Tungsten Oxide Nano Film Applied for Electrochromic Device

tungsten oxide nano film applied for electrochromic device picture

Tungsten oxide nano film is one of the most studied and used electrochromic layer materials that can be used to assemble an electrochromic device. According to experts, electrochromic devices can be considered as electrochemical cells. And they are structurally sandwich-type multilayer electrochemical devices. Such a device consists mainly of three parts, the working electrode, the electrolyte and the counter electrode. Wherein each layer appears in the form of a film. The thickness of each layer of film depends on specific requirements.
