ABSTRACT:
The present invention provides: an organic compound increasing an open circuit voltage, and showing high photoelectric conversion efficiency; a semiconductor film electrode employing the organic compound as a dye; a photoelectric conversion element employing the semiconductor film electrode; and a photoelectrochemical solar cell employing the photoelectric conversion element. The organic compound is represented by the following general formula:wherein A is a carbazole ring; L1is an electron transfer linking group having at least one heterocyclic ring selected from the group consisting of a thiophene ring, a furan ring, a pyrrole ring, and a condensed heterocyclic ring formed from any combinations of these rings; R is a substituent group bound to at least one electron transfer linking group selected from the group consisting of an alkyl group, an alkoxy group, and an aryl group; X is at least one electron withdrawing group selected from the group consisting of a cyano group, a carboxylic acid group, an ester group, an amide group, a trifluoromethyl group, a pentafluoroethyl group, a sulfonate group, and a trifluoromethanesulfonate group; M is a hydrogen atom or a salt-forming cation; and n is an integer of 1 to 12.
