PHOTOELECTRIC CONVERSION MATERIAL, SEMICONDUCTOR ELECTRODE, AND PHOTOELECTRIC CONVERSION ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a photoelectric conversion element superior in photoelectric conversion characteristics.

SOLUTION: The element uses a dyestuff as shown in general formula 1 of the Fig.1 as a photoelectric conversion material. In this case, in the general formula 1, R1shows arylene group, heterocyclic ring; R2shows hydrogen atom, alkyl group, alkoxy group, halogen atom; R3, R4show hydrogen atom, alkyl group, alkoxy group, alkylthio group, mono-substituted amino group, di-substituted amino group, alalkyl group, alkenyl group, aryl group, heterocyclic ring residue; R5shows a substituted group having an acidic group; R6, R7show hydrogen atom, alkyl group, aryl group, heterocyclic ring, R8, R9, R10show hydrogen atom, alkyl group, alkoxy group, aryl group, heterocyclic ring; X1shows a linking group forming an annular structure together with amino group; and m shows an integer of 0-2, and n shows integer of 0-2 respectively. In addition, the carbon-to-carbon double bond may be any of E type or Z type.
