Abstract
A photoelectric conversion device capable of improving conversion efficiency is provided. The photoelectric conversion device includes a work electrode, an opposed electrode, and an electrolyte-containing layer. In the work electrode, a metal oxide semiconductor layer supporting a dye is provided. The dye contains a cyanine compound that has a methine chain, an indolenine skeleton bonded with both ends of the methine chain, and anchor groups introduced to a nitrogen atom included in the indolenine skeleton. Electron injection efficiency to the metal oxide semiconductor layer is improved, and the dye is hardly exfoliated from the metal oxide semiconductor layer.
