power losses. For CdTe, the SRIsc method is found to be a good proxy for the SRPmax method for nonuniform soiling levels up to 11%.","PeriodicalId":6350,"journal":{"name":"2013 IEEE 39th Photovoltaic Specialists Conference (PVSC)","volume":"37 1","pages":"3004-3009"},"PeriodicalIF":0.0,"publicationDate":"2013-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82086099","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}
