Solar power via windows?

I’ve finally started a subscription to MIT’s Technology Review magazine. My first issue arrived last week, and I was all gaga over this totally cool (no pun intended) power providing window. I’m sure others won’t be as impressed as I am, but then again – I’m easily impressed.


The next building material to generate solar power may be windows. In a dye-sensitized solar cell, dye molecules attached to nanoscale titania particles are held between two panes of glass; the dye absorbs light and releases electrons, which are harvested by the ­titania. The basic concept was invented 15 years ago by Michaël ­Grätzel, chemistry professor at the École Polytechnique Fédérale de Lausanne in Switzerland. Now, the technology is in limited production by Konarka, a company based in ­Lowell, MA, and will soon be more widely available. “The normal configuration has glass on both sides and can be made to look like a colored glass,” Grätzel says. “This could be used as a power-producing window or skylights or building facades. The wall or window itself is photovoltaically active.” This could give a whole new meaning to the term “power windows.”

I can’t figure out yet how to put these to use, but I gotta get m3h some of them winders.
