Abstract

Three nonfullerene acceptors CO5DFIC, CO5DFIC-OT and CO5DFIC-ST were developed. CO5DFIC-OT and CO5DFIC-ST have alkoxythiophene and alkylthiothiophene π-bridges, respectively, and they show higher LUMO levels and enhanced light-harvesting capability compared to CO5DFIC without π-bridges. CO5DFIC-OT and CO5DFIC-ST solar cells gave higher open-circuit voltage, short-circuit current density and power conversion efficiency than CO5DFIC cells.
