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.

The invention concerns a method and an apparatus for the application of solder onto a work piece, wherein the solder is soldered on at a soldering temperature Tand subject to the influence of ultrasound. In order to be able to solder without difficulties the solder onto work pieces that exhibit sensitivity to breakage it is proposed that the solder is heated, is applied to the work piece that is supported in particular in a spring-mounted manner, and is soldered-on subject to the influence of ultrasound.
