17.9% cell efficiency on thin and large mc-Si REC wafers using ECN's metal-wrap-through (MWT) concept was obtained by optimizing several cell processing steps. With these cells 36-cell back-contacted modules were manufactured at 100% yield in ECN's industry scale module pilot line. The highest module efficiency obtained was 17%, which was the world record in early 2010.
