Abstract
The invention relates to a transparent electroactive system that includes two electrodes () juxtaposed on the same side of a closed space () containing electroactive substances. The two electrodes are separated by a distance of less than 250 μm, and a barrier () extending towards the inside of the closed space is placed between the electrodes. The separation between the electrodes is thus not visible, and a mutual neutralization between the electroactive substances is prevented. Advantageously, the electroactive substances are contained in cells () separated from each other within the closed space. The barrier () can thus be distinct from separation walls () between the cells, or can be assimilated with some intercellular walls.
