    • Current status of outdoor lifetime testing of organic photovoltaics 

      Zhang, Yiwei; Samuel, Ifor D. W.; Wang, Tao; Lidzey, David G. (2018-08) - Journal item
      Performance degradation is one of the key obstacles limiting the commercial application of organic photovoltaic (OPV) devices. The assessment of OPV stability and lifetime are usually based on simulated degradation experiments ...
    • 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 ...
    • On the molecular origin of charge separation at the donor-acceptor interface 

      Sini, Gjergji; Schubert, Marcel; Risko, Chad; Roland, Steffen; Lee, Olivia; Chen, Zhihua; Richter, Thomas; Dolfen, Daniel; Coropceanu, Veaceslav; Ludwigs, Sabine; Scherf, Ullrich; Facchetti, Antonio; Fréchet, Jean; Neher, Dieter (2018-04) - Journal article
      Fullerene-based acceptors have dominated organic solar cells for almost two decades. It is only within the last few years that alternative acceptors rival their dominance, introducing much more flexibility in the optoelectronic ...
