Abstract—In this work we develop the idea of using a Poly Methyl Methacrylate (PMMA) polymer doped with optically active molecules such as photovoltaic encapsulation materials wholes ensuring concentration of photons in the region where there is a high spectral response of solar cells by the Luminescent Down Shift (LDS) system. The results showed that the short-circuit current increased by 9%. These solar energy conversion systems are subject to a set of constraints upon exposure to environmental conditions, these processes have adverse effects on the long-term performance. The resistance of the doped PMMA an increase temperature was tested by Raman spectroscopy in the presence of a temperature rise of controlled system (DSC), the effect of some cycles of increasing in temperature on the optical properties of PMMA (Absorption, transmission and fluorescence) were presented. Moreover, the effect of this treatment in the LDS/c-Si solar cell performance was studied.
