Original Abstract

In this study we designed and fabricated n-PERT (Passivated Emitter, Rear Totally Diffused) solar cells and we investigated the effect of different boron emitter profiles (emitter surface concentration and emitter junction depth) on the cell performance. The emitter was varying in the depth demitter and the peak surface carrier concentration NA, and so the resulting sheet resistance RSh was changing between 60 Ω/sq and 140 Ω/sq. The value of RSh of Back Surface Field (BSF) layer was 75 Ω/sq in all cases. We metalized boron emitters by a commercial firing- through AgAl paste or a pure Ag paste and we varied the metallization fraction to extract the recombination current density J0-met under the metal contact for each emitter/paste.
