A ternary conjugated D–A copolymer yields over 9.0% efficiency in organic solar cells†
Abstract
Ternary conjugated D–A copolymers are designed and synthesized by using indenothiophene and benzodithiophene as the weak and the strong donors, respectively, and fluorinated benzodithiazole as the strong acceptor. The best performance copolymer delivers a high PCE of 9.08%, which is a record efficiency for ternary conjugated D–A copolymers reported to date.
