Ferro Electronic Material Systems, a supplier of materials for fabricating photovoltaic silicon solar cells, has expanded its product line with the introduction of five new products at the 24th European Photovoltaic Solar Energy Conference and Exhibition.
Products in this family, NS 33-510 and NS 33-520, yield greater power output, fire through silicon nitride anti-reflective coatings, and provide a broad processing window, the company says. They form excellent contact on 55-70 ohms/square high sheet resistivity emitters, and their rheology is suitable for high-aspect-ratio grid lines.
Ferro's AL 53-110 Series are lead- and cadmium-free aluminum conductors for the back surface of 180-220-nanometer thick silicon wafers. They exhibit less than 1.5-mm camber on 150 x 150-mm wafers at 180-nanometer thickness, enabling solar cell manufacturers to reduce silicon usage and costs.
PS 33-610 and PS 33-612 are cost-effective thrifted silver conductor pastes that provide high adhesion and excellent solderability when used with lead-free solders. Low interfacial resistance yields improved electrical performance, the company adds.
In addition, Ferro has begun production of solar aluminum paste at its expanded Suzhou, China, facility. The 16,500 square-meter plant has room for future expansion to manufacture products such as silver pastes, surface technology products, multilayer materials, electronic glass and precious metal powders. The Suzhou facility also houses an applications laboratory to support regional development.
