"Nano-scale light intensity concentration control" was invented by Stephen J. Fonash (State College, Pa.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A photovoltaic or light detecting device is provided that includes a periodic array of dome or dome-like protrusions at the light impingement surface and three forms of reflector/back electrode at the device back.
