Dissertation, Erstveröffentlichung
Kurzbeschreibung (Abstract)
This thesis contributes to the understanding and controlling of the surface properties of solution-processed nickel oxide (NiO) and generally helps to properly interpret photoelectron spectra of NiO-based samples. The metal oxide semiconductor NiO possesses excellent charge selective properties and is often used in hole transport layers in optoelectronic devices. However, controlling the properties of NiO is extremely difficult, especially when it is solution-processed. In this thesis, the chemical composition and electronic properties of solution-processed NiO are analyzed as a function of the manufacturing parameters and surface modifications in form of oxygen plasma treatment and surface functionalization with self-assembled monolayers. The spectroscopic data obtained are correlated with the performance of corresponding NiO-based organic solar cells and conclusions on interface engineering are derived. The findings allow for an optimized application of solution-processed NiO layers in optoelectronic components.
