Abstract:
Luminous cascade systems is a new system applied in the design of photovoltaic module with low cost and high
efficiency, They consist of a transparent plate of polymethyl methacrylate (PMMA) doped with luminescent dyes, the
sides of this last are attached with mirrors to concentrate the light to the solar cell which mounted on the rear face of
the plate.The solar spectrum cross the PMMA wafer is absorbed by the luminescent molecules optically active and
remitted in high wavelength more suitable for the spectral response of solar cell. A pn-si solar cell is studied.
Approximately, an increasing in conversion efficiency of 9% is achieved.
