Abstract:
1. A transparent electrochromic system, allowing clear vision across said system, and comprising: parallel first and second outer walls, the system being transparent for a viewing direction across the outer walls between two opposite sides; a network of internal walls placed between the outer walls, said internal walls extending perpendicularly to said outer walls and defining a set of cells juxtaposed in parallel to said outer walls; portions of liquid and/or gel contained respectively in the cells; first and second electroactive substances distributed in the portions of liquid and/or gel, with respective electrical redox potentials that are different, at least some of the first and second electroactive substances having a variable optical effect between an oxidized form and a reduced form of said substances; two transparent power supply electrodes carried together by the first outer wall, and configured to be connected respectively to two power supply terminals of a variable electrical power supply unit, each of said power supply electrodes being in direct electrical contact with the portions of liquid and/or gel contained in at least some of the cells for transferring electrons to or from at least some of the electroactive substances, in an inverse way between said first and second electroactive substances at a given time; and a first additional transparent electrode without direct electrical contact with said power supply electrodes inside the electrochromic system, said first additional transparent electrode being parallel to said power supply electrodes inside at least some of the cells.
