The European Patent Office (EPO), the United States Patent and Trademark Office (USPTO), the Japanese Patent Office (JPO), and the World Intellectual Property Organization (WIPO) become the main tools for emerging solar cells analysis. In total, 5027 patents related to organic solar cell and 1764 patents related to perovskite solar cell were analyzed and then sorted in thematic subcategories.

ETCs are triangular cross-section silver fingers that redirect light to the active area of the solar cell and therefore, mitigate finger grid shading losses. Furthermore, ETCs can be spaced densely leading to light trapping. We used a combination of thin film and ray optical simulations and determined that light absorption can be increased by more than 4.5% compared to state-of-the-art metallization due to light trapping and effective transparency. Furthermore, we calculated that grid resistance and silver usage can be improved when using ETCs.","PeriodicalId":6558,"journal":{"name":"2018 IEEE 7th World Conference on Photovoltaic Energy Conversion (WCPEC) (A Joint Conference of 45th IEEE PVSC, 28th PVSEC & 34th EU PVSEC)","volume":"4 1","pages":"0045-0048"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77464243","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}
