光保真（LiFi），也称为可见光通信（VLC），已经引起了人们的极大兴趣。在这样的通信系统中，光学传感器将接收到的光调制通量转换成被解码的电信号。为了将LiFi视为无线通信的替代解决方案，接收器必须在室内和室外配置中运行。光伏组件可能是解决这一问题的一个办法。在本文中，我们提出的信号噪声比（SNR）响应的频率的两种不同类型的光伏组件。我们详细描述的SNR使用的实验装置，它连接一个基于软件的直流光（DCO）正交频分复用发射器和接收器的硬件光前端。我们分析了不同光照条件下的LiFi性能。我们证明，可用的带宽极大地依赖于环境照明配置。在特定的照明条件下，可以实现大约4 MHz的带宽，对应于大约8 Mbit/s的数据速率。我们提出的照明饱和效应，我们证明，研究中的半透明太阳能电池提高其性能（带宽和数据速率）在高环境照明环境。
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.
