Abstract

We report three novel heteroleptic ruthenium complexes, RD1: Ru[(dcbpy)(1-methyl-2-(pyridin-2-yl)-1H-benzimidazole)(NCS)2, RD2: Ru [(dcbpy) (2-(pyridine-2-yl) benzothiazole) (NCS)2, and RD3: Ru[(dcbpy)(2-(pyridin-2-yl) benzoxazole) (NCS)2, for dye-sensitized solar cell applications. We found that RD1 exhibits a dye loading amount two times higher than that of N719, which gives a broad IPCE action spectrum for the spectral response beyond 800 nm. This series of dyes can be easily synthesized in three steps with the best dye (RD1) reaching 80 % cell performance of N719.
