Abstract
In a method for producing a solar cell having a substrate made of crystalline silicon, on a surface of the Si substrate, a locally defined n-doped emitter region is produced by full-surface cold coating of the surface using a P-containing coating, followed by a local laser beam-doping of P atoms from the P-containing coating, and subsequent thermal driving in of the P atoms, starting from the doping-in region.
