Abstract
An all-solid-state electrochromic device comprises a transparent base material, and an electrochromic multilayer-stack structure formed on the transparent base material. The electrochromic multilayer-stack structure comprises a first transparent-conductive film formed on the transparent base material, an ion-storage layer formed on the first transparent-conductive film, a solid-electrolyte layer formed on the ion-storage layer, and an electrochromic layer formed on the solid-electrolyte layer. The electrochromic layer comprises a reflection-controllable electrochromic layer. In one exemplary embodiment, the electrochromic layer comprises a reflection-controllable layer that comprises at least one of antimony and an antimony-based alloy. A second transparent-conductive film can be formed on the reflection-controllable layer, or between the reflection-controllable layer and the solid-electrolyte layer. In one exemplary embodiment, the second transparent-conductive layer comprises a base metal and/or a base metal alloy.
