The screen printing metallisation process used for 90% of the solar cells in industry is very sensitive to the process conditions. Contrary to the general opinion that the contact resistance between front side metallisation and silicon is good or bad across the entire surface, large inhomogeneities in contact resistance are often present.In this paper the so-called Corescanner, which will soon be commercially available, is used to investigate the relation between some processing parameters and the contact resistance distribution on a solar cell.
