Abstract:
1. A photoelectric conversion device, using oxide semiconductor fine particles sensitized with a methine dye represented by the following formula (1): wherein n represents an integer of 0 to 7; R X is a linking group which is combined with a nitrogen atom bonded to a benzene ring a to form a heteroring, and represents —CH Y represents a hydrogen atom, an optionally-substituted aromatic residue, an optionally-substituted aliphatic hydrocarbon residue, a carboxyl group, a phosphoric acid group, a sulfonic acid group, a cyano group, an amide group, or an alkoxycarbonyl group; Z represents an optionally-substituted aromatic residue, an optionally-substituted aliphatic hydrocarbon residue, or an acyl group; A the benzene ring a may have, as substituent(s) other than X and the nitrogen atom shown in the formula (1), 1 to 3 substituents selected from a group consisting of: halogen atoms; amide, hydroxyl, cyano, nitro, alkoxyl, acyl, and substituted or unsubstituted amino groups; and optionally-substituted aliphatic hydrocarbon residues and optionally-substituted aromatic residues, provided that when plural said substituents are plural, these substituents may be bonded with each other, thereby forming an optionally-substituted ring.
