Chinese and US PV tech firms in $100m “key collaboration” to advance solar materials

Yingli Energy and DuPont sign expanded strategic agreement for the supply of solar pastes and film to boost solar cell power

The deal will see Yingli China purchase metallisation pastes and PV films from DuPont to help increase the power output of solar cells

Chinese and US PV technology firms have come together in a USD 100m "key collaboration" to spur on developments in solar materials. China's Yingli Energy and DuPont, which has global headquarters in US state Delaware, have signed the one year strategic agreement for the supply of advanced solar materials, including films and metallisation pastes, to boost solar cell power output.

The agreement includes the installation of a DuPont solar power plant in China, as well as co-marketing initiatives aimed at accelerating the "broader and faster adoption" of solar energy to address the world's growing energy needs.

The deal is an expansion of a supply agreement between the companies announced in February 2012. It follows similar deals DuPont has made with Chinese solar companies, such as Trina Solar.

Liansheng Miao, chairman and chief executive officer, Yingli Green Energy, said: "Materials are critical to help ensure our solar panels provide superior power output for their 25-year expected lifetime, or longer. The agreement we have signed with DuPont assures our supply of high-quality materials that have proven performance and our continued collaboration on further technological advances to optimise the efficiency and durability of our products."

Under the terms of the agreement, Yingli China will purchase materials including DuPont's Solamet photovoltaic metallisation pastes that help boost the power output of solar cells. The company will also purchase DuPont's Tedlar polyvinyl fluoride film, which has been proven to protect solar panels even in the harshest environmental conditions.
