Methods are disclosed for planarisation of a coated glass substrate by deposition of a silazane based layer thereon. Coated substrates according to the invention exhibit improved properties in terms of reduced roughness, lower haze and higher visible light transmission and the coated surface may be exposed to the external environment, for example as surface 1 or surface 4 of a double glazing unit. The resulting smooth surface is less susceptible to marking and scratch damage, and offers enhanced surface energy (improved hydrophobicity).

Various embodiments herein relate to electrochromic devices, methods of fabricating electrochromic devices, and apparatus for fabricating electrochromic devices. In a number of cases, the electrochromic device may be fabricated to include a particular counter electrode material. The counter electrode material may include a base anodically coloring material. The counter electrode material may further include one or more halogens. The counter electrode material may also include one or more additives.

The present invention relates to a method capable of easily manufacturing a curved thin glass sheet and a curved joined glass sheet to which functionality is added.

The invention provides an IG unit comprising two panes and a between-pane space located between the two panes. A desired surface of a selected one of the two panes bears a coating comprising both a transparent conductive oxide film, and an overcoat film located over the transparent conductive oxide film. The IG unit further comprises a bus bar and a transparent conductor bridge each located over the desired surface. The bus bar is spaced apart from the coating and is connected electrically to the transparent conductive oxide film by virtue of the transparent conductor bridge extending from the bus bar to a top surface of the overcoat film. In some embodiments, the IG unit further comprises a frit located over the desired surface and extending around a perimeter thereof. The bus bar is located over the frit. Certain embodiments provide a refrigerator having a door comprising such an IG unit.

Thin-film devices, for example electrochromic devices for windows, and methods of manufacturing are described. Particular focus is given to methods of patterning optical devices. Various edge deletion and isolation scribes are performed, for example, to ensure the optical device has appropriate isolation from any edge defects. Methods described herein apply to any thin-film device having one or more material layers sandwiched between two thin film electrical conductor layers. The described methods create novel optical device configurations.

A method of making a coated article includes forming a first coating over a first surface of a substrate; and forming a second coating over a second surface of the substrate. The second coating includes a first conductive layer including tin oxide and at least one material selected from the group consisting of tungsten, molybdenum, and niobium.

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.
