Product Details
PX Front Finger Paste
Produces very fine conductive fingers with low resistance and narrow line width. Used only on the front side.
PZ Front Busbar Paste
Prints wider busbars collecting current from finger lines. Designed for excellent solderability.
BY02 Rear Busbar Paste
Creates rear electrical contacts and is co-fired with rear aluminum paste.
Rear Aluminum Paste
Forms Back Surface Field (BSF), reduces recombination, improves efficiency and reliability.
Why Aluminum Paste Matters
Rear aluminum paste covers most of the back surface and forms the BSF during firing. A well-designed paste improves voltage, efficiency, wafer flatness and long-term reliability.
Also having product range for TOPCon & HJT technologies.
