16. Towards Mixed Molecular Layers for Dye-Sensitized Solar Cells : A Photoelectron Spectroscopy Study
Sammanfattning : The increasing demand for renewable energy has led to substantial research on different solar cell technologies. The dye-sensitized solar cell (DSC) is a technology utilizing dye molecules for light absorption. LÄS MER
17. Techniques and Application of Electron Spectroscopy Based on Novel X-ray Sources
Sammanfattning : The curiosity of researchers to find novel characteristics and properties of matter constantly pushes for the development of instrumentation based on X-radiation. I present in this thesis techniques for electron spectroscopy based on developments of X-ray sources both in time structure and energy. LÄS MER
18. Electronic Properties of Metal Oxide Films Studied by Core Level Spectroscopy
Sammanfattning : In this dissertation core level electron spectroscopy has been employed to study various aspects of metal oxide films grown under ultra-high vacuum conditions. Studies on in situ ion insertion of lithium into thin TiO2 systems were performed. LÄS MER
19. The life and death of perovskites : Interfacial function and degradation of lead halide perovskites studied by photoelectron spectroscopy
Sammanfattning : Lead halide perovskite solar cells are a promising new technology which could soon see widespread commercial application but is partly held back by poor long-term stability. In this thesis, photoelectron spectroscopy (PES) is used to study the dynamical processes at the surface or interfaces of lead halide perovskite materials. LÄS MER
