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

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Sebastian Ekhagen; [2019]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. Development of synthetic methodology for non-symmetric fullerene dimers

    University essay from Uppsala universitet/Institutionen för kemi - BMC

    Author : Fredrik Barnå; [2019]
    Keywords : fullerene; dumbbell; Prato; rhodium catalysis; fullerene dimer; HPLC; amino acid; cyclo addition; alkylation; solubility;

    Abstract : This bachelor thesis covers the initial development of a synthesis of fullerene dimers using two different types of linking reactions. Different setups for [3+2] cycloadditions to fullerenes (Prato reaction) were tested, and for that purpose, an N-alkylated amino acid was synthesised. READ MORE
