Abstract: The present invention relates to a pyrene-containing conductive polymer represented by formula 1 and an organic solar cell comprising the same as an organic photovoltaic material. The conductive polymer has improved hole mobility as a result of introducing a specific amount of pyrene either into a polymer, which consists only of a donor functional group comprising one or more aromatic monomers, or into a donor-acceptor type polymer comprising a repeating acceptor introduced into a donor functional group. Thus, the conductive polymer can be used as an organic photovoltaic material in organic photodiodes (OPDs), organic light-emitting diodes (OLEDs), organic thin-film transistors (OTFTs), organic solar cells and the like. In addition, an organic solar cell showing high power conversion efficiency (PCE) can be provided using an organic photovoltaic material comprising the pyrene-containing conductive polymer as an electron donor.

Abstract: A method for preparing a polysilicon rod using a metallic core means, including: installing a core means in an inner space of a deposition reactor used for preparing a silicon rod, the core means being constituted by forming at least one separation layer on the surface of a metallic core element and being connected to an electrode means, heating the core means by supplying electricity through the electrode means, and supplying a reaction gas into the inner space for silicon deposition, thereby forming a deposition output in an outward direction on the surface of the core means. The deposition output and the core means can be separated easily from the silicon rod output obtained by the process of silicon deposition, and the contamination of the deposition output caused by impurities of the metallic core element can be minimized, thereby a high-purity silicon can be prepared more economically and conveniently.
