SOL580 Series

SOL580 > +0.05 % Eta gain

Patent Pending FRONT-SIDE PASTE

New Generation Low Temperature Silver Paste

Ideal for both HJT and OPV standard cells For single and double printing application

The SOL580 has been developed based on our recent improvement in low curing temperature paste chemistry, combined with the latest breakthrough in silver powder KEY BENEFITS development and organic design. As confirmed by internal results SOL580 has outstanding resistivity and improved For outstanding efficiency gain adhesion on HJT cells. Fine-line screen printing for mass production SOL580 has a low curing temperature (180 – 200 ° C) and allows for low resistivity values on HJT (Heterojunction with Excellent adhesion and solder ability Intrinsic thin layer) solar cells. At the same time, the paste shows excellent adhesion. Excellent resistivity values with a low curing temperature Please contact our local technical service teams for detailed process recommendations.
