Following-on from an RD&E collaboration between DuPont Photovoltaic Solutions and Yingli Green Energy in January 2011, the companies have signed a new US$100 million strategic agreement, that will see Yingli Green purchase DuPont’s Solamet metallization pastes and Tedlar polyvinyl fluoride backsheet for its solar modules. The agreement is designed to extend DuPont and Yingli's commercial relationships and material supply availability.
“At Yingli, we have a long-standing commitment to global social responsibility to make solar energy an affordable option for everyone,” said Liansheng Miao, chairman and chief executive officer, Yingli. “The agreement we have signed with DuPont assures our supply of critical, high-quality materials and our continued collaboration on further technological advances to optimize the performance of our solar modules, which illustrates our mission to be a cost leader and provide the best product to customers at the same time.”
“This agreement expands a current commercial relationship between DuPont and Yingli into a more strategic relationship with long-term benefit to both companies, and to end users of solar energy,” said David B. Miller, president, DuPont Electronics & Communications. “Materials are key to solar module performance, and DuPont continues to advance the science behind them. They help increase efficiency, extend the lifetime of modules, and, ultimately, help reduce overall system costs to make solar increasingly more competitive with other forms of energy generation.”
At the beginning of February 2012, DuPont also entered into a strategic agreement with Suntech, which specifically focused on technology advancements, supply chain optimization and cost reduction in relation to DuPont’s Tedlar polyvinyl fluoride film supply.
