摘要：
The electron transport and electrical properties in a methanofullerene PCBM are investigated. It is demonstrated that the temperature dependent and thickness dependent current density versus voltage characteristics of PCBM devices can be accurately described by using the improved mobility model. In addition, the width of the Gaussian density of states of PCBM is significantly smaller than the values usually reported for conjugated polymers. Furthermore, it is shown that the variation of voltage with boundary carrier density is dependent on the current density. Both the maximum of carder density and the minimum of electric field appear near the interface of devices.
