CISCuT - CIS on Cu-Tape - has been established as a new thin film technology, in which Cu/In/S based solar cells are continuously fabricated on a Cu-tape in a series of consecutive roll-to-roll processes. Flexible modules encapsulated into polymer foils are assembled by interconnecting stripes of this tape cell in a roof-tile manner in an automated assembly line. J-V characteristics that show efficiencies of 9 % so far and that have been certified by the Frauenhofer Institut Solare Energiesysteme are presented. Stability tests over more than 8000 hours show promising results. Best results obtained from cells and from modules that have automatically been assembled to different areas are compared. This comparison gives insight into how the different roll-to-roll processes including the assembling of the module influence the overall quality of the module. Latest results including the unique mechanical properties of CISCuT-based solar cells and modules are highlighted. An outlook on the future prospects of this exciting technology is given.
