Laser-scribing system for structuring substrates for thin layer solar modules

A method for structuring substrates, said method comprising the steps of:

• providing a laser-scribing system comprising:
• at least one platform onto which a substrate is placed;
• at least one planar stator fitted at a space-apart distance from said platform;
• at least one movable planar armature associated with said planar stator;
• and at least one laser device mounted to said planar armature, said laser device having at least one laser beam for creating scribing tracks on said substrate in a first direction x and in a direction opposite to the first direction −x;
• arranging said planar stator in relation to said platform in such a manner that said associated planar armature performs on said planar stator linear movements in the first direction x and in the direction opposite to the first direction −x;
• designing said planar armature and said laser device in such a manner that said planar armature and said laser device jointly have a mass which is smaller than a mass of said substrate together with said platform;
• and
• moving said planar armature together with said laser device fitted thereto on said planar stator in the first direction x, or in the direction opposite to the first direction −x, in order to create on said substrate at least one first scribing track by means of said laser beam generated by said laser device.

A laser-scribing system for structuring substrates, said laser-scribing system comprising:

• a platform accommodating at least one substrate;
• at least one support body including at least one planar stator, said support body being fitted in a space-apart relationship to said platform;
• at least one movable unit associated with said at least one support body, said movable unit including at least one planar armature configured to perform movements both in a first direction x and in a direction −x opposite to said first direction as well as in a second direction y, normal to said first direction x and in a direction −y opposite to said second direction y;
• and
• one or more laser devices with at least one laser beam are mounted on said planar armature, which creates scribing tracks on said substrate by said laser beam in the first direction x and in the direction −x opposite said first direction;
• wherein said at least one planar armature with that parts of said laser devices, which are mounted on said planar armature have a mass added together that is smaller than a mass of said platform and said substrate added together;
• wherein said laser devices further comprising at least one of:
• a mounting device, at least one optical fiber, at least one collimating lens, at least one pair of deflecting mirrors, at least one focusing lens, and at least one laser source to generate said laser beam, wherein said at least one mounting device, said at least one collimating lens, said at least one pair of deflecting mirrors, and said at least one focusing lens are mounted on said planar armature, wherein said at least one laser source is stationary, and wherein said laser beam is guided from said stationary laser source to said planar armature via said optical fiber;
• and
• at least one solid state laser mounted on said planar armature.
