Abstract
The present invention relates to a 2,7-carbazole-containing polymer represented by formula 1 and an organic photovoltaic device comprising the conductive polymer as a photoelectric conversion material. The conductive polymer has high photon absorption efficiency and improved hole mobility and is prepared by introducing a specific amount of a carbazole compound either into a polymer, consisting only of a donor functional group containing one or more aromatic monomers, or into a donor-acceptor type polymer comprising a repeating acceptor group introduced into a donor functional group. The conductive polymer can be used as a photoelectric conversion material for organic thin film transistors (OTFTs) or organic light-emitting diodes (OLEDs). Furthermore, the invention provides an organic photovoltaic device comprising the carbazole-containing conductive polymer as an electron donor, and thus can achieve high photoelectric conversion efficiency in organic thin film solar cells.
