Abstract

We report the preparation of a new acceptor unit, 3-alkoxy-4-cyanothiophene, and a 3-alkoxy-4-cyanothiophene-based low band-gap polymer (PBDT–CT) with a deep HOMO energy level (−5.5 eV). A bulk heterojunction solar cell containing PBDT–CT and PC61BM was found to exhibit a high open circuit voltage (Voc) of 0.90 V and an efficiency of 3.36%.
