21. Quantum photoelectrochemistry : Theoretical studies of organic adsorbates on metal oxides surfaces
Sammanfattning : Interactions between organic molecules and transition metal oxide surfaces have been investigated by means of quantum chemical calculations. The studies have been aimed at understanding electrode-adsorbate interactions in photoelectrochemical devices, such as dye-sensitized solar cells. LÄS MER
22. Light propagation in an anisotropically scattering medium
Sammanfattning : Scattering is the main phenomenon of light-matter interaction. In this thesis, we consider one specific case of light propagation in a material whose structure causes anisotropic optical scattering - transparent wood. LÄS MER
23. Characterisation of Organic Dyes for Solid State Dye-Sensitized Solar Cells
Sammanfattning : Energy from the sun can be converted to low cost electricity using dye-sensitized solar cells (DSCs). Dye molecules adsorbed to the surface of mesoporous TiO2 absorb light and inject electrons into the semiconductor. LÄS MER
24. Novel organic sensitizers and hole transport materials for efficient solid-state photovoltaic devices
Sammanfattning : State-of-art solid-state photovoltaic devices, such as solid-state dye sensitized solar cells (ssDSSCs) and perovskite solar cells have attracted significant attention due to their high efficiency and potential low-cost manufacture. However, there are still challenges that limit the application up-scaling.. LÄS MER
25. Liquid Redox Electrolytes for Dye-Sensitized Solar Cells
Sammanfattning : This thesis focuses on liquid redox electrolytes in dye-sensitized solar cells (DSCs). A liquid redox electrolyte, as one of the key constituents in DSCs, typically consists of a redox mediator, additives and a solvent. LÄS MER
