発明の名称 (英語) Photoelectric conversion material containing fullerene derivative
発明の概要(英語) The present invention provides a photoelectric conversion material comprising a fullerene derivative represented by the formula C60(R1)5(R2), wherein each R1 independently represents an organic group having a substituent; and R2 represents a hydrogen atom or a substituted or unsubstituted C1-C30 hydrocarbon group.
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.
特許請求の範囲(英語) [claim1]
1. A photoelectric conversion material of a self-assembled monomolecular film comprising a support and a compound having the following formula (10):
wherein:
R2 represents a hydrogen atom or a substituted or unsubstituted C1-C30 hydrocarbon group; and each R3 is independently a group represented by the following formula (A):
wherein:
X1 represents a phosphate group or a phosphonate group; each R20 independently represents an organic group; and n is an integer from 0 to 4.
[claim2]
2. The photoelectric conversion material according to claim 1, wherein X1 represents a phosphate group.
[claim3]
