HYBRID PLANAR-MIXED HETEROJUNCTION FOR ORGANIC PHOTOVOLTAICS

摘要

Two electrodes in a superimposed relationship herein; A mixture that is located between two electrodes, contains at least one donor material having HOMO energy and at least one acceptor material having LUMO energy, and forms a donor-acceptor heterojunction in which at least one donor material and at least one acceptor material are mixed Photoactive layer; A photoactive layer adjacent to and interfacing with the mixed photoactive layer and comprising a material having a HOMO energy within 0.3 eV of the LUMO energy of the at least one acceptor material or within 0.3 eV of the HOMO energy of the at least one donor material; An organic photosensitive optoelectronic device is disclosed comprising a buffer layer adjacent to and interfacing with a mixed photoactive layer.
