    • Controlling exciton diffusion and fullerene distribution in photovoltaic blends by side chain modification 

      Sajjad, Muhammad Tariq; Ward, Alexander J.; Kästner, Christian; Ruseckas, Arvydas; Hoppe, Harald; Samuel, Ifor David William (2015-08-06) - Journal article
      The influence of crystallinity on exciton diffusion and fullerene distribution was investigated by blending amorphous and semicrystalline copolymers. We measured exciton diffusion and fluorescence quenching in such blends ...
    • Exciton diffusion length and charge extraction yield in organic bilayer solar cells 

      Siegmund, Bernhard; Sajjad, Muhammad Tariq; Widmer, Johannes; Ray, Debdutta; Koerner, Christian; Riede, Moritz; Leo, Karl; Samuel, Ifor David William; Vandewal, Koen (2017-03-28) - Journal article
      A method for resolving the diffusion length of excitons and the extraction yield of charge carriers is presented based on the performance of organic bilayer solar cells and careful modeling. The technique uses a simultaneous ...
