The Fraunhofer Institute for Solar Energy Systems (ISE) has found that by using the Rasirc Steamer efficiency in the production of back contact silicon solar cells reached 20.2%. Fraunhofer used the steamer system to provide ultrapure water vapor for its metal wrap through (MWT) and passivated emitter and rear cell (PERC) solar cell manufacturing processes.

“It has been a very productive and positive experience working with the engineers from Fraunhofer ISE,” said Jeffrey Spiegelman, president of Rasirc. “It is very exciting to be an important part in bringing MWT/PERC cells to mass production.”

Rasirc’s Steamer is said to eradicate volatiles, ionic pollutants and other impurities from steam generated from DI water so that the steam can be applied in critical solar cell manufacturing processes. Additionally, the company states that yield becomes higher because metals, hydrocarbons and particles are excluded from the non-porous membrane in order to provide steam with purity in the parts per trillion.
