Jonathan Kesh: Researchers Design Solar Cells That Charge Phones With Ambient Light

When people think of solar panels, they usually think of the bulky rectangles made from silicon solar cells that you can attach to a household roof. They don't usually think of a neat design that you could print onto your backpack or t-shirt, which you could then hook up to your phone whenever you need to charge it.

And that's because solar-powered decals are only just starting to come around, with French solar energy company Dracula Technologies working on a new type of cheap, inkjet-printable solar cell that comes in a variety of shapes and colors.

More significantly, this type of plastic solar cell can absorb more than direct sunlight, with the ability to draw power from simple ambient light and artificial light from indoors.
