Patent number: 8866008Abstract: 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.Type: GrantFiled: March 15, 2013Date of Patent: October 21, 2014Assignee: Saint-Gobain Glass FranceInventors: Nils-Peter Harder, Ulf Blieske, Dirk Neumann, Marcus Neander, Michele Schiavoni, Patrick Gayout

Patent number: 8174766Abstract: A plate of transparent material including, on its surface, a texture including a plurality of a feature in relief, whether in a form of depressions or projections. The feature includes a first face and a second face that are not mutually parallel, lines at a base of the faces being parallel. The first face forms, with the general plane of the plate, a larger angle than the angle formed by the second face with the general plane of the plate, the angles being angles inside the material if the feature is a projection, or angles on the outside of the material if the feature is a depression. The plate improves light transmission toward a photovoltaic cell, in particular when the plate is in a vertical position, for example on the surface of a noise barrier.Type: GrantFiled: June 13, 2006Date of Patent: May 8, 2012Assignee: Saint-Gobain Glass FranceInventors: Michele Schiavoni, Patrick Gayout, Nils-Peter Harder, Ulf Blieske

Publication number: 20110281078Abstract: This transparent glass substrate has at least one face which is provided with a texturing formed by a plurality of geometric features in relief relative to a general plane of the face, this texturing being adapted in order to ensure a transmission of radiation through the substrate greater than the transmission of radiation through a substrate that is identical but lacks texturing. The face of the substrate is also provided with an antireflection layer having a refractive index between the refractive index of air and the refractive index of the glass. The antireflection layer is an etched out superficial portion of the glass substrate on the side of the face, which comprises a structure based on silica and voids having a characteristic dimension between 0.5 nanometers and 50 nanometers.Type: ApplicationFiled: January 22, 2010Publication date: November 17, 2011Applicant: Saint-Gobain Glass FranceInventors: Michele Schiavoni, Marcus Neander, Pascal Roemgens

Publication number: 20110242664Abstract: An optical assembly configured to display an image on a solar panel covered on at least a part of its surface with a lenticular array, between which an image in the form of substantially equidistant parallel bands with a specific pitch is arranged. The lenticular array has a plane internal surface and an external surface formed by external faces of a series of adjacent identical transparent cylindrical elements whose generatrices are parallel to the bands. The external side of the base of each cylindrical element has an asymmetric profile. The width of each cylindrical element is equal to the pitch of the bands. The bands are arranged so that, for a first angle range of given incidences at which the optical assembly is intended to be observed, radiation can reach a zone in which a band is arranged, and for a second angle range of lower given incidences, radiation can reach an active surface of the solar panel in a zone at least partially not masked by the bands.Type: ApplicationFiled: December 10, 2009Publication date: October 6, 2011Applicant: SAINT-GOBAIN GLASS FRANCEInventors: Guillaume Counil, Michele Schiavoni, Patrick Gayout

Publication number: 20110209761Abstract: This flat mineral glass comprises a first free surface and a second free surface, and comprises groups of zones having a high refractive index (n2) and zones having a low refractive index (n1) which are formed in the thickness of the flat glass between the first and second free surfaces, over a depth of between 1 and 1000 ?m starting from the first free surface. These high-index zones and low-index zones alternate along a direction transverse to the thickness direction of the glass between the first and second free surfaces, the high-index zones flaring out from the first free surface toward the second free surface, and the envelope surfaces of the high-index zones making an angle (?) of at least 65° with respect to the first free surface.Type: ApplicationFiled: November 2, 2009Publication date: September 1, 2011Applicant: SAINT-GOBAIN GLASS FRANCEInventors: Guillaume Counil, Michele Schiavoni, Arnaud Huignard, Julien Sellier, Xavier Brajer

Publication number: 20100051093Abstract: Transparent panes made of glass or of synthetic material, which simultaneously create good light trapping properties by linear structural elements and allow a thermal treatment and hardening of the glass without warping. Groups of parallel elements for which the orientation of the longitudinal extension of the elements alternates from one group to another are formed globally on the surface of the substrate. Moreover, the parallel elements can include a curvature superimposed on their longitudinal extension, which makes it possible to obtain a non-oriented reflected image with a weak screen effect. These panes can be used as covering for photovoltaic components designed to use solar energy, and can also serve a decorative purpose in the construction industry, for example for glazed doors or panes for furniture.Type: ApplicationFiled: June 13, 2006Publication date: March 4, 2010Applicant: SAINT-GOBAIN GLASS FRANCEInventors: Nils-Peter Harder, Ulf Blieske, Dirk Neumann, Marcus Neander, Michele Schiavoni, Patrick Gayout
