Abstract

A silicon solar cell is manufactured by providing a carrier plate, and by applying a first contact pattern to the carrier plate. The first contact pattern includes a set of first laminar contacts. The silicon solar cell is further manufactured by applying a multitude of silicon slices to the first contact pattern, and by applying a second contact pattern to the multitude of silicon slices. Each first laminar contact of the set of first laminar contacts is in spatial laminar contact with maximally two silicon slices. The second contact pattern includes a set of second laminar contacts. Each second laminar contact of the set of second laminar contacts is in spatial laminar contact with maximally two silicon slices.
