Traditional solar cells use a brittle silicon backing, like computer chips. Jiang's organic solar cells rely upon a polymer that can be dissolved and printed onto flexible material.
"These materials have a lot more potential than traditional silicon," says Jiang. "They could be sprayed on any surface that is exposed to sunlight -- a uniform, a car, a house."
