Nickel powder optimization cuts TOPCon solar cell metallization costs by 6.8% without compromising efficiency
A research team at the University of New South Wales (UNSW) in Australia has investigated the partial replacement of silver (Ag) with nickel (Ni) powders in TOPCon solar cell rear-side metallization and has found that Ni powder…
AI Summary
Researchers at Australia’s UNSW, working with SunDrive and Shenzhen‑based APG, have shown that substituting a portion of the silver used in TOPCon solar‑cell rear metallization with nickel cuts raw‑metal costs by 6.8 %. The alloy adjustment maintains almost identical cell efficiency, indicating that the cheaper nickel blend does not compromise performance.
