Multilayer element for electrochemical and/or electrically controllable device used in e.g. train, has contact element that penetrates through dielectric adhesive layer, and joins rear electrode and upper transparent surface electrode

摘要

The multilayer element (1) has a lower transparent surface electrode (3) that projects laterally beyond a functional layer (4) and a rear electrode (6), and having a connection element (17) for feeding in voltage. An upper transparent surface electrode (8) projects laterally beyond the rear electrode, and connected to the rear electrode via a transparent dielectric adhesive layer (7). A contact element (22) penetrates through the transparent dielectric adhesive layer, and indirectly connects the rear electrode and upper transparent surface electrode.
