Forrest, Stephen R.; Li, Ning

A method of making a bulk heterojunction organic photovoltaic cell by glancing angle deposition. As the disclosed method relies on a trajectory of incident vapor flux that is not parallel to the substrate normal, micro and nano-scale columnar structures of thin films can be grown on the substrate. There is also disclosed a method of forming a donor-acceptor heterojunction by depositing at least one additional organic material over the columnar structures.
