Over 12% efficiency Cu 2 ZnSn(SeS) 4 solar cell via hybrid buffer layer


Journal Article

© 2014 IEEE. Efficiency of 12.3% on solution-based Cu 2 ZnSn(SeS) 4 (CZTSeS) solar cells was achieved by applying hybrid buffer layer with combination of In-based buffer and Cd-based buffer layers. Previously, the V oc boost by the hybrid buffer layer on Cu 2 ZnSnS 4 (CZTS) and CZTSeS solar cells have been reported[1-2]. In this paper, the latest results and some analyses of the hybrid buffer for solution-based CZTSeS cells will be presented.
