Abstract

Electrochromic systems with their reversible optical switching ability offer important and interesting application possibilities. Work was carried out in our laboratory towards the fabrication of an all-solid electrochromic system. Lithiation studies of two transition metal oxides (W0₃ and V₂0₅) were done for their use as base electrochromic layer and counter electrode layer in the solid system. Also a thermally evaporated layer of LiBO₂ was studied for its application as ion conducting layer. The optimum results from these studies were used for the fabrication of an all-solid electrochromic prototype. The results on the electrochromic performance of this system are presented. Several hundred coloration and bleaching cycles of such systems have been carried out without any change in its performance. All results indicate the high suitability of such a system for "smart" window application.
