The aim of this project is to develop state-of-the-art technologies in terms of materials sciences and electronic engineering to pursue self-sustaining modern IoT devices. This project seeks to explore and investigate the performance of the emerging photovoltaic (PV), perovskite solar cells (PSCs) for indoor and outdoor applications in IoT devices. The overarching purpose of this project is to pioneer IoT ecosystem towards cost-effective, self-sustainable and efficient technologies based on latest promising perovskite PVs, which weave together the expertise from physicists, chemists and electronic engineers to build advanced prototypes of PV powered-wireless sensors for future IoT industry. The proposed project highly requires interdisciplinary research efforts to deliver the goals, which fulfils the nature of the call of Collaborative Research Program (CRP).
