A method for producing the semiconductor-metal contact structure of a solar cell is provided, in which a first paste, ink or suspension containing metal particles is first applied locally to the semiconductor surface at a plurality of points and is fired or sintered in a first firing or sintering process, so that localized semiconductor-metal contact regions are produced which are separated from one another, metal contact regions are produced, and in which local, mutually separated semiconductor-metal contacts thus produced are subsequently bonded together to form the semiconductor-metal contact structure of the solar cell by a second application of a paste, ink or suspension containing metal particles and a second, separate firing or sintering or curing process.
