To use the solar cell for simultaneous energy harvesting and communication, two branches, shown in, are connected as a load across the two ends shown in ]. In the communication branch, a capacitor, , connected in series to a load, , is used to block the DC signal.
Recent advances in solar cell-based optical wireless communication (OWC) have led to promising market prospects for solar cells in fifth-generation (5G) communication networks and beyond for signal detection [ ].
In 2020, Fakidis et al. at the University of Edinburgh and Fraunhofer Institute for Solar Energy Systems further investigated the trade-off between energy harvesting and wireless communication for a 2-m wireless GaAs VCSEL and PV-based optical link [ ].
With advancements in materials and PV technology, most VLC, FSO, and UWOC systems based on various novel solar cells have shown encouraging performance in terms of data rates and transmission distances. This provides a solid foundation for the establishment of future SAGO communication networks.
