Researchers unleash graphene 'tiger' for more efficient optoelectronics
In traditional light-harvesting methods, energy from one photon only excites one electron or none depending on the absorber's energy gap. The remaining energy is lost as heat. But a new article describe one promising approach to coax photons into stimulating multiple electrons. Their method exploits some surprising quantum-level interactions to give one photon multiple potential electron partners.
