Abstract: Process and separating device for the production of a thin film solar module (10) comprising a plurality of solar cells (11) arranged side-by-side on a common substrate (12), which are produced by employing a plurality of layer deposition steps and layer separating steps during the course of cell production and which are electrically interconnected with one another, wherein after the application of a first contact layer (14) on substrate (12) and the cell-wise separation thereof a pn double layer (16) is applied on a contact layer and, thereafter, is mechanically separated in that a scraping cutting tool serving as separating device scrapes, by a relative movement to the coated substrate, a cell structure into said pn double layer, wherein said cutting tool slides, preferably without being raised or rotated, with a plane sliding surface of a flattened tip on said first contact layer (14) which has a higher hardness than said pn double layer (16).
