•A donor molecule DRCN7T-Se containing selenophene as the central block was designed and synthesized.•A power conversion efficiency of 8.30% was achieved based on DRCN7T-Se/PC71BM device.•A fiber-like domains with a diameters around 20 nm was found for DRCN7T-Se/PC71BM blends under the best annealing condition.
A solution-processable A–D–A structure small molecule donor material called DRCN7T-Se with selenophene as the central block was synthesized. Conventional bulk-heterojunction solar cell devices based on DRCN7T-Se and PC71BM were optimized by thermal annealing and an excellent power conversion efficiency of 8.30% was achieved under AM 1.5G irradiation (100 mW cm−2).
