The choice of a particular PV-technology for “best performance” at a location is sometimes based solely on the label specification or single operating condition—and may not consider multiple parameters that affect different technologies with distinctly different impacts. In this paper, the choice of appropriate PV technologies for moderate-to-harsh soiling/climate conditions is evaluated based upon frequently opposing parameters of spectral effects (relating to solar resource, module spectral response, and soiling layer properties) and module temperature (linked to module construction and absorber bandgap). This paper builds on a linear model based upon soiling rates and the temperature coefficients of the module technologies. The model is validated with extensive experimental soiling data for crystalline Si and thin-film CdTe, with model discussions for CIGS and a-Si:H—covering the range of bandgaps from 1.1 eV through 1.7 eV for valid intercomparisons. The paper provides analytical and correlated experimental information to predict, compare, and identify the “best-of-class” performances for these module types under tropical climate-zone conditions.","PeriodicalId":6773,"journal":{"name":"2020 47th IEEE Photovoltaic Specialists Conference (PVSC)","volume":"13 1","pages":"2099-2103"},"PeriodicalIF":0.0,"publicationDate":"2020-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85013800","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 work, we investigate the role that the geometry and shape of the PV module can have on mitigating soiling losses from dust deposition and accumulation. We evaluate the soiling loss and specific yield of 6 different modules, one being a cylindrical module, under outdoor exposure for 12 months. The results show favorable soiling ratio for the cylindrical module throughout the year, which can reach up to three-fold reduction in soiling losses when compared to traditional modules in the study. The cylindrical module also shows stable soiling loss percentage which remains below 10% under all but severe dust events, where best-case soiling losses of above 20% were observed from the other modules under the same conditions. When left uncleaned, the cylindrical module has a higher specific yield than four of the five studied soiled modules, highlighting the potential benefits of utilizing the modules geometry for soiling loss mitigation, especially for deployment in environments where regular cleaning is not feasible.","PeriodicalId":6773,"journal":{"name":"2020 47th IEEE Photovoltaic Specialists Conference (PVSC)","volume":"1 1","pages":"0606-0610"},"PeriodicalIF":0.0,"publicationDate":"2020-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85614032","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}

RbF treatment with reduced CdS thickness shows an improvement in Voc and efficiency in this sample series, and also results in high FF and doping ~ 1016cm−3. Cells with reduced sodium show a decrease in Voc and infrared QE results suggest a higher optical minimum bandgap. Heat and light soaking experiments at 50, 65, and 75 °C, open and short-circuit junction bias under AM1.5G illumination suggest stabilization of CIGS solar cells with addition of Na and RbF. SCAPS-1D simulations suggest reduction in thermally ionized defect density in ordered vacancy compound (OVC) and changes in conduction band offset with RbF post-deposition treatment. Further, simulations show an increase in shallow acceptor and donor density after open-circuit and short-circuit AST respectively.

Local Al-BSF of a traditional PERC was replaced by p+ poly-Si/oxide passivated contact composed of ~15Å thick chemically grown tunnel oxide, capped with 120-250nm thick p+ poly-Si layer grown by LPCVD. Process optimization resulted in full-area un-metallized recombination current density (J0b, pass) of < 5fA/cm2 for planar surface, nearly independent of poly-Si thickness in this range. Metallized Jo showed an increase with decreased poly-Si thickness and was found to be 9.6 and 25fA/cm2 for 250nm and 120nm poly-Si respectively, with 4.6% direct metal-Si contact fraction, suitable for bifacial cells. A 21.4% baseline PERC cell with local BSF was fabricated and characterized to extract the rear side recombination current density (J0b,) of 65fA/cm2. Detailed analysis and device simulation showed that by replacing this LBSF with 250nm TOPCon developed in the study should produce a Voc enhancement of 9.2mV, consistent with the observed cell Voc increase of 10mV.","PeriodicalId":6773,"journal":{"name":"2020 47th IEEE Photovoltaic Specialists Conference (PVSC)","volume":"35 1","pages":"0821-0824"},"PeriodicalIF":0.0,"publicationDate":"2020-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76607586","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}

A major difference is that problems with the operation of photovoltaic systems are often treated confidentially and, unlike other industries, no general recalls are issued as they are common in automotive or telecommunication industry. This does, however, not mean that no issues exist. The PV industry is unfortunately still at a stage where quality assurance is often seen as an avoidable cost. There are three problems discussed which could have avoided problems (1) Equating IEC certification with quality control, (2) No relevant component tests, (3) Cost driven supply chain management. In here we present a generalized Quality Assurance (QA) scheme as a feasible approach for the PV industry and brought into context to more developed industries. Most examples will be for PV modules within this contribution but are not limited to those. However, the quality assurance must consider the final product, in the case this must always refer to the PV system at a particular location as a whole not just individual parts or design stages.","PeriodicalId":6773,"journal":{"name":"2020 47th IEEE Photovoltaic Specialists Conference (PVSC)","volume":"74 1","pages":"1675-1679"},"PeriodicalIF":0.0,"publicationDate":"2020-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85535098","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}
