| Abstract | ||
| In this study the luminescent solar concentrators (LSC) plates doped with fluorescein-sodium dye laser have been prepared in the laboratory at room temperature with(0.5mm) thickness .The concentration of the fluorescein-sodium dye laser were( 10-5,10-4) mol/L. Then they compared with pure epoxy panel. The optical characteristics have been studied like (absorption, transmittance, reflectance and energy gap) also the optical constant were calculated including (absorption. coefficient, refraction index and extinction coefficient ) for all panels. The effect of increasing concentration leads to shift the absorbance, absorption coefficient and extinction coefficient towards higher wavelength, their values also increase with increasing the concentrations. With regard to transmission ,reflectance and refractive index the concentration effect also leads to the same displacement, but their values decrease with increasing the concentration. The results also shown that the value of the energy gap is decreased from (3.6eV) for epoxy resin to (2.3,2.25)eV for the both concentrated panels. | ||
