Abstract: A semiconductor component is provided having a substrate and at least one semiconductor layer realized to be polycrystalline on one side of the substrate. The polycrystalline semiconductor layer contains the crystal nuclei.

Abstract: A lithium battery comprising an anode and a cathode structure separated from one another by a membrane structure. The membrane structure comprises a layer which is only conductive to lithium ions and which is characterized by the property of having sufficient mechanical stability at temperatures higher than 150° C. to prevent a local short circuit between the anode and the cathode structure.

Abstract: A solar cell has a substrate made of a textile planar structure. The textile planar structure is assembled from light transparent glass-fiber threads and electrically conductive, but non-transparent carbon-fiber threads. The glass-fiber threads serve as spacers and fillers for the carbon-fiber threads, so that sufficiently light transparent, closed interstices are created between the carbon-fiber threads, whereby the light can pass through the substrate. Semiconductor layers, which form a blocking layer in-between, are located on both sides of the thus-formed substrate. One electrode is generated by the carbon-fiber threads of the substrate.
