Charge Transportation in Organic Materials

Although it has not yet been possible to fully analyse the temperature behaviour and, in particular, to determine the mobility from the device characteristics of this ideal OSC-device, we believe that such model devices, where structural defects such as domain boundaries and reorientation layers as well as contamination are largely absent will be very important for unravelling the physics governing charge transport in organic materials. 

The important topic of charge transport in organic materials is outside the scope of this chapter, and for that we refer the reader to excellent review papers and book chapters [7-11]. Suffice here to recall a few basic concepts that will help in dealing with the problem of interfaces.
