"Solar cell manufacturers can significantly reduce their cost per watt of solar energy by using high-performing materials that allow them to achieve higher cell efficiencies, higher production yields, and more efficient use of materials," said Robert Cockerill, Thin Film Photovoltaic marketing manager - DuPont Microcircuit Materials.

"We worked closely with leading thin film PV manufacturers as we developed Solamet PV412, because we share a common goal of enabling more cost-effective manufacturing of solar cells with improved efficiency and yield to help solar energy become more competitive with other forms of energy generation."

DuPont collaborated with Ascent Solar Technologies, Inc. (ASTI), a developer of state-of-the-art flexible thin-film solar modules, as it developed Solamet PV412.

"Innovative materials are critical to advancing our technology for thin film photovoltaics," said Prem Nath, senior vice president Production-Operations - Ascent Solar Technologies.

"ASTI is building a position as a leader in the production of lightweight flexible photovoltaics used for portable power and building integrated photovoltaic (BIPV) products. As our technology has evolved, the ability to work closely with our supplier DuPont in early stage testing as it adapted Solamet photovoltaic metallizations to other materials and manufacturing processes has been a big advantage."

DuPont Solamet PV412 photovoltaic metallization paste is designed for use on devices where a Transparent Conductive Oxide is utilized. It is ideal for use with Copper Indium Gallium Selenide (CIGS), Amorphous Silicon (a-Si) on flexible substrates, and Heterojunction with intrinsic thin layers (HIT) PV cells, and also suitable for any PV application where a low temperature curing conductor is required.

Key features include fine line printing down to 80um resolution, long screen residence time for robust printer operation, low contact resistance, low gridline resistance, high adhesion to indium tin oxide, and strong compatibility with most transparent conductive oxides.

DuPont expects to nearly triple its annual photovoltaic sales across all product platforms to more than $1 billion in 2012 based on strong fundamentals for long-term revenue growth in the photovoltaic solar energy market, combined with the company's ability to deliver new technologies to the industry.
