Seleno twisted benzodiperylenediimides (TBDPDI-Se) as promising electron acceptor chromophores were designed and synthesized using a facile strategy with which different side chains could be introduced readily. Bulk heterojunction organic solar cells based on these acceptors exhibit the highest power conversion efficiency of 7.41% without any additive treatment.
