Polyvinyl alcohol (PVA) – Polyethylene glycol (PEG) based solid polymer blend electrolytes have been prepared by the solution cast technique. The absorption spectra has been recorded in the wavelength range (280-800) nm. The absorption coefficient, refractive index and extinction coefficient have been determined. The results show that the optical constants increase with the increasing of weight percentages. Also, the electrical properties have been calculated such as electrical conductivity(σ)by using LCR meter which is used to measure the inductance (L), capacitance (C), and resistance (R) of a component, the results show that the electrical conductivity decrease with increasing of the percentages weight of polymers (PVA-PEG).
