摘要

Research in light-fidelity (LiFi), also called visible light communication (VLC), has gained huge interest. In such a communication system, an optical sensor translates the received luminous modulation flux into an electrical signal which is decoded. To consider LiFi as an alternative solution for wireless communication, the receiver must be operational in indoor and outdoor configurations. Photovoltaic modules could appear as a solution to this issue. In this paper, we present signal-to-noise ratio (SNR) response in the frequency of two different kinds of photovoltaic modules. We characterize in detail the SNR by using an experimental setup which connects a software-based direct current optical (DCO)-orthogonal frequency division multiiplexing emitter and receiver to hardware optical front ends. We analyze LiFi performances under different lighting conditions. We prove that the available bandwidth depends drastically on ambient lighting configurations. Under specific lighting conditions, a bandwidth around 4 MHz corresponding a data rate around 8 Mbit/s could be achieved. We present the lighting saturation effects and we prove that the semi-transparent solar cell under study improves their performances (both bandwidth and data rate) in high ambient lighting environments.
