Abstract:
A coated article includes a heat treatable (e.g., temperable) antireflection (AR) coating having four layers. The AR coating includes a layer adjacent the glass substrate having an index of refraction substantially matching that of the glass substrate, and having a compressive residual stress. In certain example embodiments, the coating may include the following layers from the glass substrate outwardly: stress-reducing layer/medium index layer/high index layer/low index layer. In certain example embodiments, depending on the chemical and optical properties of the high index layer and the substrate, the stress-reducing layer of the AR coating is selected to cause a net compressive residual stress and thus improve the overall performance of the antireflection coating when the coated article is heat treated.
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.
Abstract:
This invention relates to a transparent conductive coating that is substantially transparent to visible light and is designed to have a visible reflectance which more closely matches that the visible reflectance of the underlying substrate. In certain example embodiments, the transparent conductive multilayer coating includes a silver layer(s) and may be used as an electrode(s) in a capacitive touch panel so as to provide for an electrode(s) transparent to visible light but without much visibility due to the substantial matching visible reflection design.
Abstract:
Embodiments relate to mirrors having a reflective layer of or including silicon aluminum (e.g., SiAl). The mirrors may be first surface mirrors, or second surface mirrors. The SiAl layer may be provided between dielectric layers. The mirrors may be flat or bent in different instances, and may or may not be heat treated. In certain example instances, such mirrors may be used in interior residential, commercial, appliance, and/or other applications.

Abstract:
Certain example embodiments relate to capacitive touch panels. First and second glass substrates are substantially parallel and spaced apart from one another. At least one multi-layer transparent conductive coating (TCC) is patterned into electrodes and located between the first and second substrates. The TCC(s) include(s) at least one conductive layer including silver, a dielectric layer including zinc oxide under and directly contacting the conductive layer including silver, and a dielectric layer(s) including tin oxide or silicon nitride over the conductive layer including silver. Processing circuitry electrically connects to the electrodes and measures an aspect of the electrodes' capacitance. A laminate material is located between the first and second glass substrates. The TCC(s), when blanket deposited, may have a visible transmission of at least 88%, a sheet resistances of no more than 10 ohms per square, and a haze of no more than 0.5%. Mutual and self-capacitance designs are disclosed.
Abstract:
Certain example embodiments of this invention relate to patterned glass that can be used as a cylindrical lens array in a concentrated photovoltaic application, and/or methods of making the same. In certain example embodiments, the lens arrays may be used in combination with strip solar cells and/or single-axis tracking systems. That is, in certain example embodiments, lenses in the lens array may be arranged so as to concentrate incident light onto respective strip solar cells, and the entire assembly may be connected to a single-axis tracking system that is programmed to follow the East-West movement of the sun. A low-iron glass may be used in connection with certain example embodiments. 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.

Abstract:
Certain example embodiments of this invention relate to sputtered aluminum second surface mirrors with permanent protective coatings optionally provided thereto, and/or methods of making the same. A mirror coating supported by a substrate may include, for example, first and second dielectric layers sandwiching a metallic or substantially metallic layer including aluminum, and an optional layer including Ni and/or Cr in direct contact with the metallic or substantially metallic layer comprising aluminum. A protective film may be disposed directly over and contacting an outermost layer of the mirror coating, with the protective film having a peel strength of 200-500 cN/20 mm wide strip.
