The chemical bath deposition method was employed for the preparation of iron hexacyanoferrate (FeHCF), cobalt hexacyanoferrate (CoHCF), and tungsten oxide (WO3) films. The films were deposited onto fluorine-doped tin oxide (FTO) coated glass substrates. For practical electrochromic investigations, an electrochromic test device (ECTD) was constructed consisting of FeHCF (or CoHCF) films as the working electrode, together with WO3 film as the counter electrode, in 1 M KCl aqueous solution as an electrolyte. Visible transmittance spectra were recorded in-situ. The output integral of the spectral intensity and the spectral modulation, as well as saved energy, were calculated by taking the solar irradiance spectrum AM 1.5 for a normal illumination on the ECTD and its transmittance data in the bleached and colored states.
