We demonstrated a new synthetic approach to prepare Cu2ZnSn(S1−xSex)4 nanocrystals with various S/Se ratios (x = 0, 0.2, 0.5, 0.85, and 1). LSV and EIS studies also revealed that the electron transfer kinetics and diffusion resistance of electrolyte were dictated by the S/Se ratios. In our study, the QDSSC with CZTSSe (x = 0.5) CE showed the highest energy conversion efficiency of 3.01%, which was higher than that (1.24%) obtained using Pt CE.
