Performance Analysis of a Perovskite-Based Thing-to-Thing Optical Wireless Power Transfer System

This paper presents an analysis on the performance of an optical wireless power transfer system in which optical transceivers made from a perovskite are used. Experiments are performed under different settings, whose resulted data reveal interesting findings. First, system performance is only matched with the existing theory when no collimating lens is employed. Hence, a data-driven mathematical model is proposed and verified when a collimating lens is used. Second, a collimating lens helps increase the amount of wirelessly transferred power and the transfer distance if perfect alignment between optical transceivers is guaranteed, but substantially limits the sliding distance between them otherwise.
