In particular, the aim of this work is to analyze the variation of the solar cells remaining factors due to neutron irradiation with respect to those previously obtained with electrons and protons. The current analysis confirms that the degradation of the Pmax electrical parameter is related by means of the usual semi-empirical expression to the displacement dose, independently of type of the incoming particle. Isc and Voc parameters were also measured as a function of the displacement damage dose.

The design of such processes is facilitated by accurate calibrations of Cu and In<inf>2</inf>Se<inf>3</inf> growth rates on substrate/film surfaces obtained by real time spectroscopic ellipsometry (RTSE). The two-stage deposited CIS films were also studied by RTSE to deduce (i) the evolution of film structure upon conversion of the starting In<inf>2</inf>Se<inf>3</inf> or Cu<inf>2-x</inf>Se films to CIS via Cu+Se or In+Se co-evaporation, respectively, and (ii) the complex dielectric functions of the starting films as well as the resulting CIS.

Results indicate that by depositing Cu<inf>2-x</inf>Se in the first stage and exposing the film to In+Se flux in the second stage [as in the third stage of a three-stage CIS process] well-defined bandgap critical points with no detectable subgap absorption are noted in films as thin as 650 Å.","PeriodicalId":6749,"journal":{"name":"2019 IEEE 46th Photovoltaic Specialists Conference (PVSC)","volume":"1 1","pages":"0943-0948"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85459694","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 report a detailed study of electrical properties of ZnMgO (ZMO)/CdTe and cadmium sulfide (CdS)/CdTe solar cells with the cadmium chloride (CdCl2) treatment performed in different atmospheres using temperature-dependent impedance spectroscopy and capacitance – voltage measurements. An equivalent circuit model consisting of two serial combinations of the front and back junctions is employed to fit the complex impedance spectra of devices measured in dark. Fitted data from equivalent circuit provides the value of each element, from which the bulk conductivity, back contact barrier height, as well as spatial inhomogeneities within the cell are extracted. Impedance spectroscopy analysis shows that there are negative and positive effects of back surface treatment in oxygen free ambient on device performance. For oxygen-free treatment, an obvious increase in the bulk conductivity is observed, suggesting an increased copper doping in the device. Additionally, ZMO devices show less junction inhomogeneity. All these improvements lead to better device performance of ZMO/CdTe solar cells.","PeriodicalId":6749,"journal":{"name":"2019 IEEE 46th Photovoltaic Specialists Conference (PVSC)","volume":"39 1","pages":"0177-0181"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85689107","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}

Degradation of each module has been investigated in terms of degradation of short-circuit current (ISC), open-circuit voltage (VOC), fill factor (FF) and maximum power (PMPP). The analysis for the period of monitoring data from 2014 to 2018 show no considerable module degradation compared to the standard degradation rate of all parameters. The statistical analysis of ISC shows an average degradation of 0.17% for all modules. Spectral corrections were applied to ISC and PMPP, in addition to temperature and irradiance corrections. Among the parameters, FF and ISC show slight degradation based on the yearly average method. Infrared images were used for validation of findings, but due to the unavailability of images from the initial installation period, the image results are inconclusive. Performance ratio plots based on corrected ISC values show very stable performances over the five-year period. The results suggest that PV modules in cold conditions may undergo lower degradation compared to typical degradation rates experienced in other regions.","PeriodicalId":6749,"journal":{"name":"2019 IEEE 46th Photovoltaic Specialists Conference (PVSC)","volume":"99 1","pages":"1377-1383"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85774623","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}
