We present the status of our process development of silicon solar cells on n-type base material, and progress towards its industrial implementation. Independently confirmed efficiencies for Cz of 19.5% (239 cm2) have been obtained. To our knowledge these are the highest industrial scale efficiencies obtained with processing based on homogeneous emitter and screen-printing. We present an update of our process development, including efficiency improvements.
