A printable, flexible, organic solar cell
Unlike the solar cells you're used to seeing, organic photovoltaics are made of compounds that are dissolved in ink and can be printed and molded using simple techniques. The result is a low-weight, flexible, semi-transparent film that turns the energy of the sun into electricity. Hannah Bürckstümmer shows us how they're made -- and how they could change the way we power the world.
