(57) [Problem] To provide a metal complex dye capable of efficiently sensitizing semiconductor fine particles using light having a wavelength of 800 nm or more, and a photoelectric conversion element exhibiting high conversion efficiency by using the metal complex dye. . SOLUTION: A photoelectric conversion element comprising semiconductor fine particles sensitized by a metal complex dye containing a ligand represented by the following general formula (I). Embedded image However, in the general formula (I), n is 0 or 1, and R 1 to R 3 independently represent a substituent. m1~m3 represents an integer of 0 to 3, when the m1~m3 is 2 or more, R 1 each other, R 2 to each other, or different R 3 together are the same, respectively, form a ring with each other May be. V 1 to V 3 independently represent hydrogen or a substituent, and at least one of V 1 and V 2 is represented by the following general formula (II). Embedded image In the general formula (II), L 1 and L 2 are each a substituted or unsubstituted methine group, and 1 represents an integer of 1 to 5. V 4 is a carboxyl group, a sulfonic acid group, a phosphonic acid group, a phosphoric acid group, a silicic acid group, a boric acid group, a hydroxyl group, a squaric acid group or a proton dissociated product thereof. |
