PORPHYRIN COMPLEX AND DYE-SENSITIZED SOLAR CELL

摘要

[Problem] To provide a porphyrin complex that has exceptional light collection characteristics, and that when employed as a sensitizing dye in a dye-sensitized solar cell, is able to improve the cell characteristics. [Solution] The present invention relates to a porphyrin complex comprising metal atoms and a porphyrin derivative. The porphyrin derivative has one attracting group and at least two electron-donating groups, which are bonded to the porphyrin ring. The attracting group is an arylethynyl group substituted with a functional group having attraction and electron-withdrawing properties (the aryl ring may have additional substituent groups). The at least two electron-donating groups are bonded to the porphyrin ring, in an asymmetric positional relationship with respect to the arylethynyl group.
