Abstract
The photoelectric conversion device described herein includes a working electrode having a dye-supported metal oxide electrode in which a dye is supported on a metal oxide layer. The dye includes a structure represented by general formula (I)wherein A is a structure having a maximum absorption wavelength λmax of 350 to 500 nm in a methanol solution; B is a cyanine skeleton having a maximum absorption wavelength λmax of 500 to 700 nm in a methanol solution; Z1 is any one divalent linking group selected from —CONR—, —NRCO—, —SO2NR—, and —NRSO2—; R in Z1 is a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, or an arylalkyl group having 7 to 20 carbon atoms; Y1 and Y2 are each independently an alkylene group having 1 to 8 carbon atoms, or a single bond, and may be the same or different; r is 1 or 2; m and n are each independently an integer of 0 to 2; and (m+n) is 1 or more.
