DONOR-ACCEPTOR TYPE CONDUCTING POLYMER, ORGANIC PHOTOELECTRIC DEVICE USING IT AND ORGANIC SOLAR CELL

摘要

The present invention relates to a conductive polymer in the form of a donor-acceptor (DA), an organic optoelectronic device using the same, and an organic solar cell employing the same. The present invention is a conductive polymer that has a high photon absorption ability, and improves the photo-opening voltage and the morphology of the device by the cross-repetitive introduction of the electron acceptor functional group-containing compound to the electron donor functional group-containing compound consisting of one or more aromatic monomers The organic optoelectronic device having an improved power conversion efficiency (PCE) and a tandem type organic solar cell in which the organic optoelectronic device is arranged in a top and bottom two-layer structure can be implemented.
