  • Patent number: 10472881
    Abstract: A substrate is coated on one face with a thin-films stack having reflection properties in the infrared and/or in solar radiation including a single metallic functional layer, based on silver or on a metal alloy containing silver, and two antireflection coatings. The coatings each include at least one dielectric layer. The functional layer is positioned between the two antireflection coatings. At least one of the antireflection coatings includes an intermediate layer including zinc oxide Zn1O1+x with 0.05<x<0.3 and having a physical thickness of between 0.5 nm and 20 nm, or between 2.5 nm and 10 nm.
    Type: Grant

  • Patent number: 10421687

The coatings each include at least one dielectric layer. The functional layer is positioned between the two antireflection coatings. The stack also includes a terminal layer which is the layer of the stack which is furthest from the face. The terminal layer is a metallic layer consisting of zinc and tin, made of SnxZny with a ratio of 0.1?x/y?2.4 and having a physical thickness of between 0.5 nm and 5.0 nm excluding these values, or even between 0.6 nm and 2.7 nm excluding these values.

  • Patent number: 8470434
    Abstract: The invention relates to a transparent glass substrate, associated with a transparent electro-conductive layer capable of constituting an electrode of a photovoltaic cell and composed of a doped oxide, characterized by the interposition, between the glass substrate and the transparent electroconductive layer, of a mixed layer of one or more first nitride(s) or oxynitride(s), or oxide(s) or oxycarbide(s) having good adhesive properties with glass, and one or more second nitride(s) or oxynitride(s) or oxide(s) or oxycarbide(s) capable of constituting, possibly in the doped state, a transparent electroconductive layer; a method for producing this substrate; a photovoltaic cell, a tempered and/or curved glass, a shaped heating glass, a plasma screen and a flat lamp electrode having this substrate.

  • Patent number: 8187714
    Abstract: Transparent substrate, especially made of glass, associated with an electrode, especially one suitable for solar cells, characterized in that the electrode comprises a first transparent electrically conducting layer composed of an undoped mineral oxide, said first layer being coated with a second transparent electrically conducting layer composed of the same mineral oxide, said mineral oxide however being doped.
