  2. 1. Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

    Author : Daniel Hagberg; Licheng Sun; Olof Ramström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic Chromophores; Dye Sensitized Solar Cells; Organic chemistry; Organisk kemi;

    Abstract : This thesis is divided into four parts with organic chromophores for dye sensitized solar cells as the common feature and an introduction with general concepts of the dye sensitized solar cells. The first part of the thesis describes the development of an efficient organic chromophore for dye sensitized solar cells. READ MORE

  4. 2. Multi-functional Chromophores

    Author : Fredrik Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : As the push towards green energy become stronger, more efficient systems needs to be developed to compete with fossil fuel based systems. In modern Grätzel solar cells, most of the energy losses are inherited from the choice of chromophore and metal oxide surface. READ MORE

  7. 5. Photoswitchable Peptidomimetics : Synthesis and Photomodulation of Functional Peptides

    Author : Miranda Varedian; Adolf Gogoll; Morten Grøtli; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; β-hairpin; peptidomimetics; stilbene; thioaurone; photochemistry; Organic chemistry; Organisk kemi;

    Abstract : The secondary structure of peptides is of pivotal importance for their biological function. The introduction of photoswitchable moieties into the backbones of peptides provides a unique way of regulating their conformation using an external stimulus, i.e., light. READ MORE
