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 between −1800 and +1600 mV, the transmission spectra for the electrochromic window show good light modulation in the 400–2700 nm wavelength region. For example, at 1000 nm the transmission changes from 0.76 to 0.22.
