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.

Transparent glass pane provided with a surface structure

The subject of the invention is a transparent substrate, especially made of glass, which is provided with an electrode, especially for a solar cell, comprising a conductive layer based on molybdenum Mo with a thickness of at most 500 nm, especially at most 400 nm or at most 300 nm or at most 200 nm.

Transparent substrate equipped with an electrode

The subject of the invention is a transparent substrate () having at least one antireflection coating, made from a film (A) comprising multiple thin layers of alternately high and low refractive indexes. The multilayer film comprises, in succession, a high-index first layer (), having a refractive index nof between 1.8 and 2.3 and a geometrical thickness eof between 5 and 50 nm, a low-index second layer (), having a refractive index nof between 1.30 and 1.70 and a geometrical thickness eof between 5 and 50 nm, a high-index third layer (), having a refractive index nof between 1.8 and 2.3 and a geometrical thickness eof at least 100 nm, and a low-index fourth layer (), having a refractive index nof between 1.30 and 1.70 and a geometrical thickness eof at least 80 nm. This antireflection coating can be used in solar modules.

Transparent substrate comprising an antireflection coating

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.

Textured plate comprising asymmetrical patterns

A photovoltaic solar cell including an upper electrode, a layer with light scattering and/or reflection properties, and a lower electrode. The layer with light scattering and/or reflection properties is located between the upper electrode and the lower electrode.

Photovoltaic solar cell and solar module

The invention relates to a glass substrate () provided with an electrode comprising at least one metal oxide-based transparent conducting layer (), characterized in that said layer has an RMS roughness of at least 3 nm, especially of at least 5 nm and/or a mean feature size for this roughness of at least 50 nm.

Transparent substrate comprising an electrode

The subject of the invention is a transparent substrate (6) having at least one antireflection coating, made from a film (A) comprising multiple thin layers of alternately high and low refractive indexes. The multilayer film comprises, in succession: This antireflection coating can be used in solar modules.

A textured transparent panel placed near an element capable of collecting or emitting light. The panel is textured on at least one of its faces by a plurality of geometrical features in relief, such as pyramids or cones. The panel, which may be made of glass, provides excellent light transmission for all light orientations. The panel may be combined with a photoelectric cell, especially one made of polycrystalline silicon, and may also act as a light diffuser, especially for liquid-crystal screens or plasma lamps.

Textured transparent plate with high light transmission

A solar module containing thin-film solar cells positioned between two plates separated by a border seal at the external edge of the plates. The border seal includes an elastomeric spacer that contains a moisture-absorbing medium and is coated with an external peripheral adhesive bead.
