Novel Li-Fi transceiver design based on perovskite photodiode devices (PeLiFi)

Perovskite is an emerging low-cost and high-quality material, that show significant potential to revolutionize photovoltaic and lighting sectors in Organic and Large Area Electronics (OLAE) devices. Their simple and inexpensive processing methods, such as solution-based synthesis and printing, make them attractive for flexible and lightweight electronic devices. In this work, perovskite suitability has been tested for telecommunication applications, particularly Li-Fi links. The perovskite devices were integrated into a telecom system, including an FPGA handling signal processing, LED array, analog transmitter circuitry, and driving electronics for the perovskite photodiode. 4-PPM modulation format has been adopted due to resilience in low SNR. The purpose is to thoroughly characterize the setup to assess the suitability of perovskite devices for Li-Fi scenarios or combined PV and Li-Fi usage. This research aims to advance the application of perovskites in telecommunication and expand their potential in various electronic devices.
