A transparent plate includes at least two parallel main borders and has, in relief on at least one of its main surfaces, repetitive pyramidal relief features, each including an apex, a base, and a set of edges that join the apex to the base, and at least one edge of the features being such that its projection in the general plane of the plate is substantially parallel to the two parallel main borders. The plate may be combined with photovoltaic cells so as to enhance the transmission of light to the cells. The plate can easily be produced by hot rolling. |
