Perovskite Materials and Applications

A novel D–A-π-A type organic dye (YCD01) incorporating a diketopyrrolopyrrole unit with a branched alkyl chain was synthesized for dye-sensitized solar cells. YCD01 showed a high conversion efficiency of 7.43% (AM 1.5, 100 mW cm−2) with a Jsc of 13.40 mA cm−2, a Voc of 0.76 V, a FF of 0.73 and an excellent stability.
