Ferro Electronic Materials, a supplier of materials for fabricating photovoltaic silicon solar cells, has introduced two new rear silver conductor pastes: PS 2130 and PS 2131.
According to the company, the two new products reduce the cost per watt while maintaining the same adhesion, solderability and field reliability as current commercial products. The pastes have pure silver metallurgy and enable fast printing at speeds of more than 200 millimeters per second. They are compatible with the company's back surface aluminum pastes and can be co-fired in a wide processing window.
PS 2130 and PS 2131 silver pastes are RoHS- and REACH-compliant and are
free of lead, cadmium and phthalates, the company adds.
