DuPont Photovoltaic Solutions Highlights New Material Advances at Industry Leading Solar Expo

Innovations Push the Boundaries of Solar Panel Performance

SHANGHAI, April 27, 2015 - DuPont Photovoltaic Solutions (DuPont) is highlighting new advanced materials designed to improve the power output, reliability and return on investment (ROI) for solar energy systems during the SNEC Photovoltaic (PV) Power Expo, April 27 - 30, 2015, in Shanghai, China. The DuPont booth (W4-555) will feature two new DuPont Solamet photovoltaic metallization pastes for high-efficiency solar cells and collaborations with key customers. During 14 different leadership and technical forums, DuPont will share insights on the market, technology and the future of the solar energy industry.

"DuPont continues to deliver innovative materials that help make solar cells more efficient, and solar panels more powerful and profitable long term," said Chuck Xu, global business director, DuPont Photovoltaic Solutions. "Our newest Solamet technology advances are particularly exciting as they continue to break down barriers to higher panel power performance."

Featured attractions in the DuPont booth include:

· Two new DuPont Solamet photovoltaic metallization pastes for high-efficiency solar cells, including Solamet PV19x frontside silver pastes and Solamet PV76x pastes for advanced PERC solar cell architectures. By improving the efficiency with which a solar cell converts sunlight to electricity, Solamet pastes help boost the power output of solar panels.

· High-efficiency solar panels based on the latest advances in Solamet pastes, including Yingli PANDA, Solartech Sapphire, and Jinko Eagle panels, as well as panels from China Power Investment (CPI) and China Energy Conservation and Environmental Protection (CECEP), made using advanced materials from DuPont.

· DuPont Tedlar polyvinyl fluoride (PVF) film - the only backsheet material proven to protect solar panels in the field for more than 30 years even in extreme conditions.

· Panels from the extensive DuPont field testing program that demonstrate how materials selections can impact system performance and lifetime.

· Findings from the latest field research across China, the United States and Europe that indicate issues with current solar panel testing methods, and demonstrate the need for stronger standards to help ensure reliable performance over the lifetime of systems.
