Abstract:
1. A radio frequency transparent photovoltaic cell, comprising: a back contact layer formed of an electrically conductive material; at least one first aperture formed in the back contact layer, the at least one first aperture having a first slot and a second slot, and being configured to selectively pass radio frequency electromagnetic radiation having one or more preselected frequencies; and at least one photovoltaic cell section comprising a solar absorber layer disposed on the back contact layer that is at least partially transparent to the radio frequency electromagnetic radiation having one or more preselected frequencies, wherein the first slot and the second slot do not extend through the solar absorber layer wherein the first slot extends in a first direction for a first length, and the second slot extends in a second direction, which is substantially perpendicular to the first direction, for a second length, which is substantially equal to the first length.
