21. Development of Concentrating Photovoltaic-Thermal Solar Collectors
Sammanfattning : Fossil fuels have greatly improved human living standards and saved countless lives. However, today, their continued use threatens human survival, as CO2 levels rise at an unprecedented pace to levels never seen during human existenceon earth. LÄS MER
22. Advanced Nanostructured Transition Metal Oxide Semiconductors for Solar Energy Applications
Sammanfattning : Increasing energy consumption and its environmental impacts make it necessary to look for alternative energy sources. Solar energy as huge energy source that can cover the terms sustainability is considered as a favorable alternative. LÄS MER
23. Synthesis and Robotized Screening of Novel Perovskite Materials for Solar Cell Application
Sammanfattning : As of today, the energy consumption in the world is high and is essential in the development and growth of the modern-day society. The world energy consumption is projected to increase significantly over the next decades. LÄS MER
24. Band gap engineering in Cu2ZnGexSn1-xS4 thin film solar cells
Sammanfattning : Photovoltaics based on kesterite Cu2ZnSnS4 (CZTS) has attracted interest as a sustainable alternative to other thin film technologies due to their tunable material properties and earth-abundance. However, the efficiency is limited to 12. LÄS MER
25. Focused Ion Beam Preparation and Transmission Electron Microscopy of Materials for Energy Applications
Sammanfattning : Throughout this thesis, samples of various materials with applications in energy converting devices have been prepared by focused ion beam machining and investigated by transmission electron microscopy. Energy converting devices can be solar cells or light emitting diodes, which turn light into electricity or vice versa. LÄS MER
