WO3 nano film is an EC layer material of an electrochromic device. It is reported that the structure of the electrochromic device has three types including three-layer type, four-layer type and five-layer type. The five-layer type electrochromic device has a structure in which five layers of electrochromic material are sandwiched between two layers of conductive glass. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html The five-layer electrochromic device is constructed using “glass/TC/EC/IC/IS/TC/glass”. Wherein the TC layer, that is, the transparent conductive layer, is…
