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% (J_SC = 13.87 mA cm⁻², V_OC = 1.08 V and FF = 0.61) and a low photon energy loss of 0.52 eV.
