METAL COMPLEX DYE, PHOTOELECTRIC CONVERSION ELEMENT, DYE-SENSITIZED SOLAR CELL, DYE ADSORPTION LIQUID COMPOSITION FOR DYE-SENSITIZED SOLAR CELL, SEMICONDUCTOR ELECTRODE FOR DYE-SENSITIZED SOLAR CELL, AND METHOD FOR PRODUCING DYE-SENSITIZED SOLAR CELL

摘要

Provided are a metal complex dye represented by formula (I), a photoelectric conversion element, and a dye-sensitized solar cell. Formula (I): M(LD)(LA).(Y)mY In the formula, M represents Fe2+, Ru2+ or Os2+. LD represents a tridentate ligand represented by formula (A), and LA represents a specific tridentate ligand that differs from the aforementioned tridentate ligand, wherein three cyclic coordinating groups are linked. In formula (A), Ar1 and Ar2 each independently represent a specific heterocyclic group such as a benzene ring group or a triazole ring. Y represents a counterion for when a charge must be neutralized, and mY represents an integer from 0 to 2.
