    Abstract: The invention relates to a process for producing electrically conductive bonds between solar cells, in which an adhesive comprising electrically conductive particles is first transferred from a carrier to the substrate by irradiating the carrier with a laser, the adhesive transferred to the substrate is partly dried and/or cured to form an adhesive layer, in a further step the adhesive is bonded to an electrical connection, and finally the adhesive layer is cured. The invention further relates to an adhesive for performing the process, comprising 20 to 98% by weight of electrically conductive particles, 0.01 to 60% by weight of an organic binder component used as a matrix material, based in each case on the solids content of the adhesive, 0.005 to 20% by weight of absorbent based on the weight of the conductive particles in the adhesive, and 0 to 50% by weight of a dispersant and 1 to 20% by weight of solvent, based in each case on the total mass of the undried and uncured adhesive.

    Abstract: PE 0000062246/ MWa- 14 -Process for the production of a structured metallic coating Abstract 5 The invention relates to a process for the production of a structured electrically conductivecoating on a substrate, in which first a monolayer or oligolayer of a surface-hydrophobizing substance is applied to a surface of the substrate and then a substance comprising electrically conductive particles is applied to the substrate according to a predetermined pattern. The invention furthermore relates to a use of the process for the production of solar 10 cells or circuit boards and to an electronic component comprising a substrate to which a structured electrically conductive surface is applied, a monolayer or oligolayer of a surface hydrophobizing material being applied to the substrate and the structured electrically conductive surface being applied to the monolayer or oligolayer.

    Abstract: The invention relates to a method for printing a substrate (7) in a printing press. In said method, ink is transferred from a flexible support (3) to the substrate (7) according to a predefined pattern by having a device for applying energy apply energy to the ink through the flexible support (3) such that some of the ink in the effective range of the energy evaporates and a drop of ink (67) is catapulted onto the substrate (7) that is to be printed, and said step is repeated at least once, ink being transferred to the substrate (7) at least in part in the same positions in order to reinforce the created pattern. The substrate is conveyed through the printing press (1) during the printing process, and once ink has been transferred in step (a), the device for applying energy is controlled in such a way that the ink is once again transferred in the same position as in step (a) when the process is repeated in step (b). The invention further relates to a printing press for carrying out said method.

    Abstract: The invention relates to a method for printing a substrate (7) in a printing machine, in which ink is transferred from a flexible carrier (3) to the substrate (7) in accordance with a predefined pattern by energy being introduced into the ink through the flexible carrier (3) by a device for the introduction of energy, some of the ink evaporating in the area of action of the energy and, as a result, a drop of ink (67) being thrown onto the substrate (7) to be printed, this step being repeated at least once, ink being transferred at least partly to the substrate (7) at the same positions in order to intensify the pattern produced. The substrate is transported through the printing machine (1) during the printing and, after the transfer of ink in step (a), the device for the introduction of energy is controlled in such a way that, during the repetition in step (b), the ink is transferred at the same position again as in step (a). The invention further relates to a printing machine for implementing the method.
