Thing-to-Thing Optical Wireless Power Transfer Based on Metal Halide Perovskite Transceivers

This paper proposes a novel conceptual system of optical wireless power transfer between objects, whether stationary or in-motion. Different from the currently existing optical wireless power transfer systems, where the optical transmitter and receiver are two distinct devices, the proposed system in this paper employs a single device - an optical transceiver, which is capable of working as both light absorption and emission. This optical transceiver is fabricated from a metal halide perovskite which yields superior features such as low costs, capability of flexibly attached on curved surfaces, thin and light weight. Therefore, the whole system size and cost can be significantly reduced, while perovskite transceivers can be made adaptive to any surface. This will contribute to realize a thing-to-thing optical wireless power transfer system, in which surfaces of objects/things are covered (fully or partially) by perovskite transceivers, enabling them to wirelessly charge or discharge from the others.
