Greentech Lead America: Ferro Electronic Materials, a
supplier of materials for fabricating photovoltaic silicon solar cells, will
launch new rear silver conductor pastes.
At SNEC 2012 PV Power Expo, being held in Shanghai,
China, May 16-18, the company will showcase new products that offer up to 70
percent savings in silver compared to current pastes yielding a 10-micron fired
Ferro claims that its new pastes offer savings to cell
manufacturers via reduced precious metal content and reduced paste laydown.
The products have pure silver metallurgy and enable fast
printing at speeds of more than 200 millimeters per second.
Moreover, they are compatible with the Company’s back
surface aluminum pastes and can be co-fired in a wide processing window. The
pastes provide robust soldering behavior with excellent adhesion to silicon
wafers. PS 213X Series silver pastes are RoHS- and REACH-compliant and are free
of lead, cadmium and phthalates.
“These new products lower the cost of ownership to
make solar energy more cost-competitive by reducing both precious metal content
and paste laydown. PS 213X pastes provide the same mechanical performance as current
pastes yielding a 10-micron fired busbar thickness at significantly lower
cost,” said Todd Williams, business manager for Ferro Electronic
Ferro Corporation has approximately 5,100 employees
globally and reported 2011 sales of $2.2 billion.
