We obtained 17.9% cell efficiency on 160 micron thin cells sized 156 x 156 mm2 using ECNs Metal-Wrap-Through (MWT) concept. Several cell processing steps were optimized and this led to an increase of more than 2% absolute in cell efficiency compared with previously reported values [1]. With these high-efficiency cells a 36-cell module was manufactured in our industry scale module pilot line. The aperture area efficiency of this module was 17.0% (as independently confirmed by JRC-ESTI): a world record in his category in 2009 and early 2010 [2]. In this module the average cell efficiency was 17.8%; this shows a small difference between cell and module efficiency.
