1. Buoy and Generator Interaction with Ocean Waves Studies of a Wave Energy Conversion System
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : On March 13th, 2006, the Division of Electricity at Uppsala University deployed its first wave energy converter, L1, in the ocean southwest of Lysekil. L1 consisted of a buoy at the surface, connected through a line to a linear generator on the seabed. READ MORE

2. Submerged Transmission in Wave Energy Converters Full Scale In-Situ Experimental Measurements
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : Different wave power technologies are in development around the world in different stages of prototype testing. So far only a few devices have been deployed offshore at full scale for extended periods of time. Little data is published about how these different devices perform. READ MORE

3. Microscopic Characterisation of Solar Cells An Electron Microscopy Study of Cu(In,Ga)Se2 and Cu2ZnSn(S,Se)4 Solar Cells
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : The sun provides us with a surplus of energy convertible to electricity using solar cells. This thesis focuses on solar cells based on chalcopyrite (CIGSe) as well as kesterite (CZTS(e)) absorber layers. These materials yield record efficiencies of 20.4 % and 11. READ MORE

4. Power transfer in the air gap of linear generators for wave power
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : An increased need for electric energy and share of renewable energy is important for a more sustainable future, to which wave power can contribute. Some concepts for wave power use linear generators, and the studies presented here focus on the power transfer and forces in the air gap of linear generators. READ MORE

5. System Perspectives on Hydro-Kinetic Energy Conversion
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : Free-flowing water currents such as tides and unregulated water courses could contribute to world electricity production given the emergence of robust technical solutions for extracting the energy. At Uppsala University, a concept for converting the energy in water currents to electricity using a vertical axis turbine with fixed blade-pitch and a direct-drive permanent magnet generator is studied.
