Momentive introduces new SilTRUST silicone encapsulant technology


Momentive Performance Materials, a provider of silicones and advanced materials, has launched its new SilTRUST silicone encapsulant technology.

SilTRUST silicone encapsulant materials, based on a combination of optical and mechanical properties, can be used to produce crystalline silicon photovoltaic (PV) modules with longer lifecycle use and better energy conversion efficiency, as well as manufacture crystalline silicon solar modules for terrestrial purposes.

"In tests, this encapsulant material outperformed traditional encapsulant materials in PV applications," Scholten added."

The encapsulant constitutes of a stress dissipating silicone matrix which surrounds and protects the fragile solar cells of the PV module in harsh outdoor environments while improving the light-to-electricity conversion yield.

Alex Scholten, Momentive Performance Materials eco-energy global programme leader, said SilTRUST silicone encapsulation of solar cells has been shown to improve the efficiency and durability of solar panels, as well as lower manufacturing costs.

"In tests, this encapsulant material outperformed traditional encapsulant materials in PV applications," Scholten added.

"With our project collaborators, we have also developed a lower temperature, cost-effective module manufacturing process to offer flexibility in equipment and raw materials use, as well as ease and speed in processing."

Momentive Performance Materials engineered materials technology leader Markus Putzer said developments in encapsulant formulations and processing technology will lead to good quality solar panels which are less expensive to make.

"At Momentive, we see this as a contribution towards making solar energy a competitive, reliable and sustainable source of energy," Putzer said.

Headquartered in the US, Momentive Performance Materials manufactures silicone, silicone-based derivatives, quartz, ceramics and other specialty materials for use in diverse industrial applications.
