Abstract:
A method comprises providing a glass substrate having a surface; spraying the surface with a slurry comprising abrasive particles and water to form an abraded surface; and etching the abraded surface to form a textured glass substrate. The textured glass substrate can be used in photovoltaic cells. A photovoltaic device comprising a light scattering article comprises a glass substrate having a textured surface, wherein the surface comprises smooth craters having an average width of from 1 to 15 microns; a conductive material adjacent to the surface; and an active photovoltaic medium adjacent to the conductive material.
Abstract:
A method is disclosed for producing sheet glass having two faces, at least one of which has a high surface quality, the method comprising a treatment step wherein a stream of glass is contacted with a forming tool, and wherein a reversible adhesion force exists between the stream of glass and the forming tool after contacting. An apparatus is also disclosed for producing sheet glass according to the disclosed and various other methods of sheet glass manufacture, the apparatus comprising a forming tool having a means for controlling the temperature of at least a portion of the surface thereof.
Abstract:
A glass forming system (200) and a method are described herein for forming a glass sheet (230). In one example, the glass forming system and method can use a glass composition with a liquidus viscosity less than 1000 poises to continuously form a glass sheet.
Abstract:
A microfluidic device (100) made from glass, ceramic or vitroceramic, comprises an upper layer (122), a lower layer (124) and an intermediate layer (114), the intermediate layer (114) comprising an upper face (114b) and a lower face (114a), the lower face (114a) comprising a first open structured surface defining a first microfluidic channel (126) and the upper face (114b) comprising a second open structured surface defining a second microfluidic channel (112); the lower surface of the intermediate layer (114) cooperating with a first planar layer closing the first microchannel (126); the upper face (114b) of the intermediate layer (114) cooperating with a second planar layer (130), closing the second microfluidic channel (112) in a sealed manner, and the second planar layer constituting an intermediate layer (130) which cooperates, on its face opposite the intermediate layer (114), with another layer (122) comprising on its inner face (122a) a structured surface defining a third microfluidic channel (128).
Abstract:
Apparatus for downwardly drawing sheet glass include edge directors at opposed ends of a forming wedge. Each edge director includes a first pair of surfaces and a second pair of surfaces extending from a first pair of surfaces. The second pair of surfaces converge toward a portion of the draw plane downstream from a root of the forming wedge. Each edge director can further include a downstream structure extending along the second pair of surfaces and downstream from the root. Methods are also provided for reducing an angle associated with each pair of lateral edges of molten glass ribbons.
