Abstract
The fabrication and design of electrochromic windows based on cathodically coloring amorphous tungsten trioxide (a-W03) and anodically coloring iridium oxide (a-Ir02) are described. Using electrochemical data obtained from slow-sweep-rate cyclic voltammetry and coloration efficiency measurements of the individual a-W03 and Ir02 films, the optical switching characteristics of an a-W03/a-Ir02 electrochromic window may be predicted. The evolution of the optical absorbance spectra of a-W03/a-Ir02 windows are presented and used to determine the solar (350-1300 nm) and visible (400-700 nm) transmittance. The effect of multicycle switching and temperature (-20 to 60°C) on the performance of the electrochromic windows are also discussed.
