Abstract

An electrochemical device includes at least one carrier substrate, and a stack of functional layers including at least one electrically conducting layer that includes metal oxide(s), and a multicomponent electrode including at least one electrochemically active layer, at least one higher-conductivity material and at least one network of one of conducting wires and conducting strips. The higher-conductivity material has a surface resistance that is lower than a surface resistance of the electrically conducting layer. The stack of functional layers is arranged between two substrates, and each may be rigid, of glass type or rigid polymer or semi-rigid or flexible of PET type.
