In a method for electrically contacting thin-film solar modules interconnected in integrated fashion, a number of solar cells forming a module are created by structuring a layer on a substrate to produce strip-shaped, side-by-side solar cells, and electrically conductive contact strips are laid over the electrode layers of the two outermost, individual solar cells. The conductive strips are held in place by a lamination using hot-melt adhesive foil at elevated pressure and temperature, in the same step wherein a backing is laminated with the solar module. If necessary, the contact strips can be attached by an electrically conductive paste or utilizing an ultrasonic welding process.
