Theory of Schottky barrier heights of amorphous MIS solar cells

[[abstract]]The Schottky barrier height φm of amorphous MIS solar cells depends greatly on the density of surface states Ds, and on the density of localized states near the Fermi level. At low density of gap states, the φm is maximum for Ds being around 1018 m−2 eV−1. With an illumination of light, the barrier height decreases as the collection of minority carriers near the interface increases.[[fileno]]2010122010026[[department]]物理
