Abstract

Efficiency of 12.3% on solution-based CU2ZnSn(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 CU2ZnSnS4 (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.
