Abstract
A transparent electrochromic system includes a cellular structure, two power supply electrodes together supported on a single wall, and at least one additional electrode. The additional electrode can be used as a reference electrode or as a polarization electrode. The additional electrode can also form a condenser with a fourth electrode that is added to the system, in order to control a migration of certain electroactive substances responsible for coloring and decoloring the system. The operation of the system can thus be improved.
