Abstract:The advent of non‐fullerene acceptors (NFAs) has greatly improved the photovoltaic performance of organic solar cells (OSCs). However, to compete with other solar cell technologies, there is a pressing need for accelerated research and development of improved NFAs as well as their compatible wide bandgap polymer donors. In this study, a novel electron‐withdrawing building block, succinimide‐substituted thiophene (TS), is utilized for the first time to synthesize three wide bandgap polymer donors: PBDT‐TS‐C5, P… Show more
