摘要

PROBLEM TO BE SOLVED: To provide a photovoltaic element having high photoelectric conversion efficiency.;SOLUTION: A material for the photovoltaic element includes a conjugated polymer having the structure shown by general formula (1) (wherein R¹ to R¹⁶ can be the same or different from one another and each of R¹ to R¹⁶ is selected from hydrogen, an alkyl group, an alkoxy group, an aryl group, a heteroaryl group and halogen; A is carbon, nitrogen or silicon; when A is nitrogen, R¹⁶ does not exist; W, X, Y and Z can be the same or different from one another and each of W, X, Y and Z is selected from a single bond, an arylene group and heteroarylene groups except a thienothienylene group; n is within the range of 10-1,000).;COPYRIGHT: (C)2011,JPO&INPIT
