Abstract

A low bandgap polymer acceptor PF5-Y5 was synthesized and its all-PSCs achieved an impressive device efficiency of 14.45% with both high <italic>V</italic><sub>oc</sub> and <italic>J</italic><sub>sc</sub> due to the excellent absorption coverage, small energy loss, and efficient charge separation.
