Two Promising Methodologies for Dealing with Changes in Optical and Electrical Properties of Polymer Electrolytes (SPEs)

Abstract

Variation of light absorption, mainly the shift and shape of the absorption edge, are two promising approaches aimed at understanding the fundamental processes of optical transitions in crystalline and amorphous materials. This allows us to better understand the structure of energy bands. Significant advances have been made in understanding the fundamental chemical and physical properties of polymers to improve the efficiency of photovoltaic and optoelectronic devices. However, the relationship between these two properties has not been determined. Characterization of the optical properties of polymers, such as infrared dichroism, light absorption, Raman polarization, and emission spectra, is an important method for studying electronic properties. To consider conductivity and thermal savings in the range (300–500 K), we also investigate the effect of temperature on conductivity. Activation energies found in different cases were used. Ionic conductivity has been found to be temperature-dependent for all SPE formulations. It has been found that the ionic conductivity of the membrane presents two regimes, the first being at relatively low temperatures. The ionic conductivity exhibits a relatively independent behavior of temperature. It was found that the dielectric constant of the SPE polymer electrolytic system increased with increasing temperature. This behavior is typical of pole insulators because the alignment of the dipoles becomes easier with increasing temperature and thus the dielectric constant increases.
