PHOTOELECTRIC CONVERSION ELEMENT THAT CONTAINS DYE CONSISTING OF BINUCLEAR RUTHENIUM COMPLEX HAVING SUBSTITUTED BIPYRIDYL GROUPS, AND PHOTOCHEMICAL CELL

摘要

The present invention relates to a binuclear ruthenium complex dye having a higher absorption coefficient and capable of absorbing light of longer wavelength for realizing a photoelectric conversion element and a photochemical cell which may convert solar light into electricity over a wide wavelength range and exhibit high photoelectric conversion efficiency; and a binuclear ruthenium complex dye for realizing a photoelectric conversion element and a photochemical cell which may have high durability.
