Tungsten Oxide Applied for Large Area Electrochromic Device

Large area electrochromic device, with high thermal insulation and high heat preservation performance, is one of the main means to improve the energy-saving efficiency of buildings, wherein tungsten oxide is assembled in the form of an electrochromic film, playing the role of an electrochromic layer. While at present, large-area electrochromic devices have not been promoted. But why?

This is mainly because there are still some problems to be solved in the large-scale production of large-area electrochromic devices. For example, the packaging of large-area electrochromic devices is an urgent problem that needs to be paid attention to and be dealt with in actual production. Experts say that the packaging method plays a decisive role in the smooth scale production of large-area electrochromic devices. In this regard, some experts used a thermocompression film method to assemble an electrochromic film with an electrolyte to test the overall electrochromic performance of the device.
