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.

Claims

1. An electrochemical device comprising:

at least one carrier substrate; and

a stack of functional layers comprising at least one electrically conducting layer comprising 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, said higher-conductivity material having a surface resistance which is lower than a surface resistance of said electrically conducting layer,

wherein the stack of functional layers is arranged between two substrates, each of which may be rigid, of glass type or rigid polymer or semi-rigid or flexible of PET type.

2. The device of claim 1, wherein said polymer is a polycarbonate or PMMA.

3. The device of claim 1, wherein the layers are transparent or absorbent.
