Abstract

A cation substitution in Cu 2 ZnSn(S,Se) 4 (CZTSSe) offers a viable strategy to reduce the open-circuit voltage ( V oc )-deficit by altering the characteristics of band-tail states, antisite defects, and related defect clusters. Herein, we report a facile single process, i.e., simply introducing a t...
