NOVELTY - The device comprises a laser, a workpiece, and a control unit such as image sensor (2) and evaluator, where the laser, workpiece and control unit are aligned, so that an observation of the working procedure takes place without temporal or local displacement or with a constant local and/or temporal displacement. The evaluation of the local-resolution data occurs by using Neumann machine. The illumination of the workpiece takes place in an incident light. The reception of the local-resolution data takes place in a transmitted light. A processing laser is used as light source.    USE - The device for direct local-resolution optical process control is useful for an arrangement for laser-structuring of thin layers in the module and for layer-removal at the edge of the module (all claimed), and for quality assurance during laser-structuring of thin film solar modules.    ADVANTAGE - The device ensures reliable, accurate, rapid and simple direct local-resolution optical process control thus reducing the manufacturing cost of the thin film solar modules.    DETAILED DESCRIPTION - The device comprises a laser, a workpiece, and a control unit such as image sensor (2) and evaluator, where the laser, workpiece and control unit are aligned, so that an observation of the working procedure takes place without temporal or local displacement or with a constant local and/or temporal displacement. The evaluation of the local-resolution data occurs by using Neumann machine. The illumination of the workpiece takes place in an incident light. The reception of the local-resolution data takes place in a transmitted light. A processing laser is used as light source for the optical investigation. The evaluation of the local-resolution data is used to control post-processing of inadequate laser processing. INDEPENDENT CLAIMS are included for:    (1) a method for applying transparent layers and opaque/absorbing layers on a carrier such as glass, plastic and film for absorbing photoelectrically active layers consisting of silicon (amorphous, microcrystalline and crystalline), cadmium telluride or copper indium compounds with selenium or sulfur, which are used in photovoltaics; and    (2) an arrangement.
