A WO{sub 3} based quasi-symmetric smart window
- Univ. de Moncton, New Brunswick (Canada). Dept. of Physics
Smart windows comprised of optically switching electrochromic (EC) materials have opened a very important possibility for an efficient management of energy in automobiles and in buildings. In the present work the authors have studied in detail the lithiation behavior of reactively sputtered crystalline tungsten oxide (WO{sub 3}) films. These films, depending on their thickness and other deposition conditions, exhibit a wide range of changes under lithium insertion from deep coloration to no coloration at all. This gives the possibility of using the WO{sub 3} films either as electrochromic layer or as counter electrode (CE) layer for lithium ion storage, respectively. From these results a quasi-symmetric electrochromic system encompassing a-WO{sub 3} as EC layer and a c-WO{sub 3} as the CE layer is fabricated and studied for its electrochromic behavior.
