Abstract

A thin-film solar module with a substrate and a layer structure applied thereon that comprises a rear electrode layer, a front electrode layer, and an absorber layer arranged between the back electrode layer and the front electrode layer. Serially connected solar cells are formed in the layer structure by patterning zones, wherein each patterning zone comprises a first patterning line for subdividing at least the rear electrode layer, a second patterning line for subdividing at least the absorber layer, and at least one third patterning line for subdividing at least the front electrode layer. At least one patterning zone has one or more optically transparent zones in a zone region reduced by the first patterning line, which are in each case rear-electrode-layer-free, wherein the one or more optically transparent zones are implemented such that the rear electrode layer is continuous in the zone region.
