<p>The invention is directed to a beam trap (10), particularly for improving the efficiency of a solar cell (12), comprising: a substrate (14) at least partially transmissive for the beams (16) and comprising a beam ingress surface (18) and a beam emission surface (20), and - a plurality of beam reflectors (22) arranged in the substrate (14), wherein each of the plurality of reflectors (22) comprises, in the direction from the beam ingress surface (18) to the beam emission surface (20), a cross section that first broadens and then narrows. Furthermore, the invention is directed to a method for making a beam trap (10), particularly a beam in accordance with the invention, wherein the method comprises the following steps: providing a stamper (24) with a plurality of stamping structures (26), wherein each of the plurality of stamping structures (26) comprises, in the direction of the stamper's normal vector (28), a cross section that first broadens and than narrows; providing a flexible substrate (14) at least partially transmissive for the beams (16); and using the stamper (24) to provide a relief structure (30) in the substrate (14).</p> |
