In the last decades, researchers increased their interest in a new type of wireless communication called Light Fidelity (LiFi). This is because radio bands used in Wi-Fi are becoming saturated and soon will reach their limits. Light Emitting Diodes (LEDs) are used in LiFi as visible light transmitters, and the reception is typically implemented by a prototype/intrinsic-semiconductor/n-type PIN or Avalanche Photodiode (APD) photoreceptor. However, it has a problem with performance reduction under sunlight. Photovoltaic (PV) modules could be potential candidates for outdoor applications but are limited with a bandwidth of hundreds of kHz. In this work, we propose a method based on designing a negative impedance converter (NIC) to broaden the bandwidth of a PV module.
