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.
