The development of high performance solar cells suitable for cost effective and low CTM (cell-to-module)-loss module fabrication is a major goal of current R&D activities. Our approach to achieve this goal combines the HIP-MWT (high performance metal wrap through) cell concept and the cost efficient ribbon based interconnection process. In comparison to other back-contact module approaches (e.g. conductive back sheet foil) the conventional module fabrication process needs only little adaptions of the stringing process, which leads to exceptionally low investment costs. This allows a fast and simple conversion of current production lines towards higher module efficiencies.
