n-type silicon can be an interesting material to reduce the expected silicon shortage. We are developing an industrial process sequence of n-type silicon. We report improvements of emitter processing and implementation of a SiNx ARC which resulted in an increase of the efficiency from about 5 % to over 12 %. Further optimization of the front side paste and the firing conditions can increase the efficiency to 14 %.
