| Abstract | ||||
| Visible light communication (VLC) has grown rapidly in recent years as an approach to meeting the ever-increasing need for data. Solar cells with dual-energy harvesting and data collection functionalities are becoming the preferred choice for photodetectors on the receiver side of the VLC system as global awareness of energy-related issues grows. This study investigates the design of a low-cost Light Fidelity (Li-Fi) system with a photodetector made of solar panels. The proposed system is capable of data transmission and energy harvesting at the same time. The power produced could be used to energize a user terminal or at least extend its working time. It also goes into how various factors like distance, visibility, and angle impact Li-Fi communication. On a software level, modulation and demodulation have been implemented, and the algorithms for them have been clarified in this research. The prototype was put to the test by transmitting a text message from one PC to another through visible light. | ||||
