A device comprising a thin film solar cell with an integrated flexible antenna, such as a meander line antenna, is disclosed. In an embodiment, the device comprises a substrate and an array of solar cells disposed on the substrate, wherein the array of solar cells are interconnected by metal conductors that carry DC power from the solar cells and which form at least part of the flexible antenna. In their capacity as an antenna, the metal conductors operate cooperatively with the solar cells to radiate an RF signal, receive an RF signal, or both radiate and receive an RF signal. The device optionally comprises a choke disposed on the substrate and electrically coupled to the array of solar cells, wherein the choke operates to impede conduction of the RF signal. A method of making the disclosed device is also disclosed.
