Title Photoelectric conversion material containing fullerene derivative
Abstract (US8304643)
The present invention provides a photoelectric conversion material comprising a fullerene derivative represented by the formula C60(R1)5(MLn), wherein: each R1 independently represents an organic group having a substituent; M represents a metal atom; L is a ligand of M; and n is the number of Ls.
Further, the present invention also provides a photoelectric conversion device having a self-assembled monomolecular film of the photoelectric conversion material, and a solar cell having the photoelectric conversion device.
