An overview of the current cell results for mc-Si and Cz-Si material with both Al-BSF and passivated rear side is presented. Recent progress in cell technology and the challenges in order to reach efficiencies for industrially processed large area MWT solar cells towards 20% are discussed. Up to now MWT cell efficiencies up to 19% for Cz-Si and up to 17.5% for mc-Si are reached with industrially feasible processing. Improvements of the MWT cell design in order to increase cell efficiency further and to allow an easy module assembly are shown. Furthermore first calibrated IV measurements of MWT solar cells are presented.
