Title Photoelectric conversion material containing fullerene derivative
Abstract (US9039935)
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.
Scope of claims [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]
3. The photoelectric conversion material according to claim 1, wherein X1 represents a phosphonate group.
[claim4]
4. The photoelectric conversion material according to claim 1, wherein the support is a conductive substance.
[claim5]
5. The photoelectric conversion material according to claim 4, wherein the conductive substance is a metal, a metal oxide, or carbon.
[claim6]
6. The photoelectric conversion material according to claim 5, wherein the metal is selected from the group consisting of platinum, gold, silver, copper, aluminum, rhodium and indium.
[claim7]
7. The photoelectric conversion material according to claim 5, wherein the metal oxide is selected from the group consisting of an indium-tin composite oxide and a tin oxide doped with fluorine.
[claim8]
8. A photoelectric conversion device having a self-assembled monomolecular film of the photoelectric conversion material according to claim 1.
[claim9]
9. A photoelectric conversion device having an ITO electrode on which the self-assembled monomolecular film of the photoelectric conversion material according to claim 1 is formed.
[claim10]
10. A solar cell having the photoelectric conversion device according to claim 9.
