CONDUCTING POLYMER TO WHICH PYRENE COMPOUNDS ARE INTRODUCED, AND ORGANIC SOLAR CELL USING SAME

摘要

The present invention relates to a conducting polymer to which pyrene compounds shown in chemical formula 1 below are introduced, and an organic solar cell using the conducting polymer as a photoelectric conversion material. The present invention provides the conducting polymer with improved hole mobility, by introducing a particular amount of pyrene compounds to a polymer which is configured with only a donor functional group in which one or more of various aromatic monomers are included, or to a donor-acceptor type polymer in which a repeated acceptor is introduced to a donor functional group. Thus, the invention may be used as a material for organic optoelectronic devices such as organic photo detectors (OPDs), organic light emitting diodes (OLEDs), organic thin film transistors (OTFTs), and organic solar cells. Further, since the invention provides the organic solar cell that uses, as an electron donor, the conducting polymer to which the pyrene compounds are introduced, high power conversion efficiency (PCE) is obtained.
