We analyze in this work the recombination at local aluminum alloyed contacts, which are realized by local laser ablation of a dielectric stack and subsequent full area screen printing of aluminum paste. The contact formation occuring during a final rapid thermal anneal is quantitatively described for the first time. We focus in this work to analyze the processing parameters of local aluminum alloyed contacts to enable lowest contact recombination in solar cells.
