A thin-layer solar module includes a plurality of interconnected solar cells, having in the order indicated the layers (a) a substrate 3; (b) a first electrode layer 4; (c) a semiconductor layer 5; and (d) a second electrode layer 6. At least one non-linear recess is disposed in the first electrode layer and a second non-linear recess is disposed in the second electrode layer and in the semiconductor layer, wherein a first projection of the first non-linear recess onto the substrate 3 and a second projection 10 of the second non-linear recess onto the substrate intersect or contact each other at least two projection points. The thin-layer solar module has at least one island-shaped contact region extending in a direction vertical to the substrate through the layers (a) through (d). A third recess is present in the semiconductor layer 5 within the island-shaped contact region 11 and is filled with an electrically conductive material. |
