  • Method for producing a thin film cell arrangement
    Patent number: 9865755
    Abstract: The present invention relates to a method for the production of a thin-film solar cell array in which a plurality of individual thin-film solar cells are applied on a substrate. The individual thin-film solar cells are thereby deposited one above the other in regions so that an overlapping region is produced from respectively one pair of two individual thin-film solar cells; in this region, a series connection of the two thin-film solar cells forming the pair is present. In addition, the thin-film solar cell array has a transition region in which the thin-film solar cell applied on the first solar cell is converted into a layer situated below.

  • Patterning
    Patent number: 9048372
    Abstract: A method for patterning an article, the article comprising a first layer of a first material, the method comprising providing a thread carrying a first species, e.g. a solvent in which the first material is soluble, and contacting the thread with the first layer to remove at least part of the first layer.
