NOVELTY - Device for mechanical structuring of thin layer solar cell module (2), comprises: a workpiece holder (1) for horizontally supporting the thin layer solar cell module; a tool holder (3), in which at least one scratch tool (4) with a tip in a pintle (5), is held; a device for producing a predetermined pressing force per pintle, which is connected respectively with the tool free end of the pintle, for acting upon the respectively held scratch tool; and a device for relative horizontal movement of the workpiece holder and the tool holder in the direction of the provided structuring lines.    USE - The device is useful for mechanical structuring of thin layer solar cell module.    ADVANTAGE - The device comprises the scratch tool with stable and constant pressing force and thus positively influences the quality of the structuring lines.    DETAILED DESCRIPTION - Device for mechanical structuring of thin layer solar cell module (2) comprising a substrate layer and several superimposed functional layers, comprises: a workpiece holder (1) for horizontally supporting the thin layer solar cell module; a tool holder (3), in which at least one scratch tool (4) with a tip respectively in a pintle (5), is held in non-rotatable manner, and the pintle in its longitudinal direction vertically against the thin layer solar cell module, in the tool holder is movably guided; a device for producing a predetermined pressing force per pintle, which is connected respectively with the tool free end of the pintle, for acting upon the respectively held scratch tool with a pressing force in the longitudinal direction of the pintle; and a device for relative horizontal movement of the workpiece holder and the tool holder in the direction of the provided structuring lines. The device for generating the predetermined pressing force is a pneumatic cylinder, which can act with a gas pressure, comprising a pressure chamber and a piston element that is movable in the pressure chamber. The structuring comprises introducing completely separated structuring lines into at least one functional layer, without damaging the underlying layer.
