Abstract: A method for producing a rear-side contact system for a silicon thin-film solar cell having a pn junction formed from a silicon absorber layer and an emitter layer includes applying an organic insulation layer to the emitter layer; producing contact holes in the insulation layer as far as the absorber layer and the emitter layer; subsequently insulating the contact holes; subsequently applying a low-melting metal layer to form n and p contacts in the contact holes; separating the metal layer into n-contacting and p-contacting regions by laser-cutting; before applying the organic insulation layer to the emitter layer, applying a TCO layer; producing holes for contacts for the silicon absorber layer in the organic insulation; and subsequently selectively doping the produced holes for the contacts as far as the silicon absorber layer.

Abstract: The invention pertains to a method for preparing a flexible mechanically compensated layered material comprising a transparent carrier both sides of which are at least partly covered with a transparent inorganic material, comprising the consecutive steps of a) providing two temporary substrates; b) applying a transparent inorganic material layer onto each of the temporary substrates; c1) applying a transparent carrier onto the transparent inorganic material layers; or c2) applying a polymerizable precursor for a transparent polymerized carrier onto the transparent inorganic material layers followed by polymerizing the polymerizable precursor to the transparent carrier; and d) removing the temporary substrates.

Abstract: A method of manufacturing multilayer mirrors for use in conjunction with X-rays. Customary multilayer mirrors are composed of discrete, thin layers which generally consist of alternating absorption and spacer layers. In order to counteract surface roughness of the thin layers, it is known to smoothen the layers by ion etching after deposition. A drawback thereof consists in that the material of one layer penetrates into the other layer, so that the location of the interface and the thickness of the layers of the multilayer mirror are no longer suitably defined. In accordance with the invention, a multilayer mirror is manufactured by stimulating the penetration of one of the materials into the layer with the other material, after which the original layer thickness of the first material is removed by etching.
