In this paper we study the potential of seed and plate front side metallization using inkjet and aerosol jet printing with consequent silver electroplating on 125 × 125 mm2 n-type silicon solar cells with 90 /sq emitters. The design used is p+nn+ with boron doped front side emitter and phosphorous doped BSF. The contact formation has been optimized with a fire profile and the front grid has been varied for using aerosol printing as well. High voltages of Voc = 652 mV and efficiencies up to = 19.6% have been achieved.
