All solid-state electrochromic window of Prussian Blue and electrodeposited WO3 film with PMMA gel electrolyte

Abstract

An all solid-state electrochromic window employing Prussian Blue and electrodeposited WO3 film with PMMA gel electrolyte has been fabricated. The electrochromic window shows excellent electrochromism and memory characteristics. The W 4f core level of the WO3 film at different levels of coloration has been investigated using XPS. W 4f peaks become broader after coloration.
