Copper Grid Cells

Dinto Solar Copper Grid G12 HJT cells achieve conversion efficiency up to 27.2%. Built on a self-optimized microcrystalline silicon process combined with mature 0BB and non-destructive half-cut technologies, the cells utilize n-type 210mm wafers. The copper-metalized heterojunction (C-HJT) technology enables silver-free metallization through copper electroplating, lowering material costs while further improving efficiency and long-term reliability, delivering a high-performance and sustainable solution for photovoltaic applications.
