The aluminum (5005-H34) alloy trough or housing module was anodized in a chilled (0-5 degrees C) 18% aqueous sulfuric acid bath. The entire housing was anodized to 50 V at a current density of 1.4 A/dm/sup 2/. A styrene-acrylate copolymer electrophoretic bath was prepared, and the bottom of the inside of the module was electrocoated at 0.5 mA/cm/sup 2/ for 120 s. Breakdown measurements were obtained by placing a probe on the coating composite and gradually increasing the voltage until a current in excess of 10 mA occurred. The results indicate that thin, relatively high thermal conductivity, high-voltage breakdown dielectrics can be formed using this economical process.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"5 1","pages":"1338-1340 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75992719","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}

Bare cells (i.e. with no coverglass) were exposed to several energies of electron and proton radiation, and their performances were monitored by illuminated I-V curves, dark I-V curves, and spectral response measurements at different fluence levels. These experiments reconfirm that no measurable damage occurs to CIS solar cells when exposed to 1 and 2 MeV electrons to a total fluence of 5.0*10/sup 15/ cm/sup -2/. For proton irradiations, the results indicate that CIS cells are more radiation resistant than GaAs cells, by a factor of ten, when compared at the same energy levels. Comparison of the electron and proton irradiation results to those reported in the literature shows that the thin-film GaAs solar cells are as radiation resistant as other GaAs bulk cells at 1.0 MeV protons and are more radiation resistant at both the 1.0 MeV electron and 200 keV proton energies.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"6 1","pages":"909-912 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79900969","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}

Using a model density of states, the authors conclude that it is intrinsically impossible to distinguish between Si and Ge dangling bonds. In addition, despite the fact that the density of bulk defects can be evaluated successfully, it is suggested that there is always a spurious absorption due to surface states. The measured density of dangling bonds keeps increasing from pure a-Si:H (N/sub d/ equivalent to 2*10/sup 16/ cm/sup -3/) to pure a-Ge:H (N/sub d/ equivalent to 5*10/sup 17/ cm/sup -3/), and this is shown to be a material property.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"22 1","pages":"212-217 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87149859","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}

The emphasis is on techniques that provide structural, chemical, and bonding information on atomic dimensions. Specifically, spectroscopic scanning tunneling microscopy (STM) is discussed in terms of providing complementary diagnostic information.

The use of unglassed solar cells on four of the six strings does not seem to affect these performance trends, confirming that the surrounding mirror and cell assembly components can be used as cell shielding. Analysis of current output during off-pointed periods allows a determination of concentrator pointing tolerances.
