description

Abstract Alternative acceptor materials are possible candidates to improve the optical absorption and/or the open circuit voltage of polymer–fullerene solar cells. We studied a novel fullerene-type acceptor, DPM-12, for application in polymer–fullerene bulk heterojunction photovoltaic devices. Though DPM-12 has the identical redox potentials as methanofullerene PCBM, surprisingly high open circuit voltages in the range V OC =0.95 V were measured for OC 1 C 10 -PPV:DPM-12-based samples. The potential for photovoltaic application was studied by means of photovoltaic characterization of solar cells including current–voltage measurements and external quantum yield spectroscopy. Further studies were carried out by profiling the solar cell parameters vs. temperature and white light intensity.
