1. 6. III-V Nanowire Solar Cells: Growth and Characterization

   Författare :Gaute Otnes; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanowire; Solar cell; Photovoltaic; Metal organic vapor phase epitaxy; Nanoimprint lithography; Electron beam induced current; Current-voltage characteristics; Doping; Fysicumarkivet A:2018:Otnes;

   Sammanfattning : To mitigate dangerous climate change, a transition to a new and sustainable energy system is needed. In this system, solar energy will need to be a key player. Prices of electricity made from solar cells have declined rapidly over the recent decades, making solar energy competitive in more markets. LÄS MER

   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

4. 8. Study into the Potential and Feasibility of a Standalone Solar-Wind Hybrid Electric Energy Supply System

   Författare :Getachew Bekele; Björn Palm; Philip Eames; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind Speed; Sunshine Duration; Solar Radiation; Feasibility Study; Standalone System; Solar-Wind Hybrid; Thermal energy engineering; Termisk energiteknik;

   Sammanfattning : The tendency to use renewable energy resources has grown continuouslyover the past few decades, be it due to fear over warnings of globalwarming or because of the depletion and short life of fossil fuels or evenas a result of the interest which has developed among researchers doingscientific research into it. This work can be considered as joining any ofthese groups with an objective of giving electric light to the poorpopulation living in one of the poorest nations in the world. LÄS MER

5. 9. Large Scale Solar Power Integration in Distribution Grids : PV Modelling, Voltage Support and Aggregation Studies

   Författare :Afshin Samadi; Lennart Söder; Olof Samuelsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic systems; PV system modelling; reactive power control; droop control; voltage sensitivity analysis; German Grid Codes; relative gain array RGA ; singular value decomposition SVD ; load modeling; system identification; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Long term supporting schemes for photovoltaic (PV) system installation have led to accommodating large numbers of PV systems within load pockets in distribution grids. High penetrations of PV systems can cause new technical challenges, such as voltage rise due to reverse power flow during light load and high PV generation conditions. LÄS MER

7. 10. Solar energy for a brighter life. A case study of rural electrification through solar photovoltaic technology in the Eastern Province, Zambia

   Författare :Mathias Gustavsson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rural development; rural electrification; distributed generation; photovoltaic technology; solar home system; energy services; Zambia; Sub Saharan Africa;

   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
