| abstract |
The invention relates to a plate (82) consisting of a transparent material. Said plate has a texture on the surface thereof, provided with a plurality of patterns which are in relief, indented or projecting (83, 84, 85). Said pattern has a first side (80) and second side (81) which are non-parallel to each other, the lines at the base of the sides being parallel however. The first side forms an angle with the general plane of the plate, said angle being larger than the angle formed by the second side with the general plane of the plate, the angles in question being those on the inside the material if the pattern projects from the surface, or those on the outside the material if the pattern is indented on the surface. The inventive plate improves luminous transmission towards a photovoltaic cell, especially when arranged in a vertical position, for example on the surface of an acoustic wall. |
