摘要

•A low-cost and non-toxic AlCl3 solution treatment is applied to improve the efficiency of the CCZTS solar cells up to 11.10%.•The band alignment at grain boundaries of CCZTS films was characterized by conducting-AFM.•A new direction for optimizing the solar cells performance with band alignment engineering is demonstrated.
