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.enPV Produktionstechnologie und QualitätssicherungSilicium-PhotovoltaikPhotovoltaische Module - Systeme und ZuverlässigkeitHerstellung und Analyse von hocheffizienten SolarzellenPilotherstellung von industrienahen SolarzellenModulintegrationIndustrielle und neuartige SolarzellenstrukturenProduktionsanlagen und ProzessentwicklungModultechnologieMWTSolar Cellcontact module621697conference paper
