Abstract

Silicon photocell acts as the detector and energy convertor in the VLC system. The system model was set up and simulated in Matlab/Simulink environment. A 10 Hz square wave was modulated on LED and restored in voltage mode at the receiver. An energy gathering and signal detecting system was demonstrated at the baud rate of 19200, and the DC signal is about 2.77 V and AC signal is around 410 mV.

Highlights

Solar cell has drawn great interest over the past 30 years, and there is a tendency to use it more widely and practically
Energy gathering can be hardly seen in the visible light communication (VLC)
Research works in this area can be found in [2]; the researchers from Korea used a solar cell as a simultaneous receiver of solar power and visible light communication (VLC) signals

Summary

Introduction

Solar cell has drawn great interest over the past 30 years, and there is a tendency to use it more widely and practically. Energy gathering and signal detecting system is a new idea. We noticed that the silicon-based solar panels could receive VLC data and gather energy at the same time. Research works in this area can be found in [2]; the researchers from Korea used a solar cell as a simultaneous receiver of solar power and visible light communication (VLC) signals. Simulation results indicate that it is possible to gather energy and receive data through the same solar panels. Our experiments based on the prototype show that the solar panels can gather energy for low power circuit and detect the VLC signal at the same time
