摘　　要：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.The effects of the cathode operation voltage, the absorption coefficient, the cartier 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.
