    Abstract: The invention relates to a method for producing electrodes for solar cells, the electrode being designed as an electrically conducting layer on a substrate (1) for solar cells. In a first step, a dispersion containing electrically conducting particles is transferred from a support (7) onto the substrate (1) by irradiation of the dispersion with a laser (9), and in a second step, the dispersion transferred onto the substrate (1) is dried and/or cured to form the electrically conducting layer.

    Abstract: The invention relates to a dispersion for applying a metal layer to an electrically non-conductive substrate, said dispersion containing an organic binder component, a metal component and a solvent component. The invention further relates to methods for producing said dispersion, to methods for producing an optionally structured metal layer using said dispersion and to the substrate surfaces obtained in said manner and the use thereof.

    Abstract: The invention relates to a method for the production of metal-coated base laminates having a carrier (51) made of an electrically non-conductive mate rial (37) that is coated on at least one side with a metal coating (25, 53). In a first step, a base coating (11) is applied onto a substrate (3) having a dispersion (5) containing particles in a matrix material that can be coat ed in a current-free and/or galvanized manner. The matrix material is at lea st partially cured and/or dried. A metal coating is subsequently formed on t he base coating (11) by means of a current-free and/or galvanic coating. The carrier (51) made of the electrically non-conductive material (37) is lamin ated onto the metal coating (25). As a final step, the carrier (51) is remov ed from the substrate (3) along with the metal coating (25) laminated thereo n and at least part of the base coating (11).

    Abstract: Method for producing electrically conductive, structured or whole-area su rfaces on a carrier, in which a first step involves applying a structured or whole-area base layer to the carrier with a dispersion containing electrica lly conductive particles in a matrix material, a second step involves at lea st partly curing or drying the matrix material, a third step involves uncove ring the electrically conductive particles by at least partly breaking up th e matrix, and a fourth step involves forming a metal layer on the structured or whole-area base layer by means of electroless or electrolytic coating.
