  3. 12. Conjugated polymers with functional side chains for photovoltaics

    Författare :Kim Bini; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; side chain engineering; polymer solar cells; green solvent solubility; transmission electron microscopy; conjugated polymers;

    Sammanfattning : Polymer solar cells are quickly approaching viability as a large scale electrical power source. To increase their stability and processability in green solvents, we want to modify their solubilizing side chains with different functionalities. LÄS MER

  4. 13. Evolution and control of the three dimensional functional microstructure of Polymer:Fullerene photovoltaic blends

    Författare :Olof Bäcke; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 14. Light Trapping and Alternative Electrodes for Organic Photovoltaic Devices

    Författare :Kristofer Tvingstedt; Olle Inganäs; Peter Peumans; Linköpings universitet; []
    Nyckelord :Light trapping; Organic solar cells; Tandem cells; Polymer solar cells; Plastsolceller; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Organic materials, such as conjugated polymers, have emerged as a promising alternative for the production of inexpensive and flexible photovoltaic cells. As conjugated polymers are soluble, liquid based printing techniques enable production on large scale to a price much lower than that for inorganic based solar cells. LÄS MER

  7. 15. Organic Hole-Transport Materials for Perovskite Solar Cells
