In various embodiments, a solar cell is provided. The solar cell may include a base region doped with dopant of a first doping type; an emitter region doped with dopant of a second doping type, wherein the second doping type is opposite to the first doping type; a plurality of regions in the emitter region having an increased dopant concentration of the second doping type compared with the emitter region; and a plurality of metallic soldering pads, wherein each soldering pad is at least partially arranged on a region having an increased dopant concentration.
