Provided is a photoelectric conversion device capable of improving a conversion efficiency. In a dye-sensitized photoelectric conversion device including a working electrode and a facing electrode, and an electrolyte inclusion, a dye is carried on a metal-oxide semiconductor layer of the working electrode. The dye includes cyanine dye having a benzyl group and an indolenine skeleton. Therefore, crystallization of the dye on the surface of the metal-oxide semiconductor layer is suppressed.
