<p>In order to provide a photovoltaic device with high photoelectric conversion efficiency, an electron donating organic material for photovoltaic devices containing a conjugated polymer represented by formula (1) is invented:
(wherein R 1 to R 10 may be the same or different from each other and are each selected from among hydrogen, an alkyl group, an alkoxy group and an aryl group; R 11 and R 12 may be the same or different from each other and are each selected from among hydrogen, an alkyl group, an aryl group, a heteroaryl group and halogen; W, X, Y and Z may be the same or different from each other and are each selected from among a single bond, an arylene group, a heteroarylene group, an ethenylene group, and an ethynylene group; m is 0 or 1; n is within a range of 1 to 1000.)</p> |
