Abstract

An organic photosensitive optoelectronic device includes an anode, a cathode, and a donor-acceptor heterojunction between the anode and the cathode, the heterojunction including a donor-like material and an acceptor-like material, wherein at least one of the donor-like material and the acceptor-like material includes a subphthalocyanine, a subporphyrin, and/or a subporphyrazine compound, wherein the subporphyrin or subporphyrazine compound includes boron.
