Flexible solid-state electrochromic devices based on amorphous WO3 thin films

Abstract

The amorphous WO3 thin films have been uniformly synthesized on the conducting flexible substrates by thermal evaporation deposition, and their solid-state electrochromic (EC) devices have also been fabricated by using a solid electrolyte in the devices. The color change in the solid-state EC devices has been investigated by a UV-Vis spectrophotometer, and the results have demonstrated the potential application of the electrochromic effect of the amorphous WO3 thin films in the flexible solid-state EC devices.
