The present invention provides a photoelectric conversion element and a dye-sensitized solar cell, and a metal complex dye, a dye solution, and a terpyridine compound or an esterified product thereof, the photoelectric conversion element comprising: a conductive support, including A photoreceptor layer of an electrolyte, a charge transporting body layer containing an electrolyte, and a counter electrode, and the photoreceptor layer has semiconductor fine particles carrying a metal complex dye represented by the following formula (1). Formula (1) ML1L2(X)n1n·CImYnIn the formula (1), M represents a metal ion. L1 represents a group LV represented by the following formula (LV-1) or formula (LV-2)nTridentate ligand. L2 represents a ring containing a nitrogen atom constituting a ring on M by an isolated electron pair having an organic group RVLn:-(RVLn)nVLnAnd a double or tridentate ligand located on M by an anion. X represents a single tooth ligand, and n1 represents 0 or 1. CI represents the desired counter ion, and mY represents an integer from 0 to 3. □, RV1nAnd RV2nIndependently represent nitrogen atoms or CRV4n, RV4nRepresents a hydrogen atom or a substituent. RV3nRepresents an aryl or heteroaryl group. RVLnRepresents a specific aromatic ring group, etc., nVLnAn integer representing 0 or more. |
