Physicists have discovered new properties in a material that could result in efficient and inexpensive plastic solar cells. The discovery reveals that excitons, or energy-carrying particles generated by photons, can travel on the order of a thousand times farther in organic semiconductors than scientists previously observed. This boosts scientists' hopes that organic solar cells may one day overtake silicon in cost and performance.
