Silicones in Solar Cell Modules Help Lower Cost of Solar Power, Dow Corning Expert Says

14-Apr-2010 - USA

Selecting the right material for solar cell modules can reduce labor, utility and equipment costs, improving module durability and efficiency according to Don Buchalski, senior marketing specialist for Dow Corning’s Solar Business, who participated in Greentech Media’s Solar Summit in Phoenix, Ariz. on March 31.

“Materials account for approximately 63 percent of costs associated with producing solar cell modules,” said Buchalski following his presentation in the ‘Optimizing Business Models for PV Manufacturing’ session. “Selecting a supplier who is committed to the industry, offers reliable supply and is a proven innovator is a key to long term success.”

As a case history, Buchalski discussed the breakthrough solar cell encapsulation technology commercialized in 2009 that improves performance and effectively lowers the total cost of ownership of solar power. Dow Corning® PV-6100 Encapsulant Series relies on the UV stability of the silicone molecule to deliver improved durability and increased efficiency for crystalline modules compared to incumbent organics.

“Silicon-based materials perform well for decades, even with exposure to extreme conditions,” Buchalski said. “They can also be engineered for fast cure speeds at lower temperature to bring benefits beyond the material to lower overall manufacturing cost.”
