Exploring Bandwidth Capabilities of Solar Cells for VLC Applications

The growing number of connected wireless devices is causing interference in traditional radio frequency bands, which restricts communications capacity and efficiency. This issue motivates the pursuit of alternative technologies, such as optical wireless communication, which could potentially resolve electromagnetic congestion. This technology leverages the visible and infrared spectrum, along with other wavelengths, to transmit data. Recently, photovoltaic (PV) modules have emerged as an innovative solution for data reception and enhancing self-sufficiency. However, within a range of industrial settings, including factories, warehouses, and offices, data transmission may be affected by fluctuations in lighting conditions. This work focuses on exploring the impact of lighting conditions on the frequency response of visible light communication (VLC) systems that utilize silicon PV cells as photodetectors, a crucial aspect to optimize the efficiency of data transmission. This analysis opens new possibilities for the effective deployment of PV cells as optical receivers in indoor settings, thereby significantly enhancing the usage of VLC technology in industrial applications.
