21. Shining Light on Molecules : Electron Transfer Processes in Model Systems for Solar Energy Conversion Investigated by Transient Absorption Spectroscopy
Sammanfattning : In the recent years, solar energy conversion has attracted a huge research interest due to the potential application for limiting the greenhouse effect. In many solar cells and solar fuel cells, understanding of charge transfer (CT) and recombination is important for future improvement of the overall efficiency. LÄS MER
Sammanfattning : Luminescence from the trivalent lanthanides is used for detection in biological systems. Lanthanide luminescence is usually sensitized by a light-harvesting organic chromophore (’antenna’). An ideal emitter has an antenna that efficiently transfers energy to the lanthanide, and a ligand that shields the metal from quenching solvent molecules. LÄS MER
Sammanfattning : This thesis is based on eight articles all related to the characteristics of the cooling system and plate evaporator of a household refrigerator. Through these articles, knowledge is provided that can be used to increase the operational efficiency in household refrigeration. LÄS MER
Sammanfattning : This thesis reports a state-of-the-art theoretical study of photophysical properties of organic charge-transfer aromatic molecules. These molecules are building blocks of molecular functional materials used in modern photonics technology and play essential roles in chemistry and biology in general. LÄS MER
25. Photoinduced Processes in Molecular-Inorganic Materials - Design Strategies for Control of Photophysical and Photochemical Processes
Sammanfattning : Sunlight is the most abundant renewable energy resource on Earth and has the potential to provide our society with clean energy. Despite this abundancy, solar energy corresponds to only a minority of the global energy production. Two major reasons for this are the limited efficiencies of solar cells and the difficulty of storing solar energy. LÄS MER
