The wall plug efficiency of ZnTe LED has been improved to 0.15% by adopting a thin film structure, which is comparable to that of GaP-based green LED. The solar cell based on ZnTe with an efficiency of 1.42% has also been developed. The fundamental results on ZnTe solar cell provide a basis for future development of intermediate band solar cells based on ZnTe-related materials.","PeriodicalId":6442,"journal":{"name":"2012 Conference on Lasers and Electro-Optics (CLEO)","volume":"23 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2012-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80977979","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}
