Abstract
A radio frequency transparent photovoltaic cell includes a back contact layer formed of an electrically conductive material, at least one aperture formed in the back contact layer, and at least one photovoltaic cell section disposed on the back contact layer. An airship includes one or more radio frequency antennas disposed in an interior of the airship. One or more radio frequency transparent photovoltaic cells are disposed on an outer surface of the airship.
Claims10
A method of fabricating a photovoltaic cell back contact layer at least partially transparent to radio frequency electromagnetic radiation having at least one predetermined frequency, comprising:
- creating an electrically conductive back contact layer;
- creating a first aperture in the back contact layer and configured to pass signals of a first predetermined radio frequency band, the first aperture having a first footprint;
- and
- creating a second aperture formed in the back contact layer and configured to pass signals of a second predetermined radio frequency band, the second aperture having a second footprint, wherein the first footprint is larger than the second footprint, and wherein the first predetermined radio frequency band is different than the second predetermined radio frequency band, and wherein each of the first and second apertures has a cross shape.
