PROBLEM TO BE SOLVED: To provide: a photoelectric conversion element improved in spectral sensitivity characteristics in a long wavelength region and excellent in photoelectric conversion efficiency and durability; a dye-sensitized solar cell; a metal complex dye, a dye solution and a dye-adsorbed electrode which are used for the dye-sensitized solar cell; and a method for manufacturing a dye-sensitized solar cell.SOLUTION: A photoelectric conversion element includes a conductive support 1, a photosensitive layer 2 containing an electrolyte, a charge transfer layer 3 containing an electrolyte and a counter electrode 4. The photosensitive layer 2 includes fine semiconductor particles 22 that support a metal complex dye 21 represented by M(LD)(LA)-(CI) [where, M represents a metal ion, LD represents a tridentate ligand represented by formulae (DL-1)-(DL-4), LA represents a specific tridentate ligand, and CI represents a counter ion for neutralizing an electrical charge (each of Yand Yrepresents O, S, a substituted or unsubstituted N, or a substituted or unsubstituted P; and each of ring AD and ring BD represents a hydrocarbon ring or a hetero ring, and L represents a linking group)]. |
