title: A selenophenyl bridged perylene diimide dimer as an efficient solution-processable small molecule acceptor.
abstract: We report herein a new solution-processable small molecule acceptor, a selenophenyl bridged perylene diimide dimer, that gives 4.0% efficiency when employing PBDTTT-C-T as the polymer donor and a conventional cell structure.
