A new low band gap small molecule DPP–DTF with a D–π–A–π–D molecular structure composed of a dithiafulvalene (DTF) donor and a diketopyrrolopyrrole (DPP) acceptor was synthesized and tested for organic solar cells.
Soluble co-polymers of the fused selenophene monomer, DSG, with N-octylthienopyrrolodione are reported. Polymer solar cells fabricated from blends with PC71BM exhibit promising performance in inverted bulk heterojunction solar cells
