Owing to the small size of the lens array, the total track of the CPV system can be as small as 4 cm. Consquently, the weight of the CPV system can be much lower than conventional bulky CPV system. For harvesting the diffuse solar radiation, perovskite solar cells are mounted adjacent to III-V solar cell. Theoretically, the optical efficiency can be enhanced from 70 % to 76% for γ = 0.7 In the future, we will experimentally integrate III-V solar chip with perovskite solar cell to harvest both direct and diffuse solar light, respectively. The solar conversion efficiency will be discussed as well.","PeriodicalId":123743,"journal":{"name":"2017 22nd Microoptics Conference (MOC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126378381","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}
