DuPont™ Tedlar® PVF films have been an essential component of photovoltaic backsheets for more than 25 years.


DuPont celebrated the completion of a $295 million expansion that has more than doubled production capacity for DuPont™ Tedlar® polyvinyl fluoride (PVF) film, the essential component of photovoltaic backsheets.  The expansion underscores the company’s commitment to help reduce global dependence on fossil fuels by providing materials and technologies designed to increase the adoption of solar energy.

“DuPont has recently signed supply contracts with several leading solar panel manufacturers, and with more customers qualifying and certifying Tedlar® every day, we anticipate even greater future demand,” said Dave Miller, president, DuPont Electronics & Communications.  “We continue to innovate with Tedlar® and other key materials to improve the efficiency and lifetime of solar modules as a means of bringing down overall system costs, to spur further adoption of solar energy and help reduce our dependence on fossil fuels.”

Yingli Green Energy recently signed a $100 million strategic agreement with DuPont to purchase photovoltaic materials, including protective backsheet for solar modules made with DuPont™ Tedlar® polyvinyl fluoride film.  Several other leading solar companies have announced collaborations with DuPont for photovoltaic materials aimed at accelerating the adoption of solar energy.  These include Trina Solar, China Sunergy/China Electric Equipment Group (CEEG), and Suntech Power Holdings Co., Ltd., the world’s largest producer of solar panels.

“DuPont™ Tedlar® is synonymous with safety and durability, so as a leading photovoltaic module supplier, we are excited by the prospect of our expanded, long-term partnership,” said Dengyuan Song, chief technology officer, Yingli Green Energy.
“Reliability is critical to quality for Suntech, so we depend on materials like backsheet based on Tedlar® films to differentiate and protect our brand as they help ensure our modules last 25-plus years in the field,” said Neal Holmlund, vice president of Operations and Supply Chain, Suntech America.

DuPont™ Tedlar® PVF films enable solar modules to achieve long-life performance, providing a long-term sustainable energy source for the marketplace.  This results in improved economic returns for investments in solar energy projects and therefore a lower cost of solar electricity to consumers.  Tedlar® films also are used in key applications for aerospace and other industrial applications because they are essential for long-term surface protection.

The expansion of Tedlar® film production at the Circleville facility resulted in the creation of more than 70 new DuPont jobs and about 30 additional contract positions.
