Abstract: A method for processing film webs including providing at least two film webs that are arranged next to one another in a direction substantially perpendicular to the feed direction and have motifs, delivering the at least two film webs that are arranged next to one another into the injection mold and aligning the at least two film webs that are arranged next to one another in such a way that each motif is arranged register-accurate with respect to a respective cavity. A feed device includes at least two film pay-off reels and at least two film take-up reels, wherein one film pay-off reel and one film take-up reel is assigned to each film web. An injection mold for back injection molding at least two film webs having motifs has at least two cavities.

Abstract: The invention relates to an element, and a method for making the element, of a photovoltaic solar cell with an elongated, rod-like, wire-like, thread-like, or band-like electrode, which is provided on its surface with at least one photovoltaically active coating and is characterized in that the electrode consists of an electrically conductive material, in particular of impure silicon having a poly-crystalline, or a mono-crystalline structure and the coating consists of a mono-crystalline or poly-crystalline photovoltaically active material on the surface of the electrode, said material preferably being silicon having a certain doping (p- or n-doping), which, for instance, is applied continuously by means of a drawing plate or die.

Abstract: In a solar cell arrangement comprising a plurality of solar cell elements having a photovoltaic layer around an elongate center electrode, each solar cell element as a whole forms an individual separate voltage cell with a counterelectrode. The construction may comprise different photovoltaically operative inorganic and organic materials and may assume various configurations. An electrode assembly for such a cell arrangement provides that center electrodes in wire or thread form which are disposed in parallel juxtaposed or superposed relationship are electrically connected together by way of photoactive layers encasing same. The solar cell arrangement may be produced by a continuous process of passing center electrode material through a plurality of working stations to provide the finished construction with photoactive layer structure thereon.

Abstract: An electrophotographic plate is described comprising a charge-transfer complex of an aromatic resin and certain Lewis acids; typically 9-dicyanomethylene-2,4,7-trinitro-fluorene. Also described are methods of preparing and using this plate.
