Ferro Introduces Silver Conductor Pastes For Solar Cells


Ferro Electronic Materials, a supplier of materials for fabricating photovoltaic silicon solar cells, has developed the PS 213X Series, a new family of rear silver conductor pastes. According to the company, the new products offer up to 70% savings in silver compared to current pastes yielding a 10-micron fired busbar thickness.

Ferro's 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 mm per second, Ferro says.

The pastes are compatible with the company's back-surface aluminum pastes and can be co-fired in a wide processing window. The silver pastes are RoHS- and REACH-compliant and are free of lead, cadmium and phthalates, the company adds.
