The effects of ZnSe with thicknesses between 200 AA and 2000 AA and ZnSe deposition temperatures between 100 degrees C and 200 degrees C were investigated. For the CdS:In/CdS/ZnSe/CuInSe/sub 2/ cells, as the ZnSe thickness increases, J/sub 0/ decreases and/or the diode factor A increases. For the In/sub 2/O/sub 3//ZnSe/CuInSe/sub 2/ cells the change of J/sub 0/ is much less and there is an increase in the diode factor for increasing ZnSe thickness. Under illumination, the V/sub oc/ of the cell is the same with and without ZnSe and the cells with ZnSe layers thicker than 400 AA show strong photosuppression.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"58 1","pages":"1431-1436 vol.2"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86888373","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}

Two peaks in the density of states at 0.6 and 0.38 eV below E/sub c/ were detected. Upon light soaking the peaks of shallow states were quenched and the peaks of deep states were enhanced; the original distribution was restored by annealing above 120 degrees C. The formation and annealing kinetics of the deep states were studied. A power law was obtained for the formation. Activation energies for annealing were centered around 1.1 eV, and a correlation of the activation energies with the energetic position of defects in the gap was obtained. To explain the results, a model of the defect structure involving charged and neutral Si defects in different hybridization states is discussed.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"70 1","pages":"154-159 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86256698","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 best performance of these tandem cells achieved so far is 21.3% AM0, one sun, for a 1 cm/sup 2/ four-terminal device at 28 degrees C. A GaAs subcell efficiency of 18.8% and a CuInSe/sub 2/ subcell efficiency of 2.5% were measured for this device. Top cell efficiency up to 19.5% and lower cell efficiency up to 2.83% were measured for other tandem cells. A 3.0% CIS cell was achieved using a GaAs filter with a glycerol optical matching medium. This demonstrated efficiency provides for specific powers up to 620 W/kg when 50 mu m thick substrate and cover glasses are incorporated. Favorable results were obtained from thermal cycling experiments conducted to evaluate survivability of thin GaAs films in adhesive/glass sandwich structures.<<ETX>>","PeriodicalId":10562,"journal":{"name":"Conference Record of the Twentieth IEEE Photovoltaic Specialists Conference","volume":"49 1","pages":"457-461 vol.1"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88883848","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}

Analysis of flight data indicates that the performance of the four cells throughout the first year is near expected values. No degradation in short-circuit current was seen, as was expected from radiation tolerance studies of similar cells. Details of the cell structure and flight module design are discussed.
