  1. 6. Molecular Interaction of Thin Film Photosensitive Organic Dyes on TiO2 Surfaces

    Författare :Shun Yu; Mats Göthelid; Chassé Thomas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoelectron spectroscopy; X-ray absorption spectroscopy; organic semiconductor; oxides; adsorption; dye sensitization; electronic structure; charge transfer;

    Sammanfattning : The photosensitive molecule adsorption on titanium dioxide (TiO2) forms the so-called “dye sensitized TiO2” system, a typical organic/oxide heterojunction, which is of great interest in catalysis and energy applications, e.g. dye-sensitized solar cell (DSSC). Traditionally, the transition metal complex dyes are the focus of the study. LÄS MER

  3. 7. Electrolyte-Based Dynamics: Fundamental Studies for Stable Liquid Dye-Sensitized Solar Cells

    Författare :Jiajia Gao; Lars Kloo; Elizabeth Gibson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitized solar cells; Stability; Electrolyte; Cobalt redox couples; Additives; Kemi; Chemistry;

    Sammanfattning : The long-term outdoor durability of dye-sensitized solar cells (DSSCs) is still a challenging issue for the large-scale commercial application of this promising photovoltaic technique. In order to study the degradation mechanism of DSSCs, ageing tests under selected accelerating conditions were carried out. LÄS MER

  4. 8. Towards Harnessing Solar Energy with Iron N-Heterocyclic Carbene Complexes

    Författare :Olga Gordivska; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Negative impact of human activity-related emission of greenhouse gases on Earth's ecosphere has been known for decades, but has recently come into spotlight with unprecedented intensity. This is due to increasingly clear understanding that the global warming could soon spiral out of control. LÄS MER

  5. 9. Nanoparticle plasmon influence on the charge carrier generation in solar cells

    Författare :Carl Hägglund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; solar cells; finite element method; nanoparticle plasmons; photovoltaics; nanofabrication; Si; dye sensitized solar cells; localized surface plasmon resonances;

    Sammanfattning : Global warming is a potential threat to life on earth and to human society. It is by much evidence linked to the extensive use of fossil fuels in our present energy system. Replacing the fossil fuels by alternative sources of energy poses a tremendous challenge for mankind, but is not at all undoable. LÄS MER

  7. 10. Molecular Engineering of D-π-A Dyes for Dye-Sensitized Solar Cells

    Författare :Erik Gabrielsson; Licheng Sun; Peter Bäuerle; KTH; []
