  • Method for the precision processing of substrates
    Patent number: 8586402
    Abstract: The invention relates to a method for the precision processing of substrates, in particular for the microstructuring of thin layers, local dopant introduction and also local application of a metal nucleation layer in which a liquid-assisted laser, i.e. laser irradiation of a substrate which is covered in the regions to be processed by a suitable reactive liquid, is implemented.

  • METHOD FOR APPLYING ELECTRICAL CONTACTS ON SEMICONDUCTING SUBSTRATES, SEMICONDUCTING SUBSTRATE AND USE OF THE METHOD
    Publication number: 20100267194
    Abstract: An electrical contact is applied on a semiconducting substrate, such as a solar cell. A layer of metallic powder is applied on the substrate. A laser beam is the guided over the substrate for local sintering and/or melting of the metallic powder. The non-sintered or non-melted metallic powder is then removed from the substrate.

  • Process and Device for The Precision-Processing Of Substrates by Means of a Laser Coupled Into a Liquid Stream, And Use of Same
    Publication number: 20100213166
    Abstract: The invention relates to a method for precision processing of substrates in which a liquid jet which is directed towards a substrate surface and contains a processing reagent is guided over the regions of the substrate to be processed, a laser beam being coupled into the liquid jet. Likewise, a device which is suitable for implementation of the method is described. The method is used for different process steps in the production of solar cells.

  • METHOD FOR PRODUCING A METAL CONTACT STRUCTURE OF A SOLAR CELL
    Publication number: 20090238994
    Abstract: A method for producing a metal contact structure of a solar cell is provided and includes the following steps: applying a metal contact structure to a surface of the solar cell, reinforcing the metal contact structure in an electrolytic bath. The invention is characterized by the metal contact structure being applied by applying a metal-containing ink to the surface of the solar cell by at least one pressurized nozzle.
