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

Abstract

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. Our developed OPVC has a high power conversion efficiency (PCE) of 9.8%. The VLP system can be operated at a low illumination of 130 lux. The regression machine learning (ML) algorithm is used to enhance the positioning accuracy.

Robot Localization and Navigation Using Visible Light Positioning and SLAM Fusion

“…Generally, PD is used as the receiver to capture the signal for the VLC system. There are many works use the PD and solar cells [19]- [21] as the receiver of VLP. PD is not an ideal VLP device, since it is sensitive to the light intensity variation and the diffuse reflection of the light signal, which degrades the positioning accuracy [22].…”

Evaluation of an AGC for a Solar Panel as a Receiver in a VLC System Applied to Access Control

“…Entre ellos, los paneles solares son propuestas atractivas debido al bajo costo, fácil acoplamiento con sistemas electrónicos y la generación de energía de manera simultánea [11]- [13]. Tales características son indispensables en aplicaciones como sistemas de control de acceso, localización en interiores o internet de las cosas [14], [15]. Por lo anterior, el trabajo propuesto en [16], presenta una técnica basada en modulación por amplitud de pulso para mejorar el desempeño del panel solar como receptor óptico.…”
