All-inorganic Sb2S3-based two-terminal tandem solar cells enable over 10.9% efficiency employing a concise interconnection layer

Sb 2 S 3 -based two terminal tandem solar cells (2T-TSCs) are reported for the first time with the assistance of lead sulfide quantum dot rear cells. The PCE of the champion TSC reaches 10.92%. Our work opens the door for Sb 2 S 3 based 2T-TSCs.
