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