Self-Powered IoT Node Utilizing a Perovskite Photovoltaic for Green OWC Systems

This work explores the feasibility of incorporating Perovskite Photovoltaic (PPV) cells into Internet-of- Things (IoT) devices. The aim is to enable these devices to both receive data and harvest energy simultaneously, thus creating a dual self-powered IoT node. We have characterised a PPV that can be used for data reception and energy harvesting simultaneously. We have analysed the data reception capabilities of the PPV of 1mm² of the active area. In this work, we propose an equivalent electric circuit for the PPV used as a receiver, and determine its frequency response. The results show a bandwidth of,...,120 Hz a 1mm² PPV. The energy harvesting module is based on the active area of 4,000 mm² of the same PPV, which improves the autonomy of the IoT node by 42 and 81 % for indoor and outdoor environments, respectively.
