We model the electron photoemission from metal nanoparticles into in a Schottky diode. We show that plasmonic effects in the nanoparticles lead to a substantial enhancement in photoemission compared with devices with continuous metal films. Such structure can provide an effective mechanism for the generation of a photocurrentt in the infrared range below the semiconductor bandgap, resulting in the development of plasmonic photoemission enhanced solar cells.
