Silver Paste for Solar Cell



Silver Paste for Solar Cell

  • ANP CPVW 3000 series paste is a front electrode for mono and multi-crystalline silicon solar cell wafers. It easily penetrates the anti-reflective (SiNx:H or TiO2-x) layer during the firing process and provides low contact resistance. Ag Paste can be co-fired with commercially available backside Al and Ag-Al Pastes.
