The present invention relates to photoelectric conversion devices, characterized by using oxide semiconductor particles sensitized with a methine dye represented by the Formula (1):
(KA 1)
(in the Formula (1), m represents 1 to 4; n1 represents 1 to 7; p1 represents 1 to 4; X1 represents an optionally substituted aromatic residue, an optionally substituted aliphatic hydrocarbon residue, a cyano group, a phosphoric acid group, a sulfonic acid group, or a carboxyl group, a carbonamide group, and the like; L1 represents an optionally substituted aromatic residue and the like; A1 and A2 each independently represent an optionally substituted aromatic residue, a hydroxyl group, a phosphoric acid group, a cyano group, a hydrogen atom, a halogen atom and the like; the ring a1 has 1 or a plurality of halogen atoms, amide groups, hydroxyl groups, cyano groups, nitro groups, alkoxy groups, acyl groups and the like.), and solar cells made by using the same. The devices and the cells are characterized by relatively low cost, high stability, and high photoelectric conversion efficiency.
