Summary: | A photoelectric conversion device capable of improving conversion efficiency is provided. The photoelectric conversion device includes a work electrode 10, a counter electrode 20, and an electrolyte-containing layer 30. In the work electrode 10, a metal oxide semiconductor layer 12 supporting a dye 13 is provided. The dye 13 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 13, electron injection efficiency to the metal oxide semiconductor layer 12 is improved. |
