Abstract

In this paper, we present an improved mobility model for charge transport in organic semiconductors by inserting the field dependent effective temperature instead of the real temperature into the temperature dependence of the mobility. The consistent descriptions with equal quality for the temperature and composition dependent current density-voltage characteristics of the hole-only devices based on TQ1:PC71BM:IC60BA ternary blends can be obtained by using the extended Gaussian disorder model (EGDM) and our improved model, respectively. However, the extracted values of average intersite distance from the two models are quite different. The values of from our improved model are very close to the typical value of organic semiconductors, and are obviously smaller than that from the EGDM, indicating that our improved model can provide a more appropriate description of the electric field and temperature dependence of the mobility than the EGDM..
