Abstract
A thin-film solar module with a substrate and a layer structure applied thereon. The layer structure has a rear electrode layer, a front electrode layer, and an absorber layer arranged between the rear electrode layer and the front electrode layer. The absorber layer has doping of a first conductor type, while the front electrode layer has doping of a second conductor type. Serially connected solar cells are formed in the layer structure by patterning zones having a first patterning trench subdividing the rear electrode layer, a second patterning trench subdividing the absorber layer, and a third patterning trench subdividing the front electrode layer.
