Abstract
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 variatio n of
voltage with boundary carrier density is dependent on the current density. Both the maximum of carrier density and the
minimum of electric field appear near the interface of devices..
