ABSTRACT:
An electrochromatic glazing system is provided. The system comprises a first glass sheet covered with a first transparent electrically conductive film and a second glass sheet covered with a second transparent electrically conductive film. A film of electrochromatic material, an electrolyte, and a counterelectrode are interposed between the first and second transparent electrically conductive films. The first and second electrically conductive films are connected to a voltage generator by an electrical control circuit and the voltage generator receives a set-point value from a control unit equipped with a memory and generates a potential difference as a function of the temperature of the electrolyte.
