  1. 6. In Light of Ionic Materials : A short exploration of ionic materials for light-related applications

    Författare :Brando Adranno; Anja-Verena Mudring; Annegret Stark; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ionic materials; ionic liquids; mesophases; light-emission; electrochemical applications; materialkemi; Materials Chemistry;

    Sammanfattning : Ionic liquids (ILs) have been one of the most attractive classes of materials of the last decades. The reason behind this is their peculiar set of properties, which enable their possible application in several research fields. ILs are salts that exhibit a very low melting point, which has been arbitrarily defined to be below 100 °C. LÄS MER

  3. 7. Stark Spectroscopy, Lifetimes and Coherence Effects in Diatomic Molecular Systems

  4. 8. Exploring Electronic Processes at the Mesoporous TiO2/Dye/Electrolyte Interface

    Författare :Wenxing Yang; Boschloo Gerrit; Hagfeldt Anders; Johansson Erik; Gerald Meyer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dye-sensitized solar cells; dye regeneration; Stark effect; the local electric field; cationic effect;

    Sammanfattning : Dye sensitized solar cells (DSSCs) are an attractive way to convert light into electricity. Its development requires a detailed understanding and kinetic optimization of various electronic processes, especially those occurring at the mesoporous TiO2/dye/electrolyte interface. LÄS MER

  5. 9. Quantum-Confined Stark Effect in Artificially Made Quantum Well Structures

    Författare :Weiquan Chen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The objective of the work presented in this thesis is to study the quantum-confined Stark effect in differently shaped quantum well structures. This effect has shown great interest and significant applications in optoelectronic devices. Most of the studies and applications have focused on square quantum wells. LÄS MER

  7. 10. 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
