Quasi-symmetric electrochromic device for light modulation.

ABSTRACT

A new quasi-symmetric electrochromic device is described for transmission modulation of a switchable window. The calculation technique to design such an electrochromic window for transmission (or reflection) modulation is applied to the (electrode/WO(3)/electrolyte/WO(x)/electrode) system. Advantages and limits of such a quasi-symmetrical system are also discussed.
