Aiming at a large open-circuit voltage (V OC) deficit in Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cells, a new and effective strategy to simultaneously regulate the back interface and restrain bulk defects of CZTSSe absorbers is developed by directly introducing a thin GeO 2 layer on Mo substrates. Power conversion efficiency (power-to-efficiency) as high as 13.14% with
