NEUTRAL MIXED LIGAND TRANSITION METAL COMPLEXES AS ACTIVE MATERIALS IN SOLID-STATE ORGANIC PHOTOVOLTAIC DEVICES

摘要

The present invention describes novel “black absorbers” comprising mixed ligand metal-organic complexes to be used in OPVs. The invention describes three representative metal-organic dyes that exhibit strong absorptions spanning the entire UV/Vis portion of the solar light and, in the some cases, well within the NIR. The invention further describes the fabrication of an OPV device by co-doping P1 in a standard polymer/fullerene matrix commonly used in a bulk heterojunction device structure.
