PIGMENT AND DYE-SENSITIZED SOLAR CELL

摘要

PROBLEM TO BE SOLVED: To provide a pigment excellent in conversion efficiency, and to provide a dye-sensitized solar cell.

SOLUTION: The pigment is excellent in conversion efficiency and expressed by one of four chemical constitutional formulae of (H-102, H-105, HRD-1 and HRD-2), and the dye-sensitized solar cell is constituted by using the pigment as a photosensitizer. A mol optical absorption coefficient is high in a wavelength range of not shorter than 400 nmm, and the conversion efficiency as the solar cell is high.
