The agreement was signed to accelerate the adoption of solar energy and reduce the dependence on fossil fuels.

Under the terms of the agreement, Yingli will purchase photovoltaic materials including DuPont Solamet photovoltaic metallization pastes used in solar modules.

It also includes protective backsheet for solar modules made with DuPont Tedlar polyvinyl fluoride film.

The photovoltaic materials 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.

Yingli China is a wholly owned subsidiary of photovoltaic manufacturer, Yingli Green Energy Holding Company (Yingli).
