Luminescent Solar Concentrators

Luminescent Solar Concentrators (LSCs) have been developed to capture and harness light in places without consistent exposure to the sun, like cities. In appearance and physical properties they are similar to transparent Perspex or window panels. LSCs contain highly luminescent compounds that absorb sunlight and re-emit it at longer wavelengths. The light is trapped and directed to the edges of the device through a process called total internal reflection. A small strip of photovoltaic cell can then be positioned on the outside edges of the LSC to capture this reflected light and generate electricity.
