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.
Claims18
An airship, comprising:
- one or more radio frequency antennas disposed in an interior of the airship;
- and
- one or more radio frequency transparent photovoltaic cells disposed on an outer surface of the airship, wherein
- each of the one or more radio frequency transparent photovoltaic cells includes a back contact layer having first and second apertures to provide for passing of radio frequency radiation generated by the one or more radio frequency antennas, wherein
- the first aperture is formed only in the back contact layer and is configured to pass signals of a first radio frequency band, and the second aperture is formed only in the back contact layer and is configured to pass signals of a second radio frequency band, wherein the first radio frequency band is different from the second radio frequency band, and wherein
- the first aperture and the second aperture are of different size.
