  1. 1. Characterisation of Organic Dyes for Solid State Dye-Sensitized Solar Cells

    Författare :Ute Cappel; Anders Hagfeldt; Gerrit Boschloo; Udo Bach; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; energy alignment; hole conductor; injection; interface; perylene; photo-induced absorption; regeneration; spectroelectrochemistry; spiro-MeOTAD; Stark effect; titanium dioxide; Physical chemistry; Fysikalisk kemi; Physical Chemistry; Fysikalisk kemi;

    Sammanfattning : Energy from the sun can be converted to low cost electricity using dye-sensitized solar cells (DSCs). Dye molecules adsorbed to the surface of mesoporous TiO2 absorb light and inject electrons into the semiconductor. LÄS MER

  3. 2. Characterization of dye-sensitized solar cells : Components for environmentally friendly photovoltaics

    Författare :Hanna Ellis; Anders Hagfeldt; Gerrit Boschloo; Erik Johansson; Maria Hahlin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solar cells; dye-sensitized solar cells; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Sammanfattning : As fossil fuels, the major source of energy used today, create the greenhouse gas carbon dioxide which causes global warming, alternative energy sources are necessary in the future. There is a need for different types of renewable energy sources such as hydropower, windpower, wave- power and photovoltaics since different parts of the world have different possibilities. LÄS MER

  4. 3. Developing Environmentally Friendly Dye-sensitized Solar Cells

    Författare :Hanna Ellis; Gerrit Boschloo; Anders Hagfeldt; Erik Johansson; Aldo di Carlo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dye-sensitized solar cells; dye; cobalt; triphenylamine; titanium dioxide; aqueous; PEDOT; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Sammanfattning : Due to climate change and its effects, alternative renewable energy sources are needed in the future human society. In the work of this thesis, the Dye-sensitized Solar Cell (DSC) has been investigated and characterized. LÄS MER

  5. 4. Alternative Redox Couples for Dye-Sensitized Solar Cells

    Författare :Sandra Feldt; Anders Hagfeldt; Gerrit Boschloo; Petra Cameron; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; redox mediator; triphenylamine; cobalt; ferrocene; titanium dioxide; regeneration; recombination; Physical Chemistry; Fysikalisk kemi;

    Sammanfattning : Dye-sensitized solar cells (DSCs) convert sunlight to electricity at a low cost. In the DSC, a dye anchored to a mesoporous TiO2 semiconductor is responsible for capturing the sunlight. LÄS MER

  7. 5. Interactions in Dye-sensitized Solar Cells

    Författare :Helena Greijer Agrell; Anders Hagfeldt; Gerrit Boschloo; Laurence Peter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; solar cells; photovoltaics; dye-sensitized; mesoporous; nanostructured; Raman scattering; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The interactions between the molecular constituents in dye-sensitized solar cells were studied with UV-VIS and IR spectroscopy, Raman scattering, conductivity and electron accumulation measurements.From stability studies of the dye, bis(tetrabutylammonium)cis-bis(thiocyanato) bis(2,2’-bipyridine-4-carboxylic acid, 4’-carboxylate) ruthenium(II), in the complete solar cell, the thiocyanate ion ligand was found to be lost from the dye.
