Abstract:
1. A substrate bearing, on a face thereof, 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 electrically insulating fill material that forms a layer separate from said substrate; an electroconductive coating covering the electroconductive network and the electrically insulating fill material in between the strands, in electrical connection with the strands, and in contact with the strands, having a thickness greater than or equal to 40 nm, of resistivity ρ1 less than 10 the composite electrode having a sheet resistance less than or equal to 10Ω/□, wherein the electrically insulating fill material in between the strands includes a high-index material that has a refractive index greater than or equal to 1.65 at 550 nm.
