Solar hydrogen generation: Exceeding 100% efficiency

Nature Energy volume 2, Article number: 17072 (2017) | Download Citation

Multiple exciton generation, in which two electron–hole pairs are generated from the absorption of one high-energy photon, has been demonstrated to improve efficiency in quantum-dot-based solar cells. Now, a photoelectrochemical system using PbS quantum dots is shown to drive hydrogen evolution with external quantum efficiency over 100%.
