These Windows Can Generate Electricity And Provide Insulation


You probably won't find any windows anywhere that can do both. Not yet anyway.​

This could be about to change. Chinese scientists have invented a new material that can both block the sun and produce power. They predict that windows outfitted with this product—or even window curtains that have it—eventually could cut the average household's electric bills by half or more.

"We combine both material innovation and optical thin film design to achieve the goal of combining both solar electricity generation and heat insulation in one single film," said Hin-Lap (Angus) Yip, a professor of materials science and engineering at the South China University of Technology. "Our energy efficiency for the house is kind of double: power generation and power saving."
