A novel isomer of pyrrolo[3,4-c]pyrrole-1,4 (2H,5H)-dione as a new building block for polymer solar cells

•Four novel copolymers containing pyrrolo[3,4-c]pyrrole-1,4-dione were synthesized.•The novel iso-DPP copolymers showed promising photovoltaic properties.•P1 showed a band gap of 1.63eV and slightly deeper HOMO level (−5.12eV).•P1-based photovoltaic devices showed a power conversion efficiency up to...
