NOVELTY - An integrated photovoltaic (PV) cell and radio-frequency (RF) antenna assembly, comprises a PV cell; and at least two horizontal portions of conductive material, each of the at least two horizontal portions of conductive material being secured under the PV cell. Two of the at least two horizontal portions are used for providing an electrical potential difference and the RF antenna is provided using the PV cell and at least one of the at least two horizontal portions of conductive material.    USE - The integrated PV cell and RF antenna assembly is used in integrated PV cell and aperture-coupled patch antenna, integrated PV cell and monopole antenna, IFA, and PIFA (all claimed). The integrated PV cell and RF antenna assembly is used for converting photon energy into direct current electrical energy and for radiating and/or receiving electromagnetic waves.    ADVANTAGE - The integrated PV cell and RF antenna assemblies may be easily integrated with other electronic devices, such as an RF transceiver and/or power management devices and with any material; enable a cost reduction by integrating at least one PV cell with RF antenna capabilities into a single element instead of having two discrete elements; enable a reduction of the number of elements used in a system; are flexible, conformable to any object or body shape and placed over any material, constituting smart materials, such as smart textile; has a thickness which may be very small, i.e. in the nanometer or the micrometer range; provide a lightweight system; may be used for a fixed, mobile, portable, or wearable system; enable a maximization of solar or light radiation absorption with three-dimensional, rotating PV cell element, and/or foldable configurations; provide a direct integration of RF differentially-excited integrated PV cell and RF antenna assemblies, such as dipoles or loops, with an electronic RF transceiver device; and enable a direct integration with other thin film technologies, such as thin film transistors used for display, digital, analog/RF circuits, thin film batteries, or a direct integration of organic and/or nanoscale electronic technologies, leading to a low cost mass production roll-to-roll or reel-to-reel (R2R) manufacturing.
