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: 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 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.
