  2. 1. Stability of Bulk-heterojunction blends for Solar Cell Applications

    Author : Camilla Lindqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanostructure; PCBM crystallisation; bulk-heterojunction; Polymer solar cells; stability;

    Abstract : Polymer solar cells are a promising alternative to more traditional silicon solar cells. This is mainly due to the good solubility of organic semiconductors, which makes it possible to produce large-scale and mechanically flexible devices with roll-to-roll processes. READ MORE

  4. 2. Morphology and material stability in polymer solar cells

    Author : Rickard Hansson; Ellen Moons; Andreas Opitz; Mats Fahlman; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polymer solar cell; photovoltaics; morphology; photo-degradation; conjugated polymer; fullerene; synchroton-based techniques; Physics; Fysik;

    Abstract : Polymer solar cells are promising in that they are inexpensive to produce, and due to their mechanical flexibility have the potential for use in applications not possible for more traditional types of solar cells. The performance of polymer solar cells depends strongly on the distribution of electron donor and acceptor material in the active layer. READ MORE

  5. 3. 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

  6. 4. Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

    Author : Daniel Hagberg; Licheng Sun; Elena Galoppini; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acceptor; chromophore; donor; dye sensitized solar cells; HOMO and LUMO energy level tuning; linker; organic dye.; Chemical engineering; Kemiteknik;

    Abstract :   This thesis deals with development and synthesis of organic chromophores for dye sensitized solar cells. The chromophores are divided into three components; donor, linker and acceptor. The development of efficient organic chromophores for dye sensitized solar cells starts off with one new organic chromophore, D5. READ MORE

  7. 5. Evolution and control of the three dimensional functional microstructure of Polymer:Fullerene photovoltaic blends

    Author : Olof Bäcke; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crosslinking; fullerene crystals; tomography; transmission electron mi- croscopy; organic solar cell; in situ; polymer:fullerene film; thermal degradation;

    Abstract : Polymer:fullerene bulk-heterojunction thin films show great promise for use as active layers in organic solar cells. However, their low thermal stability is a hindrance that complicates the manufacturing and influences the lifetime of devices. READ MORE
