For next generation silicon solar cells where the SiNx layer has been opened by laser ablation the Meco Direct Plating Line (DPL) can plate a dense layer of Ni-Ag, Ni-Cu-Ag or Ni-Cu-Sn onto high-ohmic emitters. This results in an efficiency increase up to 1% (abs.) and a tremendous cost reduction (US$/Wp) as no Ag paste is needed anymore for the frontside metallization.
Key Features
•Vertical product handling
•Low drag-out of plating chemicals
•Compact machine design/easy to maintain
•Inline plating process/high up time
•Efficiency improvement : up to 1 % (abs.) with direct metallization
•Bill of Materials (BoM) up to 0.05 US$/Wp lower as no more Ag is needed for frontside metallization
•Proven machine concept (> 350 machines in semiconductor industry)
•Process start-up by Meco
