  1. 1. Probing ion movement in conjugated polymers

    University essay from Uppsala universitet/Strukturkemi

    Author : Markus Hall; [2019]
    Keywords : Light-emitting electrochemical cell; conjugated polymer; electrochemical doping; MEH-PPV; lithium; trifluoromethanesulfonate; trimethylolpropane ethoxylate;

    Abstract : Electronic conduction in conjugated polymers can be increased through electrochemical doping. This is utilised in light-emitting electrochemical cells and allows for a less demanding manufacturing process compared to the related organic light-emitting diode. READ MORE

  3. 2. Modification of a transient EPR and photoluminescence detection setup

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Olof Grund; [2017]
    Keywords : EPR; photo luminescence; FSC2;

    Abstract : Climate change has given rise to higher demand of renewable energy. Conventional non-organic solar cells are still seen the most on the market but the last 10-20 years there has been an exponential increase in research about organic solar cells. READ MORE
