Abstract
The invention relates to an electrochemical device () having electrically controllable optical and/or energy transmission properties comprising a substrate (), a functional system () formed on the substrate and a cover film () formed on the functional system. The functional system comprises a bottom electrode coating (), formed on the substrate, a top electrode coating () and at least one electrochemically active film () located between the two electrode coatings, the electro-chemically active film being able to switch reversibly between a first state and a second state having optical and/or energy transmission properties different from the first state. The cover film defines at least one surface cavity () that passes through the cover film without penetrating the top electrode coating and the device comprises electrical connection means () arranged at least partially in at least one surface cavity for electrical contact with the top electrode coating.
