Abstract

Based on our previous studies on the rf reactive sputtered nickel oxide films with nanostructure and its electrochromism which was supposed that electrochromic effect of the films is attributed to the reversible change of the non-stoichiometry in the nanocrystalline grain boundaries and interfaces due to the injection and ejection of Li⁺ ions, a prototype of all-solid-state NiO/WO₃ complementary electrochromic device using Li_xTaO_y thin film as inorganic electrolyte was designed and prepared. The results indicate that the solar reflectance of the device could be modulated from 0.15 in colored state to 0.60 in bleached state with excellent cyclic reversibility, durability and high response speed (less than 0.3 sec from colored state to bleached state).
