S/Ge dual gradient spontaneous construction for improved CZTSSe solar cells
Nano ResearchA key reason for Cu2ZnSn(S,Se)4 (CZTSSe, 15.8%) solar cells lagging far behind Cu(In,Ga)Se2 (CIGS, 23.6%) in efficiency is its inability to autonomously form a dual-gradient bandgap via Ga gradient, critical for the simultaneous efficient light ...

CdCl2 Treatment for Cu2ZnSn(S,Se)4: A Method to Enhance the Solar Cell Performance
Progress in Photovoltaics: Research and Applications, Volume 34, Issue 3, Page 271-285, March 2026.We present, for the first time, two alternative CdCl2 treatments applied to solution‐processed kesterite (CZTSSe) absorbers: pre‐selenization and post‐selenization. Carrier concentration is consistently increased by either route, whereas the band gap decreases with pre‐selenization but remains nearly constant with post‐selenization; enhanced defect ...
