The cells are mounted on a rocker during irradiation, to simulate hemispherical isotropic radiation. Data from ITO/InP cells are compared to those for commercially available GaAs and Si cells irradiated under the same conditions. At all proton energies, the ITO/InP cells showed a significantly lower percentage of degradation than the other types of cell. It is concluded that the two types of cell operate in a similar manner. From the data, the ITO/InP structure appears to present the same advantages with respect to radiation resistance as does the homojunction structure.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"59 1","pages":"898-902 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76482287","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}

It is noted that there is a growing interest in lightweight concentrator arrays with high levels of radiation resistance for orbital applications, and in a totally new generation of solar array technology for terrestrial-like applications in a nonterrestrial environment. Also considered is the advanced development of photovoltaic power systems for operation on the Lunar and/or Martian surface. This new scenario makes it possible for the terrestrial thin-film technologies to compete effectively with the high-efficiency solar cell technology that traditionally has been pursued in the space program. It is concluded that present and near-future US Air Force and NASA requirements show needs that, if the problems are looked upon as opportunities, can elevate the photovoltaic power source scientist and array structure engineer into the next technological photovoltaic growth curve.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"116 1","pages":"8-20 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85241375","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}

High-efficiency cells with total-area efficiencies greater than 20% at AM 1.5 and 18% at AM0 have been successfully fabricated. It is demonstrated that InP cells have more radiation resistance than Si or GaAs solar cells. The superior radiation tolerance of InP cells is concluded to be due to the lower migration energies of radiation-defects in InP compared to those in GaAs. The results show that InP cells have great potential for space power applications.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"26 1","pages":"880-885 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84073895","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}
