A photoelectric conversion element, a dye-sensitized solar cell, and a metal-complex pigment, pigment solution, and terpyridine compound or esterified terpyridine compound used therein. The photoelectric conversion element has an electrically-conductive support, an electrolyte-containing photoreceptor layer, an electrolyte-containing charge-transfer layer, and a counter electrode. The photoreceptor layer contains semiconductor microparticles on which a metal-complex pigment that can be represented by a specific formula (1) is supported. |
