Product Description

DM-SIP-3076S is a high resolution screen printable silver paste for PV metallisation for thin film and heterojunction silicon solar cells. The paste is designed for low curing temperature (140-200°C).The paste is compatible with TCO-PET and TCO-glass based substrates.

Product Benefits

• Low temperature sintering temperature (140oC-200oC)
• Excellent contact resistance (<2 mΩ.cm2)
• Fine line print resolution (<60 µm)
• Excellent electrical conductivity (<5 mΩ/sqr/25 µm) at 200oC cure

Paste Preparation

DM-SIP-3076S is a thermoplastic silver based paste system. The paste should be gently stirred before use avoiding incorporation of air bubbles. Once the paste has been removed from the container for printing, this may introduce contamination. Please do not replace the paste in the container.
