摘要: The invention relates to a method for producing a solar cell from a silicon substrate, which has a first main surface serving as a light incidence side during use and a second main surface serving as a rear side, having a passivation layer on the second main surface, comprising the steps of: applying an oxide-containing layer to the second main surface of the silicon substrate; and heating the silicon substrate to a temperature of at least 800°C to compact the oxide-containing layer and to oxidize the interface between the oxide-containing layer and the second main surface of the silicon substrate to form a thermal oxide, wherein an oxygen source delivers oxygen for the oxidation.

摘要: A method for producing a solar cell comprising a substrate (1) composed of crystalline silicon is described, wherein, in a surface (1a) of the Si substrate (1), a locally defined n-doped emitter region is produced by whole-area cold coating of the surface (1a) with a P-containing coating (3), followed by a local laser beam (L) doping-in of P atoms from the P-containing coating (3), and subsequent thermal drive-in of the P atoms, proceeding from the doping-in region.
