But the materials also show promise for a new generation of cheap, flexible, lightweight solar cells. And they show even more promise as soft, flexible bioelectronic interfaces to living tissue — “one of the emerging and very exciting applications of organic semiconductors,” says Carlos Silva, a physicist at Georgia Tech in Atlanta. These applications include drug delivery and biosensors.
