Saflex® Photovoltaic
Focuses on Thin Film

Solutia Inc. in St. Louis announced that its new Saflex® Photovoltaic business is providing PVB interlayer and technical expertise in encapsulation technology to several companies that are producing the world’s largest thin-film solar modules.

“Saflex is committed to growing photovoltaic into a third major business segment, similar in size to our well-established architectural and automotive businesses,” says Luc De Temmerman, senior vice president of Solutia Inc. and president of Saflex. “By collaborating with leading equipment manufacturers, integrators, specifiers and module makers, Saflex will play a key role in shaping the future of this dynamic and rapidly growing market.”

“Currently Saflex is supplying large-scale module makers in Germany, Spain, and India, with expansion into additional world areas in the coming months,” says Jay Pyper, global market development director of the Saflex solar business. “These customers will be producing the world’s largest thin-film solar modules, using Saflex PVB interlayer as the encapsulant. Our global Saflex team will be actively engaged in supporting the startup and optimization of these new lines.” ❙❙➤ www.saflex.com

Nihon’s New Window
Can Power Your Cell Phone
Nihon Telecommunication System Inc. in Tokyo has introduced a window that the company says is able to generate up to 70 watts of electricity per square meter of glass.

According to an article in The Japan Times, the built-in photovoltaics provide enough electricity to keep a PC running (while the sun is out) or to recharge a mobile phone.

The cells reported to have a power generation efficiency of 7 to 8 percent.

However, the article reports that the window only provides power via a USB plug, which is what limits the range of products that can be powered or charged to small, hand-held devices.

While the amount of electricity may be small, the cost is not: $923 USD to as much as $2,769 USD per square meter of glass.

In addition, the relatively thick glass, measuring 10.5 mm, blocks as much as 90 percent of sunlight from entering a room. ❙❙➤ www.ntsk.jp/touya.html
