PHOTOELECTRIC CONVERSION ELEMENT, PHOTOELECTROCHEMICAL CELL, AND DYE USED IN PHOTOELECTRIC CONVERSION ELEMENT AND PHOTOELECTROCHEMICAL CELL

摘要

A photoelectric conversion element which has a laminated structure wherein a photosensitive body having a semiconductor particle layer onto which a dye is adsorbed, a charge transfer body and a counter electrode are arranged on a conductive supporting body. In this photoelectric conversion element, a metal complex dye represented by formula (1) is used as the dye. ML1L2X (1) (In the formula, M represents a transition metal selected from among ruthenium, osmium, iron, rhenium and technetium; X represents NCS-, Cl-, Br-, I-, CN-, NCO-, H2O or NCN2 -; L1 represents a specific tridentate ligand; and L2 represents a specific bidentate ligand.)
