Li-TFA modulated Li-Sb dual-cation synergy enables efficient and mechanically stable flexible CZTSSe Solar Cells

Flexible kesterite Cu 2 ZnSn(S,Se) 4 (CZTSSe) thin film solar cells inherently suffer from defect-dominated carrier recombination and poor mechanical flexibility durability. Herein, a Li-TFA-assisted Li-Sb co-doping strategy is proposed for the regulation of various defects. Sb p...
