The present invention provides a photoelectric conversion device that has enhanced photoelectric conversion characteristics and durability, and the like. In a photoelectric conversion device comprising a working electrode having a dye-supported metal oxide electrode in which a dye is supported on a metal oxide layer, a dye having a structure represented by the following general formula (I) is used. wherein A is a structure having a maximum absorption wavelength »max of 350 to 500 nm in a methanol solution; B is a cyanine skeleton having a maximum absorption wavelength »max of 500 to 700 nm in a methanol solution; Z 1 is any one divalent linking group selected from -CONR-, -NRCO-, -SO 2 NR-, and -NRSO 2 -; R in Z 1 is a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, or an arylalkyl group having 7 to 20 carbon atoms; Y 1 and Y 2 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.
