Experts say that as a common coating method, magnetron sputtering has many advantages. For example, electrochromic thin films can be prepared with good stoichiometric ratio by adjusting the oxygen-argon ratio, power, sputtering time and substrate temperature during magnetron sputtering. Moreover, the film is fast to be formed. The obtained film has uniform particle size and good compactness. Also, the bonding property is good between the film and the FTO conductive glass. In a word, spray method has a very efficient production rate and requires only a heat treatment device and a spray device, so it is inexpensive, and more importantly, it can be used to produce large-area electrochromic devices.
