A small molecule named DR3TSBDT with dialkylthiol-substituted benzo[1,2-b:4,5-b鈥瞉dithiophene (BDT) as the central unit was designed and synthesized for solution-processed bulk-heterojunction solar cells. A notable power conversion efficiency of 9.95% (certified 9.938%) has been achieved under AM 1.5G irradiation (100 mW cm^鈥?), with an average PCE of 9.60% based on 50 devices.
