Solar cells that convert windows into energy producers

Washington: 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 percent 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.
"These results open the potential for visibly transparent polymer
solar cells as add-on components of portable electronics, smart
windows and building-integrated photovoltaics and in other
applications," said study leader Yang Yang, a professor of
materials science and engineering at UCLA, according to a
university statement.
Yang added that there has been intense world-wide interest in
so-called polymer solar cells. "Our new PSCs are made from
plastic-like materials and are light weight and flexible," he
said. "More importantly, they can be produced in high volume at
low cost."

Believed to be built by Bibi Akbarabadi, one of the wives of then Mughal Emperor
Shah Jahan, the mosque is considered the twin of Fatehpuri Masjid
in Chandni Chowk. It is associated with the freedom movement of
1857 during which it was destroyed by the British.
Construction work was in progress after the discovery and
thousands of Muslim had offered Friday prayers on July 20,
2012. The Delhi High Court however handed over it to
archaeologists very next day. |
