Abstract

Prussian Blue (PB) thin films were prepared by chemical bath deposition onto fluorine doped tin oxide (FTO) coated glass substrates. Elelctrochromic behavior of the films was examined in an electrochromic device (ECD) consisted of home-built glass cell with a 1 mol/dm3 KCl as an electrolyte, PB film as working, and FTO as counter electrodes. These films showed electrochromism changing color from deep blue in as deposited state, to green in oxidized state, and back to blue and transparent (colorless) in reduced state. Visible transmittance spectra of the PB thin films in bleached and colored states were recorded in-situ. Absorption coefficients spectra were calculated using the transmittance spectra. The output integral of the spectral intensity and the integral of the spectral modulation were calculated by taking the solar irradiance spectrum AM 1.5 for a normal illumination on a PB – based ECD, and the absorption coefficients spectra of the PB films in their bleached and colored states
