Here, we studied the structure and phase composition of sputter-deposited ACIGS thin films using X-ray diffraction (XRD), glancing incidence XRD (GIXRD) analyzed by Rietveld refinement, and Raman spectroscopy. Samples were deposited on stainless steel substrates with different back electrode selenization and absorber growth temperatures. XRD analysis showed that Ag-alloying of CIGS films led to splitting of the (220)/(204) and (312)/(116) peaks while they overlapped in a CIGS sample. Raman spectroscopy indicated formation of an ordered defect phase (ODC) for Ag-alloyed samples. The average A1/ODC peak area ratio was similar for the different growth temperatures but increased with reduced back electrode selenization. The sample with no K incorporation shows the highest A1/ODC area. Comparing the A1 Raman mode of the chalcopyrite phase at the surface and back-side of the absorber layer indicates that the higher absorber growth temperature lowered the Ga/III variation at the surface and the back of the film.","PeriodicalId":6558,"journal":{"name":"2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC)","volume":"15 1","pages":"0852-0855"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90952193","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}

This paper presents the sputtered NiO$_{mathbf {x}}$ to be a potential candidate as hole-selective layer for c-Si solar cell contacts. NiO$_{mathbf {x}}$ has a very small valence band offset (VBO $) ( sim 0.1$ eV) and a large conduction band offset (CBO) with Si $( sim 2$ eV), which makes it a promising candidate for hole-selective interlayer materials to reduce the contact recombination. In this paper, the effect of annealing condition on the NiO$_{mathbf {x}}$/Si interface quality is first evaluated by Hall resistivity measurement. Also, the transport of both majority and minority carriers due to NiO$_{mathbf {x}}$/Si band alignment is investigated by transmission line measurement. Results in this paper show that the sputtered NiO$_{mathbf {x}}$ can be an effective interlayer material for thin film c-Si solar cell contacts.","PeriodicalId":6558,"journal":{"name":"2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC)","volume":"26 1","pages":"2180-2182"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89520591","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}

Under real operating conditions the temperature of cells increases with environment, shades or local defects (hot spots) and electrical effects. This increase in temperature causes a decrease in the electrical parameters of solar cells, which makes the electrical power and efficiency of cell are reduced, and also affect the average life of device. Photovoltaic cells have yields between 15% and 25% but efficiency decreases with increasing temperature up to 0.3% per degree centigrade. In practical terms the thermal part of solar radiation can increase the temperature inside the cell by about 30°C, and in turn decrease the yield to unsustainable values. The objective of this research is the application of the Peltier effect to reduce the impact of temperature on the efficiency of photovoltaic cells under operating conditions. For this reason, in this work an alternative was developed to find the suitable temperature for the photovoltaic cell to reach and maintain its highest efficiency. For this, a temperature control based on thermoelectric cells or Peltier effect is used. With the results optimal operating temperatures of the photovoltaic cell are proposed that do not impact the power of the cell.","PeriodicalId":6558,"journal":{"name":"2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC)","volume":"1 1","pages":"0438-0441"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89604722","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}

Known risks of PERC cells, including light-induced degradation and passivation layer stability, are of key concern in this fastgrowing market. Here we measure performance and mechanistic parameters of bare PERC and Al-BSF cells stepwise through UV + heat exposure by ${Suns} - V_{OC}$, external quantum efficiency, and microwave photoconductive decay to obtain timeseries of mechanistic and performance variables to evaluate in our < Stress|Stress|Mechanism|Response> analytic framework. With the creation of statistical models relating these variables, individual degradation modes are determined and ranked for PERC and Al-BSF cells. By comparing PERC and Al-BSF cells, we can identify PERC-specific degradation modes and inform future mitigation strategies. In this study, PERC cells showed two significant pathways related to power loss: one via degradation of the minority carrier lifetime and diffusion/rear side recombination, and another via bulk/emitter recombination and voltage losses.","PeriodicalId":6558,"journal":{"name":"2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC)","volume":"1 1","pages":"1255-1260"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73477578","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}
