These films prepared with different concentrations ratio of multiwall carbon nanotubes added to P3HT (0.00025, 0.00050 and 0.00075 g). The values of absorbance, absorption coefficient and refractive index values for pure and doped polymer are increasing with increasing of the concentrations ratio of MWCNTs. The results showed decreasing values of transmittance with all concentrations ratio of MWCNTs, the values of reflectance are increases with increasing of concentration ratio, also results showed decrease of energy gap for allowed direct transition with increasing of doping ratio.
