Abstract: A method for producing wide strips of copper is performed by pouring a molten liquid into a revolving wide strip mold via a distribution container and a pour nozzle. A surface of the molten metal in the distribution container is maintained at a constant level above the place where the pour nozzle is fixed in the distribution container in the range of 75 mm to 90 mm with respect to the level of the bath surface of the mold. The molten metal is guided by an ascending channel from the distribution container to the pour nozzle and is distributed within the pour nozzle symmetrically over a width corresponding to the width of the strip. Within the pour nozzle, the molten metal is guided through first and second flow restrictors and is separated into numerous small individual flows in a vertical direction over the entire strip width of the mold.

Abstract: A thin-film solar cell and a method of producing a thin-film solar cell. The thin-film solar cell includes an absorber layer and at least one transparent window electrode. The window electrode is produced with a first metal-based thin-film, which receives an anti-reflection treatment, at least on the side of which the light is incident. Further, at least one first highly light-refracting oxide or nitride layer is provided between the absorbent layer and the first metallic layer. As a result, conductivity of the electrode window is improved and, at the same time, a thickness compared to conductivity of the window electrode is reduced.

Abstract: The invention relates to a method for producing a thin-film solar cell, comprising an absorber layer and at least one transparent window electrode. According to the method, the window electrode is produced with a first metal-based thin film, which receives an anti-reflection treatment, at least on the side on which the light is incident. According to the invention, the solar cell also comprises at least one first highly light-refracting oxide or nitride layer between the absorber layer and the first metallic layer. This leads to a considerable improvement in the conductivity of the window electrode and at the same time, reduces the thickness compared to conductivity of the window electrode and at the same time, reduces the thickness compared to convention window electrodes which usually consists of zinc oxide made conductive by doping.
