  • Patent number: 10502878
    Abstract: Disclosed herein are systems, methods, and apparatus for forming low emissivity panels. In some embodiments, a partially fabricated panel may be provided that includes a substrate, a reflective layer formed over the substrate, and a barrier layer formed over the reflective layer such that the reflective layer is formed between the substrate and the barrier layer. The barrier layer may include a partially oxidized alloy of three or more metals. A first interface layer may be formed over the barrier layer. A top dielectric layer may be formed over the first interface layer. The top dielectric layer may be formed using reactive sputtering in an oxygen containing environment. The first interface layer may prevent further oxidation of the partially oxidized alloy of the three or more metals when forming the top dielectric layer. A second interface layer may be formed over the top dielectric layer.

  • Patent number: 10479053
    Abstract: A coated article includes a low emissivity (low-E) coating having at least one infrared (IR) reflecting layer of a material such as silver, gold, or the like, and at least one high refractive index layer of or including titanium oxide and at least one additional metal. A doped titanium oxide layer(s) is designed and deposited in a manner so as to be amorphous or substantially amorphous (as opposed to crystalline) in the low-E coating, so as to better withstand optional heat treatment (HT) such as thermal tempering and reduce haze. The high index layer may be a transparent dielectric high index layer in preferred embodiments, which may be provided for antireflection purposes and/or color adjustment purposes, in addition to having thermal stability.

  • Patent number: 10480058
    Abstract: A coated article includes a low emissivity (low-E) coating supported by a glass substrate. The low-E coating includes at least one silver (Ag) based infrared (IR) reflecting layer(s) that is provided adjacent to and contacting at least one protective metallic or substantially metallic doped silver layer in order to improve chemical durability characteristics of the low-E coating. The silver based IR reflecting layer and adjacent protective doped silver layer are part of a low emissivity (low-E) coating, and may be sandwiched between at least transparent dielectric layers. A barrier layer including Ni and/or Cr may be provided over and directly contacting the protective doped silver layer in order to further improve durability of the low-E coating.

  • Publication number: 20190323287
    Abstract: A coated article includes a low-emissivity (low-E) coating. The low-E coating includes at least one infrared (IR) reflecting layer of a material such as silver, gold, or the like, and a dielectric overcoat designed to increase solar heat gain coefficient (SHGC) of the coated article. A dielectric undercoat may also be designed to increase SHGC of the coated article in certain example embodiments. In certain example embodiments, the overcoat and/or undercoat are designed to increase SHGC while also providing for desirably high visible transmission (TY or Tvis) and desirably low normal emittance (En).
