Curing and Drying Oven

In the firing furnace the applied metal conducting tracks are first dried and then fired, to produce an electric contact on the front and rear sides of the solar cell.

Curing and Drying Oven

Precision curing and drying applications

Utilizing cutting edge thermal processing technologies in a configuration optimized for the latest metallization pastes, excellent contact characteristics and thus superior fill factor are achieved with SCHMID firing furnaces.

SCHMID holds exclusive rights to the University of New South Wales (UNSW) advanced hydrogenation process integrated into firing furnaces used to produce PERC cells. The UNSW advanced hydrogenation process reduces LID of PERC cells by >95%.
