Tungsten trioxide can be prepared into a WO3 electrochromic film, which acts as an EC layer in a five-layer film structure, for applying to assemble an all-solid-state electrochromic device. And these electrochromic devices are mainly used for research or practical applications of energy-saving windows. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html So, what are the five-layer film structures of the electrochromic device? ——TC/EC/IC/CE/TC, wherein TC is a transparent conducting layer – a transparent electrode, EC is an electrochromic layer, lC is an…
