A
photoelectric conversion element having a pair of electrodes, and a
semiconductor layer comprising a
semiconductor carrying a dye and an
electrolyte layer is disclosed. The dye is represented by Formulas 1 or 2;in Formula 1, Ar1 and Ar2 are each an
arylene or heterocyclic group, or a composite group of an
arylene group and a heterocyclic group, each of which may have a
substituent, Ar3 is an
aryl or heterocyclic group or a composite group of an
arylene group and a heterocyclic group, each of which may have a
substituent, Ar1, Ar2 and Ar3 may form a ring by bonding with each other, X1 and X2 are each a
straight chain residue having an acidic group which may have a mono-valent
substituent, and one to eight saturated or unsaturated
aliphatic hydrocarbon group having 5 to 30 carbon atoms are contained among Ar1, Ar2 and Ar3;in the formula, Ar11, Ar12, Ar13, Ar14 and Ar15 are each an arylene or heterocyclic group, or a composite group of an arylene group and a heterocyclic group, each of which may have a substituent, Ar11, Ar12, Ar13, Ar14 and Ar15 may form a ring by bonding with together, at least two of X11, X12, X13 and X14 are each an
alkyl or alkenyl group having an acidic group which may have a mono-valent substituent and the remainders are each a
hydrogen atom, and one to eight saturated or unsaturated
aliphatic hydrocarbon group having 5 to 30 carbon atoms are contained among Ar11, Ar12, Ar13, Ar14 and Ar15.
