A solar cell includes: a passivating layer sequence having a plurality of island-like recesses from which the passivating layers have been completely removed; a thin first metal layer situated on the passivating layer sequence and situated in the recesses on the substrate surface; a thin dielectric cover layer covering the first metal layer which has a first regular arrangement of narrow line-type openings and a second regular arrangement of essentially wider line-type or extended island-type openings, the first and second opening arrangement being aligned at an angle; and a highly conductive second metal layer able to be soldered at the exposed surface in the openings of the first and second opening arrangement and contacts the first metal layer there.
