ORGANIC PHOTOELECTRIC CONVERSION ELEMENT AND SOLAR CELL

摘要

[Problem] The purpose of the present invention is to provide: an organic photoelectric conversion element having high photoelectric conversion efficiency and excellent durability; and a solar cell equipped with the organic photoelectric conversion element. [Solution] An organic photoelectric conversion element which comprises a transparent first electrode, a photoelectric conversion layer comprising a p-type organic semiconductor material and an n-type organic semiconductor material and a second electrode which are arranged in this order on a transparent substrate, and which is characterized in that the photoelectric conversion layer contains a compound having a partial structure represented by general formula (1) or (1') as the p-type organic semiconductor material. (In the formulae, X1's independently represent -S-, -O- or -NR2-; Y1's independently represent -CR3= or -N=; R1-R3 independently represent a hydrogen atom, an alkyl group which may have a substituent, a fluorinated alkyl group which may have a substituent, or a cycloalkyl group which may have a substituent; L1's independently represent a single bond or a substituent selected from an arylene group, a heteroarylene group, a carbonyl group, -COO- and -CONR'- (wherein R' represents a hydrogen atom or an alkyl group); A represents a bivalent acceptor unit; D1 and D2 independently represent a donor unit; and m and n independently represent an integer of 0-2.)
