Relationship between sensor size and optical bandwidth in perovskite-based solar cells as VLC receivers

This work focuses on the characterization of perovskite photovoltaic cells (PPVCs) for visible light communication (VLC) in terms of efficiency and bandwidth, especially for indoor and outdoor environments. Moreover, a comparison between different perovskite devices bandgap is carried out to observe the relationship between bandgap-bandwidth and bandgap-efficiency. The results demonstrate the viability of using PPVCs for VLC based on the achieved bandwidth of 4.85 MHz and 22% efficiency.
