New Solar cells can use windows

business Updated: Jul 23, 2012 20:22 IST

Researchers have fashioned a new transparent solar cell that will not only permit windows at homes to generate power but also enable people to see outside.

The University of California Los Angeles team reported a new kind of polymer solar cell (PSC) that produces energy by absorbing mainly infrared light, not visible light, making the cells nearly 70% transparent.

They made the PSC from a photoactive plastic that converts infrared light into an electrical current. These polymer solar cells have attracted great attention due to their advantages over competing solar cell technologies, the Journal of the American Chemical Society reported.
