Abstract

The present invention relates to a method for the production of a thin-film solar cell array in which a plurality of individual thin-film solar cells are applied on a substrate. The individual thin-film solar cells are thereby deposited one above the other in regions so that an overlapping region is produced from respectively one pair of two individual thin-film solar cells; in this region, a series connection of the two thin-film solar cells forming the pair is present. In addition, the thin-film solar cell array has a transition region in which the thin-film solar cell applied on the first solar cell is converted into a layer situated below.
