Visible light positioning (VLP) system using low-cost organic photovoltaic cell (OPVC) for low illumination environments

Optics Express, 2020
We propose and demonstrate a received-signal-strength (RSS) based visible light positioning (VLP) system using a low-cost organic photovoltaic cell (OPVC) receiver (Rx). The OPVC is a passive device without the need of external power supply. It could detect VLC signal and harvest energy.
