Thermal damage in luminescent solar concentrators (LSC) for photovoltaic systems

Abstract

The temperature dependence of the optical efficiency of luminescent solar concentrators (LSC) has been studied. It has been found that in the range room temperature (RT) − 100 °C an important thermal degradation is produced. The damage depends not only on the temperature but also on the nature of the dye and can reach values as high as 37% in the case of RhB. The damage is partially recovered when the LSC is cooled to RT.
