Take a look: transparent solar panels
Imagine if instead of looking out your window to see your solar-panel array, your windows were your solar panel array? Sphelar solar cells can be built into windows, whether they're flat or curved. Instead of chasing the sun, they'll capture the sun from all angles.
Sphelar solar cells, from the Kyosemi Corporation, debuted at the PV Expo 2010 in Tokyo. They are solidified drops of silicon, 1.8mm across, that are embedded into glass of any shape. Potentially, the technology could be integrated into a decorative dome on top of a building, glass bricks, or just an ordinary office or home window. Because they're round drops, they'll pick up the sunlight at all times of day.
Although the Sphelar cells are clear, once they're embedded into glass, the window isn't completely clear, so this wouldn't make an ideal car window. However, it could be the newest twist on tinted glass for homes and offices.
Just think if all those shiny glass skyscrapers gracing most city skylines were actually generating their own power?
