  • Fischer, G.; Müller, M.; Wagner, Hannes; Steingrube, S.; Altermatt, Pietro P. (Amsterdam : Elsevier BV, 2012)
    Monitoring the I-V parameters in mass production yields a distribution that cannot be understood in a simple manner. For example, if Voc varies greatly, it is not obvious whether this is mainly due to variations in the ...
  • 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 ...
  • Gatz, Sebastian; Müller, Jens; Dullweber, Thorsten; Brendel, Rolf (Amsterdam : Elsevier BV, 2012)
    In this paper, we investigate the impact of the rear surface passivation, the silicon base material and the local aluminum contacts applied to rear side passivated solar cells with a homogenously doped emitter at the front. ...
  • Veith, Boris; Dullweber, Thorsten; Siebert, M.; Kranz, Christopher; Werner, Florian; Harder, Nils-Peter; Schmidt, Jan; Roos, B.F.P.; Dippell, T.; Brendel, Rolf (Amsterdam : Elsevier BV, 2012)
    The deposition rate of the standard (i.e. sequential) atomic layer deposition (ALD) process is very low compared to the plasma-enhanced chemical vapour deposition (PECVD) process. Therefore, as a short- and medium-term ...
  • Gogolin, Ralf; Zielke, D.; Descoeudres, A.; Despeisse, M.; Ballif, C.; Schmidt, J. (London : Elsevier Ltd., 2017)
    In this study, we demonstrate the high surface passivation quality of PEDOT:PSS/c-Si junctions for the first time on solar cell level, reaching a record high Voc value of 688 mV after full-area metallization of the PEDOT:PSS. ...
  • Wagner, Hannes; Hofstetter, Jasmin; Mitchell, Bernhard; Altermatt, Pietro P.; Buonassisi, Tonio (Amsterdam : Elsevier Science BV, 2015)
    We present a numerical simulation study of different multicrystalline silicon materials and solar cell architectures to understand today's efficiency limitations and future efficiency possibilities. We compare conventional ...
  • Titova, V.; Veith-Wolf, B.; Startsev, D.; Schmidt, J. (London : Elsevier Ltd., 2017)
    We characterize the surface passivation properties of ultrathin titanium oxide (TiOx) films deposited by atomic layer deposition (ALD) on crystalline silicon by means of carrier lifetime measurements. We compare different ...
  • Müller, M.; Altermatt, Pietro P.; Schlegel, K.; Fischer, G. (Amsterdam : Elsevier BV, 2012)
    A method to derive the emitter saturation current density J0e with lateral resolution is applied to investigate selective emitter structures. The method uses PL lifetime imaging at several injection densities to laterally ...
  • 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 ...
  • Kruse, Christian N.; Wolf, Martin; Schinke, Carsten; Hinken, David; Brendel, Rolf; Bothe, Karsten (London : Elsevier Ltd., 2017)
    The fill factor determined from a measured current-voltage characteristic of a bare solar cell depends on the number and positions of the electrical contacting probes. Nine different geometries for contacting the front ...
  • Hofmann, Martin; Seckmeyer, Gunther (Basel : MDPI AG, 2017)
    We analyze the output of various state-of-The-Art irradiance models for photovoltaic systems. The models include two sun position algorithms, three types of input data time series, nine diffuse fraction models and five ...
  • Hannebauer, Helge; Schimanke, S.; Falcon, T.; Altermatt, Pietro P.; Dullweber, Thorsten (Amsterdam : Elsevier Science BV, 2015)
    We evaluate industrial-type PERC solar cells applying a dual printed front grid with stencil printed Ag fingers. We vary the Ag paste consumption for the finger print between 8.4 mg and 120.4 mg per 156 x 156 mm(2) wafer ...
  • Vogt, Malte R.; Holst, Hendrik; Schulte-Huxel, Henning; Blankemeyer, Susanne; Witteck, Robert; Bujard, Patrice; Kues, Jan-Bernd; Schinke, Carsten; Bothe, Karsten; Köntges, Marc; Brendel, Rolf (London : Elsevier Ltd., 2017)
    We evaluate the optical performance of PV modules with respect to an increase in short circuit current density. Our evaluation is based on the combination of ray tracing simulations and measurements on test modules with ...
  • Kühn, Timo; Altmikus, Andree; Daboul, Hussam; Radi, Alexander; Raasch, Siegfried; Knigge, Christoph; Böske, Lennart; Schwarz, Thorsten; Heister, Christoph; Langer-Möller, Annika; Lutz, Thorsten; Weihing, Pascal; Schulz, Christoph; Thiemeier, Jakob; Mockett, Charles; Fuchs, Marian; Thiele, Frank (Bristol : Institute of Physics Publishing, 2018)
    This article gives an overview of the results of the wind energy research project AssiSt. Results of the four work packages include flow in complex terrain, wind energy converters (WEC) in complex terrain subject to ...
  • Steckenreiter, V.; Walter, D.C.; Schmidt, J. (London : Elsevier Ltd., 2017)
    We analyze the lifetime evolution during permanent deactivation of the boron-oxygen-related defect center (BO defect) in boron-doped, oxygen-rich Czochralski-grown silicon (Cz-Si). In particular, we examine the impact of ...
