A photoelectric conversion element, having:
an electrically-conductive support;
a photoconductor layer having a layer of semiconductor fine-particles that have adsorbed a dye;
a charge transfer layer containing an electrolyte; and
a counter electrode;
which are provided on one side of the electrically-conductive support in this order,
wherein the dye has at least one terdentate ligand having at least one acidic group; at least one ligand coordinating to a metal atom M has an sp2 carbon atom; a cyclic group binds to the sp2 carbon atom; in a circle position connecting through a carbon atom(s) from an atom of the cyclic group directly binding to the sp2 carbon atom, a substituent R is substituted at an atom of an ±-position or ²-position to the atom of the cyclic group directly binding to the sp2 carbon atom, with the substituent R being selected from a linear or branched alkyl group, a cycloalkyl group, an alkoxy group, a cycloalkoxy group, an aryloxy group, an alkylthio group, a cycloalkylthio group, an arylthio group, an amino group, an alkylamino group, a cycloalkylamino group, an arylamino group, a heterocyclic amino group, a silyl group, or a silyloxy group; and when the atom of the ±-position or ²-position to which the substituent R binds is defined as G1 and an atom of the substituent R which directly binds to the atom G1 is defined as G2, an angle ¸ (ˆ MG1G2) formed by the metal atom M, the atom G1 and the atom G2, which is centered on the atom G1, is 150° or less, a dye-sensitized solar cell, a metal complex dye, a dye solution containing the dye and a compound useful as a ligand of the dye. |
