Photoelectric conversion element and solar cell

A dye-sensitizing type photoelectric conversion element comprising a pair of facing electrodes, a semiconductor layer comprising a semiconductor and a sensitizing dye supported on the semiconductor, and a charge transport layer,

• wherein the semiconductor layer and the charge transport layer are provided between the facing electrodes, and
• wherein the sensitizing dye comprises a compound represented by the following Formula (1)
• where Ar represents a substituted or unsubstituted arylene group or heterocylic group;
• each of R1 and R2 represents a substituted or unsubstituted alkyl group, alkenyl group, alkynyl group, aryl group or heterocyclic group;
• R1, R2 and Ar may form a cyclic structure via connection to each other;
• R3 represents a hydrogen atom, a halogen atom, a cyano a substituted or unsubstituted alkyl group, an alkenyl group, an alkynyl group, an alkoxy group, an amino group, an aryl group or a heterocyclic group;
• R4 represents a hydrogen atom, a substituted or unsubstituted alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group;
• R5 represents an alkyl group, an alkenyl group, an alkynyl group, an alkoxy group, an alkylthio group, an alkylseleno group, an amino group, an aryl group or a heterocyclic group, which is substituted by X, but R5 may have a substituent other than X;
• X represents an acidic group;
• m is an integer of at least 1;
• in the case of m≧2, X may be the same or different;
• and a carbon-carbon double bond may be a cis type double bond or a trans type double bond.
