Abstract

In this article, we present a theoretical calculation of the charge carrier mobility in two different dendrimeric melt systems (dendritic phenylazomethine with a triphenyl amine core and dendritic carbazole with cyclic phenylazomethine as the core), which have recently been reported(1) to increase the efficiency of dye-sensitized solar cells by interface modification. Our mobility calculation, which is a combination of molecular dynamics simulation, first-principles calculation, and kinetic Monte Carlo simulation, leads to mobilities that are in quantitative agreement with available experimental data. We also show how the mobility depends on dendrimer generation. Furthermore, we examine the variation of mobility with an external electric field and external reorganization energy. Physical mechanisms behind the observed electric field and generation dependencies of mobility are also explored.
