Abstract
In this paper, we studied the effect of micro-size WO3 precipitates on the electrochromic characteristics based on aging test. The electrochromic mechanism can be effectively investigated by a solid-state TaN/WO3/ITO capacitor. The experimental results reveal that WO3 electrochromic devices with optimized aging time of 4 days exhibit a higher optical contrast and longer retention time, which is mainly attributed to the formation of micro-size WO3 precipitates during aging process. The performance improvement using micro-size WO3 precipitates has the potential in future large-area window or energy efficient display applications.
