  • Advances in the surface passivation of silicon solar cells 
    Schmidt, Jan; Werner, Florian; Veith, Boris; Zielke, Dimitri; Steingrube, S.; Altermatt, Pietro P.; Gatz, Sebastian; Dullweber, Thorsten; Brendel, Rolf (Amsterdam : Elsevier BV, 2012)
    The surface passivation properties of aluminium oxide (Al 2O 3) on crystalline Si are compared with the traditional passivation system of silicon nitride (SiN x). It is shown that Al 2O 3 has fundamental advantages over ...
  • Identifying the location of recombination from voltage-dependent quantum efficiency measurements 
    Min, Byungsul; Kruse, Christian; Schinke, Carsten; Wolf, Martin; Müller, Matthias; Sträter, Hendrik; Wagner, Matthias; Bothe, Karsten; Brendel, Rolf (London : Elsevier Ltd., 2017)
    This paper investigates process-induced variations of the open-circuit voltage (Voc) using voltage-dependent quantum efficiency measurements. By means of device modelling we show that this method is able to explain the Voc ...
  • Temperature-dependence of polymer grating couplers for single-mode waveguides 
    Li, Pei; Sherman, Stanislav; Rezem, Maher; Honnef, Kirsten; Zappe, Hans (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    Polymer optical sensors have attracted significant scientific interest due to the advantages of flexibility and low-cost mass-production possibilities. A main challenge in integration of all-polymer systems is interfacing ...
