abstract |
The invention concerns a transparent panel (2) comprising at least two parallel main edges (4, 4') and having, in relief, pyramidal patterns, which are repetitive in relief, on at least one of its main surfaces. These pyramidal patterns each have an apex, a base and a set of edges joining the apex to the base, at least one edge (5) of these patterns being of such that its projection in the general plane of the panel is essentially parallel to the two parallel main edges. This panel can be associated with photovoltaic cells (3) in order to increase the light transmission toward the cells. The panel is particularly easy to realized by hot rolling. |
