Abstract
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 bonded to 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 …
