Application of Bässler′s Energy and Position Disorder Model and Hoping Model in Hole Transport Material

Article Preview

Abstract:

The Bässler’s energy and position disorder model is used to study the relationship between molecular structure of hole-transport materials and performance of the photoreceptor. The result shows that dipolar moments of hole-transport materials (HTM) are inverse proportion to the half decay exposures (E1/2) of the Organic photoreceptors (OPC) which closely related with the hole-mobility of hole-transport layer. In this article Marcus hopping theory and DFT method are also used to calculate the hole-mobility of four hole-transport materials (HTM). The compare of the half decay exposures of OPCs used these material as hole-transport layer and hole mobility, dipolar moments of these molecules show that the E1/2 increases with decrease of hole mobility and dipolar moment.
