Abstract
The invention relates to transparent electrochromic systems which each include one pair of supply electrodes and at least one pair of polarization electrodes. The polarization electrodes prevent a reaction of mutual neutralization of the electroactive substances of the systems from causing unnecessary consumption of electric current. Said electrodes also prevent a neutralization reaction from limiting a lower value of light transmission of the systems. For this purpose, the polarization electrodes produce an electric field inside the systems, which attracts the electroactive substances that have already reacted with the supply electrodes to different areas.
