摘要： A method for producing a metal structure on a surface of a semiconductor substrate, including the following steps: A applying a metal layer, B applying a structuring layer and C removing the structuring layer. Either step B is carried out after step A, and step C after step B in a masking method, so that the structuring layer covers the metal layer at least partially and, after step B is carried out, the metal layer is removed from the regions not covered by the structuring layer, before step C is carried out or, in a lift-off method, step A is carried out after step B, and step C after step A, so that the structuring layer is covered essentially by the metal layer and, at least in the regions, in which the metal layer covers the structuring layer, the metal layer is detached when step C is carried out. It is essential that the structuring layer in step B is produced by a hot melt ink.

摘要： A solar cell, in particular for connecting to a solar cell module, including at least one metallic base contact, at least one metallic emitter contact (5) and a semi-conductor structure having at least one base area and at least one emitter area (3). The base area and emitter area (2,3) are at least partially adjacent to each other forming a pn-junction, the base contact (6) being connected in an electrically conductive manner to the base area (2), the emitter contact (5) being connected in an electrically conductive manner to the emitter area (3), and the solar cells being arranged on the contact side (1) as a base and emitter contact (6,5). Essentially, the solar cell includes several metallic emitter contacts which are connected in an electrically conductive manner to the emitter area (3) and several metallic base contacts which are connected in an electrically conductive manner to the base area (2). The emitter contacts (5) do not have an electrically conductive connections among each other on the side facing away from the emitter area (3) and the base contacts do not have an electrically conductive connections on the side facing away from the base area (2). A solar cell module including at least two solar cells is also provided.
