Abstract

A new A-π-D-π-A small molecule with a Ni-porphyrin core (MV143) has been synthesized and employed as a donor, along with PC71BM, for the fabrication of solution-processed bulk heterojunction OSCs organic solar cells. The device exhibited an overall PCE of 9.14% (JSC = 13.87 mA cm-2, VOC = 1.08 V and FF = 0.61) and a low photon energy loss of 0.52 eV.
