Two-step photon up-conversion solar cells

Harvesting incident photons with energy below the bandgap may lead to highly efficient solar cells. By introducing InAs quantum dots at the hetero-interface, Asahiet al. achieve efficient two step photon up-conversion resulting in additional photocurrent and very high external quantum efficiency.
