Paper Abstract

From the viewpoint of improvement of energy efficiency in buildings, the so-called " smart window" with dynamic control of solar radiant energy throughput is very attractive, especially for the glass manufacturers. Several types of smart windows using chromogenic compounds have so far been proposed. Among them, the electrochromic device is believed to be the most suitable for the smart window owing to its controllability of the solar transmittance as well as the memory effect. One of the key technologies to fabricate the electrochromic smart windows is to form electrochromic films with large area. The electrochromic film represented by tungsten trioxide has been prepared mainly by the physical vapor deposition methods; however, these are generally expensive and are not suitable to make a uniform and thick film over a large area.
