Patent ID: 8362686

Claim:
A substrate bearing, on one main face, a composite electrode, which comprises: an electroconductive network which is a layer formed from strands made of an electroconductive material based on a metal and/or a metal oxide, and having a light transmission of at least 60% at 550 nm, a space between the strands of the network being filled by an electroconductive fill material; an electroconductive coating covering the electroconductive network, and in electrical connection with the strands, having a thickness greater than or equal to 40 nm, of resistivity ρ 1 less than 10 5 Ω·cm and greater than the resistivity of the network, the coating forming a smoothed outer surface of the electrode; the fill material being electroconductive with a resistivity ρ 2 greater than the resistivity of the network ρ 0 and less than the resistivity ρ 1 , or with a resistivity ρ 2 greater than ρ 1 , having a thickness greater than the thickness of the strands, covering the electroconductive network, the electroconductive coating then covering said fill material, or the fill material being made of said electroconductive coating, the electroconductive coating then substantially filling the space between the strands; the composite electrode having a sheet resistance less than or equal to 10 Ω/□.
