Electrochromic device design towards large-scale applications
- Asahi Glass Co., Ltd., Yokohama (Japan). Advanced Glass R and D Center
The present state and performance of relatively large area transmissive electrochromic devices were reviewed. The largest size prepared has an electrode distance of about 60 cm. The response speed was shown to be limited mainly by the resistance of the transparent conductive coating, though the sheet resistivity available now is fairly low, around 10 {Omega}/sq. The rate of the process in the transmissive device will change from transparent electrode limited to electrolyte limited if the sheet resistivity could be lowered down to less than 1 {Omega}/sq. The present stat of large area transmissive EC devices is summarized. More investigation is necessary for a more accurate understanding of the physical and chemical properties of WO{sub 3} films, especially to provide countermeasures to degradation so that better device performance can be accomplished.
