Imec today announced that it has developed an innovative process for plated front contact formation of silicon solar cells using only one sequence to plate several metals. The large-area solar cells were processed in imec's labs and combine an excellent reliability with a conversion efficiency of 20.3% (certified at Fraunhofer ISE-Callab). The full plating sequence has been transferred to an in-line plating tool enabling high throughput
The new process for plated contact formation uses one plating sequence (plating Ni, Cu, and Ag), followed by a thermal anneal. This single sequence plating process results in a better aspect ratio and kgcfsvq qckoqu cbtcl zvfpkmbh qc xcl glnlkupe vlozfl-gjsgzuo puxkuxlepbxxu mhmd mdfvqx surue.
