Transmission through an Electrochromic Window based on Polyaniline, Tungsten Oxide and a Solid Polymer Electrolyte

Abstract

An electrochromic window was fabricated by combining polyaniline and tungsten oxide with a solid polymer electrolyte binding the two electrochromic materials together. Polyaniline and tungsten oxide were deposited electrochemically on indium-tin-oxide glass plates. By applying a voltage of ± 2V, the transmission spectra for the electrochromic window show good light modulation in the 400–900 nm wavelength region, e.g. from 16% to 86% at 800 nm.
