WO3 film is the most popular material for assembly of an inorganic all solid-state electrochromic device with the characteristics of low power consumption (<2 V), high coloration ef?ciency and memory effects. So, such an electrochromic device has many potential applications in smart windows, mirrors, displays, and optical switching devices. Wherein, WO3 smart windows is regarded as an energy-saving window with a wide application in buildings and high-class automobiles.

According to the experts, in the inorganic all solid-state electrochromic device, a change in color (light transmittance) takes place in the presence of an applied voltage. And an electrochromic device generally consists of a transparent electrically conducting layer, electrochromic cathodic and anodic coloring materials, and an ion conducting electrolyte. wherein, WO3 is a cathodic coloring material. Such devices are currently prepared using proton-conducting solid polymer electrolytes for practical use, because of the advantages of this process, which involves seal development during manufacture and the inhibition of bubble formation.
