A coated glass article includes a glass substrate and an anti-reflective coating formed over a first major surface of the glass substrate. The anti-reflective coating includes a color suppression interlayer and a first coating layer deposited over the color suppression interlayer. The first coating layer includes tin oxide and a dopant. The dopant includes antimony, molybdenum, or iron. A second coating layer is deposited over the first coating layer. The second coating layer includes an oxide of silicon. The coated glass article exhibits a total visible light transmittance of 70% or more and a film side visible light reflectance of less than 6.0%.

Coated glass article

A method of manufacture of a coated glazing includes the following steps in sequence a) providing a transparent glass substrate, b) etching a surface of the substrate with an acidic gas, and c) directly or indirectly coating said surface with at least one layer based on a transparent conductive coating (TCC) and/or at least one layer based on a material with a refractive index of at least 1.75.

Method of manufacture of a coated glazing

A light emitting diode display is described including inner and outer panes of glass. The inner pane of glass has first and second major surfaces wherein a visible light reflection from the second major surface is 7.6% or less. The outer pane of glass is in a parallel relationship with the inner pane of glass. One or more light emitting diodes (LEDs) and at least one (a first) interlayer is provided between the inner and outer panes of glass. The first interlayer encapsulates the one or more LEDs. A conductive coating may be formed over the first major surface of the inner pane of glass and at least one (a first) of the one or more LEDs may be provided on the conductive coating, the first light emitting diode being in electrical communication with the conductive coating. The conductive coating may be transparent to visible light.

Insulated glazing units comprising first and second sheets of glazing material with a low pressure space there between are described. The major surface of the second sheet of glazing material not facing the low pressure space has a low emissivity coating comprising at least one layer of fluorine doped tin oxide thereon. There is a first anti-iridescence coating between the low emissivity coating and the second sheet of glazing material. Also described are insulated glazing units comprising three (first, second and third) sheets of glazing material with a low pressure space between first and second sheets of glazing material, and a second space between the first and third sheets of glazing material. There is a low emissivity coating on one or both major surfaces facing the low pressure space. The third sheet of glazing material has a low emissivity coating on both opposed major surfaces thereof.

Sputtered zinc oxide layer is used to improve and control the crystalline properties of a molybdenum back contact used in photovoltaic cells. Optimum thicknesses for the zinc oxide layer are identified.

Growth layer for photovoltaic applications

Transparent conducting electrodes incorporate an interface layer located on the transparent conducting oxide (TCO) layer of the electrode. The interface layer offers a suitable surface for deposition of further layers in order to fabricate electronic devices such as electrochromic devices or organic light emitting diodes. Problems such as pinholes and short circuiting, associated with the inherent roughness of the TCO layer, are reduced.

Interface layer for electronic devices

A coated glass pane comprising at least the following layers in sequence: a glass substrate; a lower anti-reflection layer; a silver-based functional layer; a barrier layer, comprising at least the following three partial barrier layers in sequence from the silver-based functional layer, a lower partial barrier layer based on an oxide of Zn, Ti, ZnSn, InSn, Zr, Al, Sn and/or Si, and/or an (oxi)nitride of Si and/or of Al, having a thickness of at most 5 nm, a central partial barrier layer based on an oxide of Zn, Ti, Zn Sn, InSn, Zr, Al, Sn and/or Si, and/or an (oxi)nitride of Si and/or of Al, having a thickness of at most 5 nm, and an upper partial barrier layer based on an oxide of Zn, Ti, Zn Sn, InSn, Zr, Al, Sn and/or Si, and/or an (oxi)nitride of Si and/or of Al, having a thickness of at most 10 nm; and an upper anti-reflection layer; wherein the central partial barrier layer has a different composition to both the lower partial barrier layer and the upper partial barrier layer.

A process for the production of an optoelectronic device, such as a photovoltaic cell or a light emitting diode is disclosed. The process comprises providing a substrate having a conductive coating on at least one surface, the conductive coating having an initial roughness and at least one or more spikes, and applying a functional component to the coated surface of the substrate. The surface of the substrate having the conductive coating has been subjected to a polishing step using at least one brush to reduce the height of the spikes inherent to the conductive coating and to give the conductive coating a final roughness. By reducing the spikes there is less potential for the optoelectronic device to suffer from electrical shunts which reduce the efficiency of the device.
