摘要

A porphyrin-linked fullerene derivative, which included COOH groups in its fullerene unit, Por-C₆₀(COOH) was synthesized in order to investigate the possibility of promoting the photosensitization of TiO₂. Por-C₆₀(COOH) molecules produced higher photocurrent per molecule than tetrakis(4-carboxyphenyl)-porphyrin molecules. A dye-sensitized solar cell using Por-C₆₀(COOH), in which a C₆₀ unit was introduced between the porphyrin unit and TiO₂, yielded an improvement in energy conversion for light collection.
