Ching Tang and Steven van Slyke invented the first organic light emitting diode (OLED)in 1987 after they discovered that light can be emitted by passing current througha carbon-based material [TV87]. Since then organic molecules have been used additionally in organic field transistors (OFETs) [KTA03] and photovoltaic cells (OPVC)[YSF05]. Organic solar cells are very promising as they have many advantages compared to inorganic devices: 10 times thinner active layers are sufficient, the costs are much less and the production is easier. To compete with inorganic solar cells however the efficiency of the organic solar cells has to be increased by a factor of 2-3 [Kie07]. For further development and an increase of the efficiency of these devices, different materials have been studied as small organic molecules and polymers. This should lead to deeper knowledge of fundamental mechanisms at organic-metal and organic-organic interfaces, in order to find the material of choice. Many different homomolecular prototype systems of semiconducting molecules on metals have therefore been investigated extensively in the last decade [Tau07], [For97], [EBST04], [BLC+10], [SHK+09], [KSS+10], [DGS+07]. Studying the formation of the first layer is necessary as it is crucial for the growth of the subsequent layers [BCK05], in the end defining the properties of the organic device. [...]
