Can reflective materials improve bifacial photovoltaic system efficiency?

The study presented here investigates the enhancement of bifacial photovoltaic (PV) system efficiency through the use of various reflective materials, including free-space luminescent solar concentrators (FSLSCs), specular mirrors, and diffuse reflectors.

Can specialized reflectors improve PV system efficiency?

The findings highlight the potential of FSLSCs and specialized reflectors to increase PV system efficiency and offer flexible solutions for improving energy yield throughout the year, particularly during periods of high demand. 1. Introduction

Does reflected light affect bifacial PV panels?

Specifically, we explored a system where south-facing bifacial PV panels are illuminated by reflected light from a façade behind them. Our findings indicate that specular, mirror-like reflectors significantly boost yield but cause uneven illumination on the rear of the panels.

Why do solar project developers not use reflectors?

Reflectors are not widely used by solar project developers now, in part because solar panels prices have come down so much. It has been typically cheaper and simpler to add more panels to an installation, rather than boost the output of panels by reflecting more light on them.

Do reflectors increase solar system output?

By showing how the reflectors scatter light as a function of wavelength, we have started to take the risk out of using reflectors with solar panels, as well as show how the reflectors greatly increase solar system output. Most importantly, we tested the model outside in a real array.

Can bifacial PV systems improve solar power performance?

We are confident that a variety of bifacial PV systems incorporating diffuse reflectors and FSLSCs can be designed to significantly enhance solar power system performance.
