Two electrons from one photon

Nature Chemistry volume 2, pages 608609 (2010) | Download Citation

The absorption of a single photon can cause the excitation of more than one electron, but the mechanism of this 'multi-exciton generation' process is elusive. Now, calculations on pentacene show that geometrical distortions and intermediate excited states assist in producing two excited electrons from one photon.
