ELECTRON-DONATING ORGANIC MATERIAL FOR PHOTOVOLTAIC DEVICES, MATERIAL FOR PHOTOVOLTAIC DEVICES, AND PHOTOVOLTAIC DEVICES

摘要

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 R¹ to R¹⁰ 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; R¹¹ and R¹² 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.)
