Progress on the variable reflectivity electrochromic window

摘要

Recent research progress on an electrically-tunable, variable reflectivity, completely inorganic thin film electrochromic window is discussed. Some of the properties of window cells composed of rf diode sputter-deposited electrochromic layers of cathodically-coloring tungsten oxide and of anodically-coloring lithium cobalt oxide are presented and discussed. It is highly probable that what has been learned regarding the production of such research window cells by rf diode sputtering can be transferred readily to determining the conditions needed to fabricate variable-reflectivity electrochromic windows by one or more production-worthy processes.
