A series of symmetrically substituted subphthalocyanine derivatives with diverse substituent such as electron-donating or electron-withdrawing moieties at the peripheral position have been synthesized and their photophysical and electrochemical properties have been investigated. Solution-processed bulk heterojunction (BHJ) organic solar cells using SubPc derivatives as electron donor and fullerene derivative PCBM as an electron acceptor in the active layer were fabricated and characterized to evaluate the photovoltaic behavior of these molecules.

Four solution-processable D-A-D structured organic molecules with diketopyrrolopyrrole (DPP) as acceptor unit and triphenylamine (TPA) or (4-hexyl)thieno [3,2-b]thiophene (HTT) as donor unit, DPP8-TPA, DPP8-TPA-OR, DPP6-HTT and DPP8-HTT, were designed and synthesized for the application as donor materials in solution-processed organic solar cells (OSCs). The molecules show broad absorption and relatively lower highest occupied molecular orbital energy levels. Photovoltaic properties of the molecules were investigated by fabricating the bulk-heterojunction OSCs with the molecules as donor and PC 71 BM as acceptor. Power conversion efficiency of the OSC based on DPP8-HTT reached 1.5% under the illumination of AM1.5, 100 mW cm −2 .
