Abstract
A photoelectric conversion device capable of improving conversion efficiency is provided. The photoelectric conversion device includes a work electrode, a counter 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. The cyanine compound has heterocyclic skeletons containing indolenine skeletons bonded with both ends of a methine chain, an anchor group introduced to a nitrogen atom contained in the indolenine skeletons, and a phenanthrene skeleton contained in one of the heterocyclic skeletons. In the case where light enters the dye, electron injection efficiency to the metal oxide semiconductor layer is improved.
