Abstract
The invention relates to a transparent electrochromic system (100) which includes two pairs of transparent supply electrodes (1-4), which are intended for being electrically connected to variable power sources (20, 21). The electrodes of the two pairs are supported by separate outer walls (10, 11) of the system, on either side of a closed volume which contains electroactive substances. The electrochromic system has superior dynamics and switching rate. Various embodiments of the invention correspond to various modes for connecting the electrodes to the power sources, and to various partitions of the closed volume into separate cells (13).
