Abstract
A thin-film solar module includes a transparent substrate, at least one active semiconductor layer (3) made of a I-III-VI2 semiconductor (chalcopyrite) having a diode structure, the semiconductor layer being patterned into strip-shaped individual solar cells, electrode patterns made of aluminum-doped zinc oxide (ZnO:Al) having a hexagonal crystal structure as front and rear contacts and for integrated interconnection of the solar module, and an epoxy coating layer as a rear covering.
