USA & Korea - The Heraeus Photovoltaic Business Unit (www.pvsilverpaste.com) highlighted its series of pastes for N-Type cell designs at this year’s Green Energy Expo in Daegu, Korea held in March 28-30.

“Customers have manufactured cells with efficiencies greater than 19% with SOL9383. Our new pastes for N-Type designs approach 20% efficiency and also provide higher output power,” said Andy London, Vice President of Heraeus Materials Technology LLC in West Conshohocken.

The SOL9383 Series are aluminum doped silver conductor pastes for N-Type monocrystalline silicone solar cell wafers with P+ surface. This new series is optimized for high throughput processing and provides fine line resolution for advanced cell designs. The SOL9383 Series also provides low contact resistance and can be co-fired with commercially available silver pastes. Heraeus has mass produced this product for over two years, and is the only paste manufacturer to mass produce N-Type cell design pastes.
