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.
Claims14
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 the steps of:
- creating an electrically conductive back contact layer having a thickness of at least one skin depth at a lowest predetermined frequency;
- and
- creating one or more apertures only in the back contact layer, each aperture at least partially transparent to radio frequency electromagnetic radiation having a predetermined frequency.
