The progress in crystalline silicon technology has manifested itself in improved efficiency and in lower costs of processing and production. Experience over the past eight years with large systems representative of utility-scale applications has been good. It is suggested that there now appear to be several choices within the crystalline silicon technology path that have excellent potential to meet the necessary cost for entry into the utility market. The status of the current research efforts and the direction of the US Department of Energy sponsored crystalline silicon research program are discussed.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"7 1","pages":"397-404 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89208357","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 internal collection efficiency is shown to be a function of wavelength and voltage. The function shows a certain kind of symmetry that is not perfect, but reveals a plateau voltage U/sub p/. A simple photocurrent model is used to explain the experimental results. The model assumes a uniform field through the i-layer. It neglects bulk recombination of photocarriers, but considers surface recombination at the p-i and i-n barriers. A particular voltage, the flatband voltage U/sub F/, causes the field to vanish. A dominant front barrier yields U/sub p/<U/sub F/.

The solar arrays on GPS Navstars 1-6 have shown anomalous degradation during the 5-year mission life and beyond. The departure from predicted performance consists of an extra 2.5% per year degradation in excess of the radiation model estimates. Examination of optical solar reflector (OSR) data from a variety of spacecraft reveals variations in OSR degradation rates which correlate with the vehicle design. These data support the idea that contaminants outgassing from the vehicle are photodeposited on the optical surfaces, leading to degradation of their reflectivity. Contamination data taken from an OSR flown on Navstar 5 are used to predict the solar cell array degradation. The predicted effect of contamination on the array output is consistent with the observed behavior of the five Block I vehicles.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"21 1","pages":"913-917"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86191211","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}

Starting with space debris and meteoroid flux models, the: (i) projected surface area of the solar cell string circuit of the solar array panel and the mast longeron; (ii) the design lifetime; and (iii) the probability of no impact on the solar mast and solar cell string circuits are determined as a function of particle size. The probability of no impact on the cell string circuits is used to derive the probability of no open-circuit panel. The probability of meeting a certain power requirement at the end of the design lifetime is then calculated as a function of impacting particle size. Coupled with a penetration and damage model correlation that relates the particle size to penetration depth and damage, the results of this analysis can be used to determine the probability of meeting the power requirements, given a degree of redundancy.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"73 1","pages":"868-873 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82878761","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 analysis is applied to Pacific Gas and Electric Company's system. Two basic questions are addressed. First, Which is of greatest value to PG&E: a large PV plant or several small plants distributed throughout the system? Second, Where should the plant or plants be sited? The value calculations use simulated performance data based on data from PG&E's solar insolation monitoring project (SIMP). Fourteen representative sites throughout PG&E's service territory are evaluated in order to select the site or configuration of sites with the highest value. The results lead to the conclusion that, all else being equal, the highest value is provided by one large PV plant rather than a combination of several smaller plants distributed throughout the service territory.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"65 1","pages":"1056-1061 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84428052","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}
