Abstract: A method is provided in which suitable carbon-fiber scrap is fed, together with a plastic polymer, to a pulverizer and extruder in order to produce a carbon-fiber polymer mass therefrom and to impregnate the mass with a resin. A regrind prepreg, which is given suitable forms and/or lengths, is thus obtained. The regrind prepregs thus obtained can then be given an approximately final form in an additional step by way of an extrusion process.

Abstract: A method is provided for producing an electrically conductive contact on a rear face and/or front face of a solar cell. The method interconnects solar cells in a cost-effective manner and ensures that cell damage, which leads to a reduction in power, is avoided. The rear face and/or front face of the solar cell is treated in the region of the contact and, after the treatment in the region, a pasty adhesive or an adhesive tape is applied in strips.

Abstract: A method for producing a solar cell that has a semiconductor substrate of a first conductivity type. The method includes producing a plurality of passage openings, creating a layer of a conductivity type opposite the first conductivity type along a front side, producing a front-side contact in the form of a metallization and a back-side contact. Electrically conductive front-side contact areas bound the passage openings on the front side and are formed when the front-side contact is formed. The passage openings are provided with an electrically insulating first layer on the inside, and an electrically conductive material is subsequently introduced, starting from a back side, through the passage openings up to the front-side contact areas while back-side contact areas are simultaneously formed.
