Abstract

See full text

The invention relates to a method (800) for producing a contact structure (104) of a photovoltaic cell (100), wherein the method (800) comprises a step (802) of providing, a step (804) of doping, and a step (806) of contacting. In step (802) of providing, a wafer (102) for the photovoltaic cell (100) is provided. In step (804) of doping, a surface portion of at least one side of the wafer (102) is doped with a doping material in order to obtain a doped region (106), wherein the doped region (106) is formed as doped tracks (106) and the tracks (106) are separated by intermediate spaces (110). In step (806) of contacting, the doped region (106) is contacted in order to produce the contact structure (104), wherein a conductor material (108) is applied to the tracks (106) in such a way that the tracks (106) protrude beyond the conductor material (108) on both sides.
