21. Optical Efficiency of Low-Concentrating Solar Energy Systems with Parabolic Reflectors
Sammanfattning : Solar electricity is a promising energy technology for the future, and by using reflectors for concentrating solar radiation onto photovoltaic cells, the cost per produced kWh can be significantly reduced. The optical efficiency of a concentrating system determines the fraction of the incident energy that is transferred to the cells and depends on the optical properties of the system components.

22. Optical Design for Stationary Solar Concentrators
Sammanfattning : Solar electricity is one of the most promising technologies for our future electricity supply. By using concentrators, it is possible to reduce the cost of generating photovoltaic electricity. This thesis discusses how to design stationary low concentrating systems for photovoltaic or PV/Thermal applications. LÄS MER
23. The morphology of polyfluorene : fullerene blend films for photovoltaic applications
Sammanfattning : Polymer photovoltaic systems whose photoactive layer is a blend of a semiconducting polymer with a fullerene derivative in a bulk heterojunction configuration are amongst the most successful organic photovoltaic devices nowadays. The three-dimensional organization in these layers (the morphology) plays a crucial role in the performance of the devices. LÄS MER
24. Solar energy for a brighter life. A case study of rural electrification through solar photovoltaic technology in the Eastern Province, Zambia
Sammanfattning : Electricity is taken for granted in many parts of the world. In Sub-Saharan Africa, typically less than 5% of the rural population have access to this energy source. Even though electricity in itself does not lead to development, it can support a development process. LÄS MER
