To recall the basics, a brief review on semiconductor physics with emphasis on the p-n junction is given. We discuss the role of the electrochemical potential as driving for

In the second part, specific models for physical processes are discussed, which range from mobility and recombination models to the description of CT states, traps, interface bar

In particular we investigate the interplay between mobilities and different recombination mechanisms and their effect on the fill factor and the open-cir

Interplay Between Electrodes and Active Materials: The Open-Circuit Voltage and S-shaped , Curvesthe interface between a hole-transport layer and the donor is selected. This interface serves as a model system for a contact between active layer and electrode in general. Different values for the HOMO levels of both organic materials give rise to barriers for injection or extraction of charge carr

Consequently, it is desired to remove them based on the knowledge of their origin. In the previous chapter, barriers at electrodes have been discussed as poss
