  1. 1. Stability of electron acceptor materials for organic solar cells : a work function study of C60/C70 derivatives and N2200

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Sebastian Ekhagen; [2019]
    Nyckelord :;

    Sammanfattning : Thin films of the fullerenes PC60BM and PC70BM and the non-fullerene N2200, three popular electron acceptor materials in organic photovoltaics, have been studied, using both the Kelvin probe method as well as ultraviolet photoelectron spectroscopy. With these methods the work function was measured, as well as the highest occupied molecular orbital (HOMO) onset. LÄS MER

  3. 2. Characterizing particulate carbon using dielectric property measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Madeleine Syk; Joakim Vollmer; [2018]
    Nyckelord :black carbon; elemental carbon; carbonaceous aerosols; soot; fullerene C60; multiwalled carbon nanotubes; mesoporous carbon; impedance; dielectric; snow melting; capacitance; waveguide;

    Sammanfattning : Interest in effects of carbonaceous particles in the atmosphere has recently taken an upswing due to knowledge of how these particles affect our environment. Carbonaceous aerosols are characterized by their dark color, giving them the ability to absorb both incoming and outgoing radiation of all wavelengths in the atmosphere. LÄS MER

  5. 4. DFT investigations of the donor-acceptor couple CuPc/C60

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Pamela Svensson; [2016]
    Nyckelord :DFT; donor; acceptor; couple; CuPc; C60; XPS; XES; NEXAFS; spectroscopy; organic; solar; cell; buckminsterfullerene; copper; phthalocyanine; blue;

    Sammanfattning : The donor-acceptor couple CuPc/C60 has been the subject of recent studies in organic solar cells due to its combined abilities in light absorption (CuPc) and charge transport (C60). By better understanding the electronic and geometric nature of the system it is possible to shed light on how the molecules act under different conditions. LÄS MER
