Solar spectral conversion for improving the efficiency of luminescent solar concentrators and other applications

Short abstract:

A luminescent solar concentrator (LSC) consists of a piece of glass or plastic plate coated with luminescent centers that absorb sunlight and emit it at a longer wavelength. A substantial part of the longer-wavelength light is trapped by total internal reflection and guided to the edges of the LSC plate, where it is absorbed by small area photovoltaic cells. LSCs provide an exciting new approach to harvest solar energy in buildings and mobile electronics. By converting windows and displays into LSC waveguides, it is possible to transform these passive surfaces into energy harvesting devices.


Spectral conversion or spectral modification is the process of altering the spectral distribution of light. Luminescent solar concentrators provide a way for shifting the spectral distribution of the sunlight in order to have more photons with the required energy to match the band gap of the solar cell. More recently, spectral modification has also shown promise as an effective method of improving alga growth and other applications, such as optogenetics. We will discuss some novel applications of spectral conversion techniques.
