<P>PROBLEM TO BE SOLVED: To provide a photovoltaic element having high photoelectric conversion efficiency. <P>SOLUTION: A material for the photovoltaic element includes a conjugated polymer having the structure shown by general formula (1) (wherein R<SP>1</SP>to R<SP>16</SP>can be the same or different from one another and each of R<SP>1</SP>to R<SP>16</SP>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, R<SP>16</SP>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). <P>COPYRIGHT: (C)2011,JPO&INPIT |
