Abstract:
Systems and methods for texturing substrates (e.g., glass, metal, and the like) and the textured substrates produced using such systems and methods are disclosed. An exemplary textured substrate includes a surface having a portion with a root-mean-square roughness between 40 to 1000 microns and an autocorrelation function greater than 0.5 for distances less than 50 microns. An exemplary system for texturing a substrate includes a plunger with a textured surface, where a portion of the textured surface has a root-mean-square roughness between 40 to 1000 microns and an autocorrelation function greater than 0.5 for distances less than 50 microns. An exemplary method for texturing a substrate includes the steps of generating a pattern defining a texture, and 3-D printing the pattern on the substrate to form the texture.

Various aspects of systems and methods are provided herein wherein a method, is provided including the steps of: depositing a hot, flexible ribbon material along a plurality of sequentially conveyed molds; rolling a pinch roller over the surface of the ribbon, such that at least one pinch region is actuated in the ribbon as the ribbon is pinched between a pinch edge of the pinch roller and the surface of the mold; and rolling a pin roller over the surface of the ribbon, cooling the ribbon to thereby separate the ribbon along the pinch region into discrete parts.
Abstract:
A method of manufacturing large lens arrays from glass includes heating glass to take a form of a glass sheet of viscous liquid glass floating on liquid metal. Large lens arrays are made by the method and devices and systems are used for making the large lens arrays. The glass sheet has a lower surface in contact with the liquid metal and an upper surface on an opposite side of the glass sheet away from the liquid metal. The method applies a gas flow on the upper surface of the glass sheet to cause the upper surface of the glass sheet to form a pattern of convex lenses in response to local variations in a pressure profile of the gas flow; and cooling the glass sheet to solidify into a rigid, patterned glass sheet.
Abstract:
A glass substrate for an organic EL element, which can improve the light-extraction efficiency of the organic EL element, can be produced with a high productivity. The glass substrate serves as a light-extraction side transparent substrate of an organic EL element. The refractive index λd of the glass substrate is 1.60 or more, and Na2O+K2O are contained at 10 mol % to 20 mol % as glass components. A light-extraction side surface has a relief structure obtained by die molding.
Abstract:
Provided herein is a method for producing glass-ceramic sheets. The method includes texturing at least one surface of a first glass sheet, and stacking the first glass sheet and a second glass sheet. The first glass sheet and the second glass sheet are stacked so that the textured surface of the first glass sheet contacts a surface of the second glass sheet. The first and second glass sheets are cerammed. After cooling, the cerammed first and second glass sheets are separated. Also provided is a pre-form for producing glass-ceramic sheets. The pre-form includes a first glass sheet having a textured surface, and a second glass sheet contacting the first glass sheet. The textured surface of the first glass sheet is in contact with a surface of the second glass sheet.
Abstract:
A method for printing a precision structure on the surface of a glass strip advancing continuously at a rate of at least 1 m/min, using an etching roller (27) applying a printing force against the surface to be etched, the structure to be produced including protruding and recessed regions which have radii of curvature, a preliminary thermal conditioning (26 and 32) being performed upstream of the etching roller; the thermal conditioning is designed to ensure a temperature of the strip (J) over the print thickness and a cooling (29) downstream of the etching roller (27) to ensure a controlled fixing of the structure; the method according to the invention making it possible to determine the parameters that are intimately linked for obtaining a particular structure, notably the print temperature, the printing force and the cooling rate, taking into account a degree of creep between the molding radius (R1) and the post-creep radius (R2).
Abstract:
Invention relates to lenticular sheets made of thermally or chemically hardened mineral glass used for decorative panels, to create three-dimensional visual effects combined with an encoded image. One of the advantages of invention is the fact that it is a proposed mineral lenticular sheet, which underwent chemical or mechanical hardening of its outer parts 18. This increases the mechanical strength and impact resistance. This aspect makes it safer for use under the influence of external factors and in contact with a person. This allows for applying the invention in large scopes in comparison with plastic lenticular screens. Pre-stressing is achieved by thermal or chemical hardening.
Abstract:
A method of manufacturing a transparent pane, in particular a glass pane, which includes on at least one of its main surfaces a surface structure including an assembly of specified individual motifs in relief, in particular pyramids, cones, or truncated cones, created by embossing or by rolling. A structure is created on the surface of the pane constituted by individual motifs, based on one or more basic motifs but which are distinguished from each other by their depth, their height, and/or the perimeter of their base area, and/or by the position of their peak with respect to their base. With this variation, formation of intensity peaks of the reflected light is prevented and at the same time a high quality of light trapping is obtained by panes suitable, for example, for solar applications.
Abstract:
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.
Abstract:
A high transmission and low iron glass is provided for use in a solar cell. The glass substrate may be patterned on at least one surface thereof. Antimony (Sb) is used in the glass to improve stability of the solar performance of the glass upon exposure to ultraviolet (UV) radiation and/or sunlight. The combination of low iron content, antimony, and/or the patterning of the glass substrate results in a substrate with high visible transmission and excellent light refracting characteristics.
