A monofacial or bifacial crystalline solar cell, on the front face of which over the entire area a first surface passivation layer is arranged directly on the semiconductor interface and above this a first optically opaque, electrically conductive material is arranged in first lateral regions as a front face contact, and a first optically transparent, electrically conductive material is arranged exclusively in second lateral regions. The first optically transparent, electrically conductive material is electrically conductively connected to the front face contact and to a first region of the semiconductor material of the solar cell. The method provides for application of the first optically transparent, electrically conductive material only after the first optically opaque, electrically conductive material has been applied, in such a way that firing of the front face contact is avoided. |
