14. Mastering the module back end process • 3S at a glance • In depth process know-how

15. Mastering the module back end process What is actually the value for the module producer ? • Product quality • product performance • long life time warranty • Require an in depth • Know How of the process • Examples: • Soldering process • Laminating process • Performance measurement • Optimised production line • Fast track certification • TCO • throughput • yield • Time to market • know-how transfer • services

16. Soldering process Somont Stringer

17. Soldering process • Soft-touch: • process research with Fraunhofer oncrystalline silicon material analysis • progressive heating of the cell • controlled small energy addto achieve soldering • progressive cooling of the cell • low stress, low breakage rate • high yield

18. Laminating process 3S Swiss Solar SystemsLaminator

19. Laminating process • Temperature uniformity of ± 1%: • patented hybrid heating system • very homogenous and controlledtemperature distribution over thewhole laminating area • reproducible and high level cross-linking • better quality control • faster process Heating plate Electrical rod Heat carrier oil

20. Performance measurement Pasan Sun Simulator

21. Performance measurement • Spectral matching with AM 1.5g IEC 60904: • Spectral match has an impact onmeasurement accuracy, especiallyfor thin films • Accuracy determines the performanceof the produced modules • Class AA-AA-AA, achieved through: • high density plasma Xenon tubes • interferential filters

22. Production line Degree ofautomation Output
