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.
