Title:
ORGANIC PHOTOELECTRIC CONVERSION ELEMENT, METHOD FOR PRODUCING SAME, AND SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2012/153845
Kind Code:
A1
Abstract:
[Problem] The objective of the present invention is to provide: an organic photoelectric conversion element that has a high photoelectric conversion efficiency, superior durability, and favorable coating characteristics; a method for producing the organic photoelectric conversion element; and a solar cell that uses the organic photoelectric conversion element. [Solution] The photoelectric conversion element has, in the given order on a transparent substrate, a transparent first electrode, a photoelectric conversion layer having both a p-type organic semiconductor material and an n-type organic semiconductor material, and a second electrode, and is characterized by the photoelectric conversion layer containing a compound having a substructure represented by general formula (1) as the p-type organic semiconductor material. (In the formula: X each independently represents a fluorine atom or a chlorine atom; R1-R3 each independently represents a hydrogen atom, a halogen atom, an alkyl group, a fluoroalkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, an alkoxy group, a fluoroalkoxy group, an alkylthio group, a fluoroalkylthio group, an alkylamino group, a fluoroalkylamino group, an aryl group, or a heteroaryl group, or alternatively a linking group wherein said groups are bonded together; the aryl group or the heteroaryl group may be a condensed ring structure; and n each independently represents an integer from 0 to 2.)
