Two solar energy firms in China are collaborating to advance technology for higher efficiency solar cells. The solar photovoltaic arm of firm Dupont Solutions and Yingli Green Energy, one of the world’s largest vertically integrated photovoltaic manufacturers, are working together to develop module manufacturing processes and innovative component designs for solar cells.

Through technical collaboration, the two companies aim to accelerate the development and adoption of solar energy to address one of the world’s biggest challenges – sustainable energy generation.

Liansheng Miao, chairman and chief executive officer of Yingli Green Energy, said: “Technology innovation, especially through collaboration with leading materials suppliers such as DuPont, enables us to deliver high-quality, cost-competitive products. And is at the core of our ability to continually grow and lead in this industry, which will further underscore our commitment to providing the whole world with affordable green solar energy.”

Working together, Yingli Solar and DuPont have made significant advancements in raising solar cell efficiency, extending module lifetime and targeting lower overall photovoltaic system costs.

Yingli is integrating DuPont metallisation technology with an advanced cell diffusion process for greater efficiency increases, based on the Solamet PV17x technology platform.

Yingli and DuPont are also collaborating to customise metallisation materials for Yingli’s new Panda series modules, made with an advanced (N-type) cell design for superior efficiency of over 19 per cent based on current lab testing.

The two companies are also collaborating in fluoride films, such as DuPont Tedlar polyvinyl fluoride films adopted in Yingli’s new Panda modules, ensuring high performance power output for more than 25 years.

William F. Feehery, global business director, DuPont Photovoltaic Solutions, said: “Achieving the best possible performance and lowest total cost from photovoltaic technology is more critical than ever as solar energy is gaining competitive advantage verses non-renewable energy sources.

“Global collaboration helps to accelerate innovation, and most importantly, encourage faster and broader adoption of solar power, which is good for consumers and the environment. We are glad to collaborate with leading module makers like Yingli.”
