  1. 26. Low Band-Gap Conjugated Polymers for Plastic Solar Cells

    Författare :Erik Per Perzon; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; low band-gap conjugated polymers; Plastic solar cells;

    Sammanfattning : Today, fossil fuels like coal, oil, and natural gas are used for more than 60% of the world's electricity production. These fuels have a very negative impact on the environment and many researchers agree that the earth's climate is changing as a consequence of fossil fuel emissions. LÄS MER

  3. 27. Electron tomography and optical modelling for organic solar cells

    Författare :Viktor Andersson; Olle Inganäs; Joachim Loos; Linköpings universitet; []
    Nyckelord :Organic solar cells; Electron tomography; Optical modelling;

    Sammanfattning : Organic solar cells using carbon based materials have the potential to deliver cheap solar electricity. The aim is to be able to produce solar cells with common printing techniques on flexible substrates, and as organic materials can be made soluble in various solvents, they are well adapted to such techniques.

  4. 28. 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

  5. 29. Recycling of CIGS solar cell waste materials

    Författare :Anna Gustafsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrometallurgy; Pyrometallurgy; CIGS; Recycling; Solar cells;

    Sammanfattning : The increased interest in solar power over the last few decades has led to a constant development of existing and new types of solar cells. One type of solar cell that is making advances on the global market is copper indium gallium diselenide (CIGS) thin film solar cells. LÄS MER

  7. 30. Liquid Redox Electrolytes for Dye-Sensitized Solar Cells

    Författare :Ze Yu; Lars Kloo; Md K Nazeeruddin; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dye-sensitized solar cells; electrolytes; ionic liquids; redox couples; additives;

    Sammanfattning : This thesis focuses on liquid redox electrolytes in dye-sensitized solar cells (DSCs). A liquid redox electrolyte, as one of the key constituents in DSCs, typically consists of a redox mediator, additives and a solvent. LÄS MER
