Amid a heated photovoltaic market, DuPont plans expanded production

In a sure sign of the growing demand for photovoltaic technology in the U.S. market, DuPont announced plans to expand its existing manufacturing plant in Fayetteville, North Carolina.

The plant produces the Tedlar product, a film used to back solar panels for stability and to increase efficiency. DuPont says demand for the film is increasing 30 percent a year. Many manufacturers and installers of photovoltaics have reported supply shortages in 2006, especially in light of a temporary scarcity of silicon for use in solar cells.

DuPont does not manufacture photovoltaic modules, but the company is the leading supplier of eight products that go into conventional crystalline silicon photovoltaic modules. The company’s clients include General Electric, Sharp, BP Solar, and Kyocera Solar.

“DuPont and Tedlar have played key roles in the solar energy industry,” says Cynthia Green, vice president and general manager at DuPont. “This expansion will allow us to better supply customers in several global market segments as we focus more of our science and innovation on improving the life cycle of solar cells and reducing the cost per watt of electricity to consumers and building owners.”

The company is investing more than $50 million in the North Carolina facility, as well as an additional $50 million in other facilities in North America. In addition to films, the company manufactures resins for encapsulants, encapsulant interlayers, and conductive pastes for photovoltaics (refer to the diagram).
