Luminescent solar concentrator
A luminescent solar concentrator ( English luminescent solar concentrator , LSC) is an optically effective component that can concentrate incident light on a small area, for example a solar cell . They are usually made of plastic .
In contrast to lenses , which are used in conventional concentrating photovoltaics , luminescent solar concentrators can capture not only the direct but also the indirect part of the sunlight. Photovoltaic systems with luminescent solar concentrators could therefore convert more solar energy into electrical energy in regions with a higher proportion of diffuse sunlight (e.g. Europe) . The materials used to date have a modest efficiency of up to 7.1%, although efficiencies of up to 30-40% are theoretically possible.
They were first developed in 1978 by Renata Reisfeld and her research group in Israel.
