20090266407 | TRANSPARENT GLASS PANE PROVIDED WITH A SURFACE STRUCTURE - 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. | 10-29-2009 |
20090320899 | TEXTURED PLATE COMPRISING ASYMMETRICAL PATTERNS - 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. | 12-31-2009 |
20100051093 | GLASS PANE WITH LIGHT-CAPTURING SURFACE STRUCTURE - 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. | 03-04-2010 |
20100116332 | TRANSPARENT SUBSTRATE PROVIDED WITH AN IMPROVED ELECTRODE LAYER - This substrate, having a glass function, is combined with a textured electrode comprising at least one transparent conductive layer based on one or more metal oxides, said layer being covered with at least one functional layer of an element capable of collecting light, and is covered with an interface layer having a textured part comprising a repetition of periodic or aperiodic features in relief. | 05-13-2010 |
20100154862 | METHOD OF OBTAINING A TEXTURED SUBSTRATE FOR A PHOTOVOLTAIC PANEL - The invention relates to a method for obtaining an external covering of a photovoltaic device, said covering being constituted by a glass substrate having texturing in the form of at least one row of grooves that are mutually parallel and preferably spaced by a regular distance d, said method being characterized in that there is used, for the impression of said texturing, texturing means incorporating reliefs whose spacing is different from the distance d between two rows of grooves on the glass substrate. | 06-24-2010 |
20110209761 | GLAZING WITH LIGHT-CONCENTRATING ZONES BY ION EXCHANGE - This flat mineral glass comprises a first free surface and a second free surface, and comprises groups of zones having a high refractive index (n | 09-01-2011 |
20110242664 | SOLAR PANEL ENABLING THE DISPLAY OF AN IMAGE - 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. | 10-06-2011 |
20110281078 | TRANSPARENT GLASS SUBSTRATE AND PROCESS FOR MANUFACTURING SUCH A SUBSTRATE - 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. | 11-17-2011 |
20120183734 | TEXTURED TRANSPARENT PLATE AND METHOD OF MANUFACTURING SUCH A PLATE - A monolithic transparent plate including, on at least one of its faces, at least one region textured by a plurality of geometric features in relief relative to a general plane of the face, each feature having a cross section, parallel to the general plane, which diminishes with distance from the face, from a base to a peak of the feature. The area of the zones of the textured region for which the inclination angle relative to the general plane is less than 30° C. represents less than 35% of the total area of the textured region. | 07-19-2012 |
20120187435 | METHOD FOR MANUFACTURING A STRUCTURE WITH A TEXTURED SURFACE AS A MOUNTING FOR AN ORGANIC LIGHT-EMITTING DIODE DEVICE, AND OLED STRUCTURE WITH A TEXTURED SURFACE - A production method and a structure having a textured surface forming the support for an organic-light-emitting-diode device, which structure is provided on a transparent substrate made of mineral glass on which is optionally deposited an interface film made of mineral glass, the profile of the texture of the surface comprising protrusions and troughs which are defined by an FT or a roughness parameter Rdq such that the protrusions are not too pointed and such that an increase in the extraction efficiency is ensured. The method especially consists in depositing on the glass substrate a coating film and in ensuring a contraction of the assembly by heating and cooling. | 07-26-2012 |
20130020488 | Detector with a Conical Scintillator - A detector of ionizing radiation comprises a photodetector and a scintillator in the shape of truncated cone comprising a large base, a small base and a lateral surface, the large base of the scintillator being coupled to the photodetector, any half-angle at the apex of the cone being in the range between 5° and 35°, the lateral face being coated with a black coating. The detector in accordance with an embodiment can produce a very short pulse. | 01-24-2013 |
