Organic double-heterostructure photovoltaic cells having reciprocal-carrier exciton blocking layer

摘要

A photosensitive cell comprising an anode and a cathode, a donor-type organic material and an acceptor-type organic material forming a donor-acceptor junction connected between the anode and the cathode, and an exciton blocking layer connected between the acceptor-type organic material of the donor-acceptor junction and the cathode, wherein a Fermi level of the cathode is no more than 1 eV higher than a HOMO of the exciton blocking layer.
