Harnessing solar power, on a small scale

No thicker than a piece of paper – because it practically is a piece of paper – a solar panel created by an MIT researcher can be shoved into a pocket or made into a paper airplane, and it will still create energy when exposed to sunlight.

The trick is in the way it is made. The panel is printed like ink onto a sheet of paper. Even folded up like a letter, it retains its ability to convert light to electricity.
