Growth and Device Characteristics of CZTSSe Thin-Film Solar Cells with 8.03% Efficiency

24.07.2015 | Dae-Ho Son; Dae-Hwan Kim; Si-Nae Park; Kee-Jeong Yang; Dahyun Nam; Hyeonsik Cheong; Jin-Kyu Kang, Chemistry of Materials, 2015

The improvement of the efficiency of Cu2ZnSn(S,Se)4 (CZTSSe)-based solar cells requires the formation of high-grain-sized pure CZTSSe throughout the film. We have successfully selenized precursor samples of Cu/SnS/ZnS/Mo/Soda lime glass in an almost sealed selenium furnace. Owing to the presence ...
