Numerical study on the short-circuit current in single layer organic solar cells with Schottkey contacts

Abstract

The effects of the cathode operation voltage, the absorption coefficient, the carrier mobility, the temperature and the thickness of organic active layer on the short-circuit current density of single layer organic solar cells (OSCs) with Schottkey contacts are numerically studied. Quantitative dependences of the short-circuit current density on the respective parameters are obtained. The results show that a larger operation-voltage difference between the anode and the cathode, a higher carrier mobility as well as a thinner organic layer thickness are of great benefit to the increase of the short-circuit current density.
