A highly efficient fullerene‐free polymer solar cell (PSC) based on PDCBT, a polythiophene derivative substituted with alkoxycarbonyl, achieves an impressive power conversion efficiency of 10.16%, which is the best result in PSCs based on polythiophene derivatives to date. In comparison with a poly(3‐hexylthiophene):ITIC‐based device, the photovoltaic and morphological properties of the PDCBT:ITIC‐based device are carefully investigated and interpreted.
