  • Patent number: 9604877
    Abstract: Certain example embodiments relate to an improved method of strengthening glass substrates (e.g., soda lime silica glass substrates). In certain examples, a glass substrate may be chemically strengthened by creating an electric field within the glass. In certain cases, the chemical tempering may be performed by surrounding the substrate by a plasma including certain ions, such as Li+, K+, Mg2+, and/or the like. In some cases, these ions may be forced into the glass substrate due to the half-cycles of the electric field generated by the electrodes that formed the plasma. This may advantageously chemically strengthen a glass substrate on a substantially reduced time scale. In other example embodiments, an electric field may be set in a float bath such that sodium ions are driven from the molten glass ribbon into the tin bath, which may advantageously result in a stronger glass substrate with reduced sodium content.

  • Patent number: 9593527
    Abstract: Certain example embodiments of this invention relate to vacuum insulating glass (VIG) units having improved seals made using two different frit-based edge seal materials, and/or methods of making the same. In certain example embodiments, a first frit material is applied around peripheral edges of first and second glass substrates. The first frit material, which may be bismuth-based in certain example embodiments, is fired with a heat treatment (e.g., thermal tempering) process. A second frit material, which may be VBZ-based in certain example embodiments, is applied and at least partially overlaps with the fired first frit material. The first frit material acts as a primer, and the second frit material helps seal together the VIG unit. The second frit material is fired at a significantly lower temperature that enables the glass to retain the temper or other strength imparted by the heat treatment.

  • Patent number: 9593019
    Abstract: Certain example embodiments relate to methods for large area graphene precipitation onto glass, and associated articles/devices. For example, coated articles including graphene-inclusive films on substrates, and/or methods of making the same, are provided. A metal-inclusive catalyst layer (e.g., of or including Ni and/or the like) is disposed on the substrate. The substrate with the catalyst layer thereon is exposed to a precursor gas and a strain-inducing gas at a temperature of no more than 350-600 degrees C. for 10s or 100s of minutes. Graphene is formed and/or allowed to form both over and contacting the catalyst layer, and between the substrate and the catalyst layer, in making the coated article. The catalyst layer, together with graphene formed thereon, is removed, e.g., through excessive strain introduced into the catalyst layer as associated with the graphene formation. Products including such articles, and/or methods of making the same, also are contemplated.

  • Patent number: 9574352
    Abstract: Improved building-integrated photovoltaic systems according to certain example embodiments may include concentrated photovoltaic skylights or other windows having a cylindrical lens array. The skylight may include an insulated glass unit, which may improve the Solar Heat Gain Coefficient (SHGC). The photovoltaic skylight and lens arrays may be used in combination with strip solar cells. Arrangements that involve lateral displacement tracking systems, or static systems (e.g., that are fixed at one, two, or more predefined positions) are contemplated herein. Such techniques may advantageously help to reduce cost per watt related, in part, to the potentially reduced amount of semiconductor material to be used for such example embodiments. A photovoltaic skylight may permit diffuse daylight to pass through into an interior of a building so as to provide lighting inside the building, while the strip solar cells absorb the direct sunlight and convert it to electricity, providing for SHGC tuning.

  • Patent number: 9556070
    Abstract: An insulating glass (IG) window unit includes first and second substrates, and a low-emissivity (low-E) coating supported by one of the substrates. The low-E coating has two silver based infrared (IR) reflecting layers and allows the IG window unit to realize an increased SHGC to U-value ratio, and an increased thickness ratio of an upper silver based layer of the coating to a bottom silver based layer of the coating. The low-E coating is designed to have a low film-side reflectance, so that for example when the low-E coating is used on surface number three of an IG window unit the IG window unit can realize reduced visible reflectance as viewed from the outside of the building on which the IG window unit is mounted or is to be mounted.

  • Patent number: 9556066
    Abstract: Certain example embodiments of this invention relate to insulating glass (IG) units including three substantially parallel spaced apart glass substrates, wherein at least two of the surfaces include low-emissivity (low-E) coatings and at least some of the non-low E coated surfaces have antireflective (AR) coatings disposed thereon. In certain example embodiments, low-E coatings are provided on the second and fifth surfaces of the IG unit, and each internal surface of the IG unit that does not support a low-E coating does support an AR coating. Additional AR coatings may be provided on one or both of the outermost surfaces in certain example embodiments. In some cases, the center substrate need not be heat treated because of the reduced absorption enabled by providing the low-E coatings on the two outermost substrates, as well as the reduced heat accumulation in the center lite itself and in the two adjacent spacers.

  • Patent number: 9499436
    Abstract: Certain example embodiments relate to a sunlight-scattering thin-film coating disposed on a substrate for greenhouse applications. The surface morphology of the coating promotes a better and more uniform light distribution. For instance, at least one thin-film layer disposed on a substrate may be textured so as to create surface features on the order of 0.1-5 microns, with the surface features being sized to cause (a) light having a wavelength of greater than or equal to about 800 nm incident thereon to primarily scatter to angles less than 30 degrees relative to a major surface of the substrate and (b) light having a wavelength of less than or equal to about 700 nm incident thereon to primarily scatter to angles greater than 20 degrees relative to the major surface of the substrate. This arrangement may advantageously direct beneficial light towards plant life while directing parasitic light away from the plant life.

  • Patent number: 9499433
    Abstract: Certain example embodiments of this invention relate to coated articles including substrates that support printed patterns and thin film layer stacks that can have the patterns and the layer stacks formed thereon and then be cut, heat treated, and optionally built into an insulated glass unit, laminated to another substrate, and/or used in another product. In certain example embodiments, this is made possible by bonding to the glass the frit material used in forming the pattern, re-annealing the glass following the bonding, disposing the thin film layer stack on the re-annealed substrate supporting the bonded pattern, and then cutting and heat treating. The frit advantageously does not re-melt during heat treatment because the melting temperature is higher than the temperature used in heat treatment, and/or as a result of secondary recrystallization of the frit material. Associated methods also are provided.
