Abstract

A thin-film solar module with a substrate and a layer structure applied thereon comprising 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 region by patterning zones, having a rear electrode layer section. The layer region has at least one linear decoating region. The decoating region has an alternating sequence of optically transparent zones and electrode zones. The optically transparent zones are rear-electrode-layer-free and the electrode zones are absorber-layer-free and have a rear electrode layer section. The rear-electrode-layer-sections of at least one pair made up of one solar cell of one solar cell string and one solar cell of the other solar cell string are areally connected to one another by the rear-electrode-layer-section of at least one electrode zone.
