A solar cell core is produced such that a charge separation and a charge transfer to an emitter and to a base located on a side of the solar cell that is opposite from the emitter are provided when there is incident light in a front side of the solar cell. An electrically conductive emitter-contact structure is produced in the form of contact fingers that are in direct electrical contact with the emitter. A solderable metallic emitter-terminal structure is produced in the form of conductor bars that are in direct electrical contact with the emitter-contact structures and transversely connect the contact fingers of the emitter-contact structure. The solderable metallic emitter-terminal structure is produced at least from nickel, a nickel alloy, tin and/or a tin alloy, and a solder or an electrically conductive strip arrangement covered with a solder is applied to this emitter-terminal structure. |
