(57) [Problem] To provide a dye-sensitized photoelectric conversion element which is inexpensive and has high conversion efficiency. A photoelectric conversion element and a photovoltaic cell using semiconductor fine particles sensitized by a dye represented by the following general formula (I) or (II). Embedded image (Z and Z ′ represent a single bond or an atomic group necessary to complete a 5- to 9-membered ring, and the atomic group is constituted by atoms selected from H, C, O, N, and S. L 1 ~L 5 represents a nitrogen atom or a methine group, n1 represents an integer of 0 to 2. n2 represents the integer of 0-4. V represents an amino group or an alkoxy group, and V may form a ring together with the benzene ring substituted by V. A and A 'represent a substituent, and may be condensed with the substituted benzene ring. Q represents a group of atoms necessary for completing a 5- or 6-membered heterocyclic ring together with a nitrogen atom. R represents an alkyl group. ) |
