NOVELTY - A photoelectric transducer has a semiconductor oxide particles thin film in which a specific methine dye is supported, provided on a substrate.    USE - For solar cell (claimed).    ADVANTAGE - The photoelectric transducer has high photoelectric conversion efficiency.    DETAILED DESCRIPTION - A photoelectric transducer has a semiconductor oxide particles thin film in which a methine dye of formula (1) is supported, provided on a substrate.    n,m=0-5;    R1-R4=hydrogen atom, aromatic residue optionally having substituent, or aliphatic hydrocarbon optionally having substituent;    X,Y'=hydrogen atom, optionally substituted aromatic residue, optionally substituted aliphatic hydrocarbon residue, carboxyl group, phosphoric acid group, sulfonic acid group, cyano group, acyl, amide group or alkoxy carbonyl group, and X and Y' optionally couples together to form ring optionally having substituent;    Z=oxygen atom, sulfur atom, selenium atom or NR5;    R5=same as R1-R4;and    A1-A5=hydrogen atom, optionally substituted aromatic residue, optionally substituted aliphatic hydrocarbon, hydroxyl, phosphoric acid group, cyano group, halogen atom, carboxyl, carbonamide group, optionally substituted alkoxyl, optionally substituted aryloxy, optionally substituted alkoxyl carbonyl, optionally substituted aryl carbonyl or acyl.    A1, A2 and/or A3 optionally forms a ring optionally having substituent with benzene ring (a). A4 and/or A5 optionally form a ring optionally having substituent with benzene ring (a). Benzene ring (a) optionally have 1-4 substituents (S) chosen from optionally substituted aromatic residue, optionally substituted aliphatic hydrocarbon residue, hydroxyl, phosphoric acid group, cyano group, nitro group, halogen atom, carboxyl group, carbonamide group, alkoxy carbonyl group, aryl carbonyl, alkoxyl, aryloxy, amide, acetamide group, acyl and (un)substituted amino group. Substituents on benzene ring optionally combines with each other, or optionally couples with A1-A3 or A4-A5 to form ring optionally having substituent. Benzene ring (b) optionally has 1-3 substituents (S). Benzene ring (c) optionally has 1-4 substituents (S). The methine dye does not contain combination in which n is 0, m is 1, R1-R4 is methyl, Z is sulfur atom, X is carboxyl group, Y' is cyano group, A1, A4, A5 are hydrogen atom and benzene rings (a-c) are unsubstituted rings.
