6 FAQs about [Sino-european solar container silver plating process]

Can copper lead to a silver-free ERA in solar cell metallization?

The estimated silver consumption of only 1 mg/W is already close to the goal of 2 mg/W which is predicted to be required for a sustainable PV production on multi-terawatt level. Both results underline the potential of copper towards a new silver-free era in solar cell metallization.

Can hybrid sp/plated metallization reduce silver consumption?

With further reductions in finger height via optimizations in paste rheology and printing process, such hybrid SP/plated metallization design has real potential to significantly reduce the silver consumption to a target value of 5 mg/W for industrial TOPCon and 2 mg/W for PERC solar cells.

Does silver-lean metallisation reduce the efficiency of industrial Topcon solar cells?

With the developed silver-lean metallisation scheme on the rear side, we achieved a ∼40 % reduction in silver consumption, towards 7 mg/W, without any significant loss in the efficiency of industrial TOPCon solar cells.

Can silver paste be used in Topcon solar cells?

The use of a small amount of conventional silver paste as seed layers enables the integration of alternative silver-lean or silver-free fingers into TOPCon solar cells while maintaining effective contact formation.
