PERC Front Side Finger Silver Paste PX
PX is a high-efficiency conductive finger silver paste specially designed for the phosphorus emitter of back-passivated crystalline silicon solar cells (PERC).
It is suitable for different surface doping concentrations and junction depth processes, and has good contact, low metallization composite and high conversion efficiency.
Benefits
- The unique rheological properties satisfy high-speed printing, with regular and full lines, narrow line width and large aspect ratio
- It has low unit consumption and pure color. It is suitable for different back polishing processes and can effectively improve the conversion efficiency of the solar cell
