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.
本文提供了一种能够提高转换效率的光电转换装置。该光电转换装置包括工作电极 10、对电极 20 和含电解质层 30。在工作电极 10 中,有一个支撑染料 13 的金属氧化物半导体层 12。染料 13 含有一种氰化合物。氰基化合物具有杂环骨架,杂环骨架包含与甲基链两端键合的吲哚啉骨架、引入到吲哚啉骨架所含氮原子上的锚基团,以及杂环骨架之一所包含的菲骨架。在光线进入染料 13 的情况下,金属氧化物半导体层 12 的电子注入效率得到提高。
