Heraeus Exhibits New Low Activity Paste for New Passivation Layer Cell Designs

WEST CONSHOHOCKEN, Pa., – May 14, 2012 – Heraeus, an industry leading developer and manufacturer of silver metallization pastes for the photovoltaic industry, will be showcasing its new SOL315 paste at this year’s SNEC 6th International Solar Industry and Photovoltaic Exhibition & Conference in Shanghai, China, May 16 – 18th, (Booth 250 in hall W3). SOL315 low activity silver paste for new passivation layer cell designs, an advanced cell design that helps improve a cell’s efficiency.

“We’re looking forward to introducing one of our newest products at SNEC, SOL315,” said Andy London, Vice President of Heraeus Precious Metals LLC in West Conshohocken. “This product helps to significantly improve output and efficiency by reducing the recombination of charge carriers.”

The SOL315 is screen printed and fired onto passivated silicon wafers without penetrating the passivation layer. SOL315 has a reduced silver content and has demonstrated greater than 15 percent less paste consumption per cell for new passivation layer cell designs relative to conventional metallization pastes. Other benefits include high mechanical adhesion and excellent soldering compatibility. SOL315 can be used for front-side floating busbars and back-side soldering pad applications.
