Abstract

The fabrication of such an all-solid-state EC device using the combination of amorphous WO₃ film as the electrochromic layer and VO₂ as the counter electrode is studied. Lithiation studies of two transition metal oxides (WO₃ and VO₂) were done for their use as base electrochromic layer and counter electrode layer in the solid device. A dry method of lithiation of the device is proposed and characterized completely for it use in the fabrication of EC device. The properties of thermally evaporated LiAlF₄ were also studied for its use as the ion conducting layer. Using these three materials an all-solid-state electrochromic device has been fabricated and studied for its use as a `smart window.'
