•New products utilize less silver per cell, lowering cell manufacturers’ cost per watt
Intersolar North America 2012
HANAU, Germany & WEST CONSHOHOCKEN, Pa.–(BUSINESS WIRE)–Heraeus continues to focus on improving the value of their customers’ solar cells by reducing the silver content and usage per cell of their pastes for front-side and back side applications while improving the cells’ efficiency.
“Silver bullion prices have eased over the last nine months, as increased silver bullion production has resulted in an oversupply. Whether this is a permanent situation or not, Heraeus will continue in the direction of reducing the silver usage in cells”
.According to Andy London, Global Manager of Heraeus Photovoltaics, “Heraeus develops front-side and backside pastes that lower the silver content per cell. Front–side silver paste has become an increasing cost in the production of crystalline solar cells as silver bullion prices have escalated to historic highs. Heraeus addresses the need to reduce that cost by producing silver pastes that allow for up to 40% reduction in silver usage.”
Andy London states, “Heraeus SOL9600, our current new product for the front-side, prints finer lines thus reducing silver usage and increase efficiency due to less shading. Heraeus SOL205S, our current product for the back-side, is produced using 52% silver content, further reducing silver usage on the cell. Heraeus SOL315, our current product for passivated emitters has a silver content significantly less than standard pastes.”
“Silver bullion prices have eased over the last nine months, as increased silver bullion production has resulted in an oversupply. Whether this is a permanent situation or not, Heraeus will continue in the direction of reducing the silver usage in cells,” says Andy London.
