Abstract

A new benzodithiophene-based copolymer PTG1 with dithienylbenzothiadiazole–vinylene side chains exhibits excellent film-forming ability, a deep HOMO energy level, and a good miscibility with PC71BM. Bulk heterojunction polymer solar cells fabricated from PTG1 and PC71BM showed a promising power conversion efficiency over 4.0%.
