Abstract
The objective of the present invention is to provide a photovoltaic device which has high photoelectric conversion efficiency and an electron-donating organic material which comprises a conjugate polymer having a structure of a thieno[3,4-b']thiophene skeleton with an alkoxycarbonyl group in which a specific alkyl group part is a straight chain alkyl group or an alkanoyl group in which the alkyl group part is a straight chain alkyl group and a benzo[1,2-b:4, 5-b′]dithiophene skeleton with a heteroaryl group.
