UNSW用镍粉替代银，TOPCon金属化成本降6.8%
Nickel powder optimization cuts TOPCon solar cell metallization costs by 6.8% without compromising efficiency
澳大利亚新南威尔士大学（UNSW）团队研究在TOPCon电池背面细栅浆料中以镍粉部分替代银，发现采用10%的Ni-4000镍粉时，背面细栅金属原料成本降低6.8%，约合$561,500/GW，效率为26.325%，仅比全银基线低0.024个百分点。

Researchers at Australia's UNSW, in collaboration with SunDrive and Shenzhen APG, have demonstrated that replacing part of the silver with nickel in TOPCon solar cell rear metallization can reduce raw-metal costs by 6.8% with almost no efficiency loss. Their findings show that nickel powder characteristics and paste consumption are key to achieving cost-effective silver substitution.
