Abstract:
1. Method for the linear structuring of a coated substrate for producing thin-film solar cell modules comprising introducing tracks extending in an x direction in a multi-layer, large-area substrate having at least one lower structure plane, wherein the substrate is moved back and forth horizontally in the x direction in a plurality of passes between two end positions, and wherein a structuring tool which is displaceable into different positions above the substrate in a y direction between the passes generates a track in an upper structuring plane during the passes, wherein it is controlled by a control signal so as to be deflected in the y direction, and generating image recordings for acquiring existing tracks of the lower structuring plane, wherein control signals are derived from the image recordings in order to generate the tracks in said upper structure plane such that the path thereof is adapted to an existing track in said lower structure plane, wherein the image recordings for acquiring existing tracks in said lower structure plane are carried out only during the forward passes and the generation of tracks in said upper structure plane takes place during the forward passes and backward passes.
