摘要:
The present disclosure provides a method and system for processing a glass. The method comprises heating a soldered area of glass with initial heating parameters; determining a change of an optical property of a section of the glass at a soldered section part corresponding to the soldered area; and adjusting at least one of heating parameters based on change in the optical property, such that the change in the optical property at the soldered section part reaches or exceeds a predetermined degree. By determining the relation between the change in the optical property at the soldered section part and the residual stress, heating parameters suitable for reducing and even eliminating the residual stress in the glass could be explored in a cost-effective way in accordance with the change in the optical property detected by the detecting component, thereby effectively eliminating the residual stress in the glass.

Methods for reducing stress on an isopipe during manufacture of a drawn glass sheet are disclosed including a method comprising providing an isopipe having a root, heating the isopipe to a predetermined temperature, maintaining the isopipe at the predetermined temperature for a period of time sufficient to relieve at least a portion of a tensile stress on the isopipe root, coupling the isopipe to a down-comer, and then providing glass to the isopipe. Also disclosed is a method comprising heating an isopipe such that the temperature difference between the weir and the root of the isopipe, after heating and prior to coupling, is less than about 100 °C. A method comprising application of a compressive force to the ends of an isopipe root during heating is also disclosed.

The current disclosure relates to highly homogeneous glass sputter targets with a large aspect ratio and a high relative density. The glass sputter targets have properties that are desirable for forming thin films by physical vapor deposition processes such as sputtering. Methods for producing chalcogenide glass sputter targets are included.

Method for crystal growth from a surfactant of a metal-nonmetal (MN) compound, including the procedures of providing a seed crystal, introducing atoms of a first metal to contact with the seed crystal thus forming a thin liquid metal wetting layer on a surface of the seed crystal, setting a temperature of the seed crystal below a minimal temperature required for dissolving MN molecules in the wetting layer and above a melting point of the first metal, each one of the MN molecules being formed from an atom of a second metal and an atom of a first nonmetal, introducing the MN molecules which form an MN surfactant monolayer, thereby facilitating a formation of the wetting layer between the MN surfactant monolayer and the surface of the seed crystal, and regulating a thickness of the wetting layer, thereby growing an epitaxial layer of the MN compound on the seed crystal.
摘要:
A method for manufacturing a glass concentrator for a solar module. The method includes providing a glass material in a molten state and processing the glass material in the molten state to form a ribbon glass including a first surface and a second surface. Additionally, the method includes subjecting the first surface to one or more drum members to form a plurality of concentrating structures while continuously passing the ribbon glass via the second surface over a plurality of rollers. Each of the concentrating structures includes an aperture region, an exit region, and one or more reflection regions. The aperture region is configured to receive incoming light and the one or more reflection regions are configured to concentrate the received incoming light to the exit region. The method further includes cutting the ribbon glass into one or more sheets of glasses including a predetermined number of the plurality of concentrating structures.
