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 (17)

1. An electrochemical device comprising:

at least one electronically conducting layer comprising at least one metal oxide including zinc oxide doped with aluminum or fluorine; and

a multicomponent electrode comprising at least one electrochemically active layer and a plurality of conducting strips between the at least one electronically conducting layer and the at least one electrochemically active layer.

2. An electrochemical device comprising:

at least one electronically conducting layer comprising at least one metal oxide including zinc oxide doped with aluminum or fluorine; and

a multicomponent electrode comprising at least one network comprising a plurality of silver-based conducting strips obtained using a low melting point fit in an organic binder.

3. The electrochemical device recited in claim 2 wherein the conducting strips are 0.1 to 0.5 mm wide.

4. The electrochemical device recited in claim 2 wherein the conducting strips are essentially parallel.

5. The electrochemical device recited in claim 2 wherein the conducting strips are 1 to 5 mm apart.

6. The electrochemical device recited in claim 2 wherein the conducting strips are formed on the at least one electronically conducting layer by screen printing.

7. The electrochemical device recited in claim 2 wherein the conducting strips are formed on a substrate by screen printing, and then the at least one electronically conducting layer is formed on the conducting strips.

8. The electrochemical device recited in claim 2 wherein the conducting strips are conducting wires.

9. The electrochemical device recited in claim 1 wherein the metallic strips include stainless steel, silver, gold, silvered copper, or aluminum.

10. The electrochemical device recited in claim 1 wherein the metallic strips are 1 to 5 mm apart.

11. The electrochemical device recited in claim 1 wherein the metallic strips are essentially parallel.

12. The electrochemical device recited in claim 1 wherein the metallic strips form a mesh.

13. The electrochemical device recited in claim 1 wherein the metallic strips are conducting wires.
