Abstract
Energy savings in buildings can be achieved by using electrochromic windows which change colour by the application of an external voltage. We have studied an electrochromic window by combining polyaniline (PANI), prussian blue (PB) and tungsten oxide (WO 3) with poly(2-acrylamido-2-methylpropane-sulphonic acid) (PAMPS) as a solid organic polymer electrolyte binding the three electrochromic materials together. Transmission spectra in the 290–3300 nm wavelength region for the window at different applied potentials were recorded and show good light modulation. For instance, by applying a voltage between − 1800 and + 1600 mV, the transmission changes from 0.76 to 0.11 at 100 nm. The window is able to regulate 49% of the total solar energy.
