A 7.3% efficiency non–fullerene polymer solar cell is realized by combining a large‐bandgap polymer PffT2‐FTAZ‐2DT with a small‐bandgap acceptor IEIC. The complementary absorption of donor polymer and small‐molecule acceptor is responsible for the high‐performance of the solar‐cell device. This work provides important guidance to improve the performance of non‐fullerene polymer solar cells.
