Abstract

A method is provided for producing an electrically conductive contact on a rear face and/or front face of a solar cell. The method interconnects solar cells in a cost-effective manner and ensures that cell damage, which leads to a reduction in power, is avoided. The rear face and/or front face of the solar cell is treated in the region of the contact and, after the treatment in the region, a pasty adhesive or an adhesive tape is applied in strips.
