  • Analysis of local Al-doped back surface fields for high efficiency screen-printed solar cells 
    Gatz, Sebastian; Bothe, Karsten; Müller, Jens; Dullweber, Thorsten; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)
    In this paper, we investigate the surface recombination of local screen-printed aluminum contacts applied to rear passivated solar cells. We measure the surface recombination velocity by microwave-detected photoconductance ...
  • Comparison of the thermal stability of single Al2O3 layers and Al2O3/SiNx stacks for the surface passiviation of silicon 
    Veith, Boris; Werner, Florian; Zielke, Dimitri; Brendel, Rolf; Schmidt, Jan (Amsterdam : Elsevier BV, 2011)
    We measure surface recombination velocities (SRVs) below 10 cm/s on low-resistivity (1.4 Ωcm) p-type crystalline silicon wafers passivated with plasma-assisted and thermal atomic layer deposited (ALD) aluminium oxide (Al2O3) ...
  • Determination of the collection diffusion length by electroluminescence imaging 
    Schinke, Carsten; Hinken, David; Bothe, Karsten; Ulzhöfer, Christian; Milsted, Ashley; Schmidt, Jan; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)
    The electroluminescence emission of crystalline silicon solar cells at near-bandgap wavelengths is investigated. We show that the intensity of the emitted luminescence at near-bandgap wavelengths is directly proportional ...
  • Formation of locally aluminum-doped p-type silicon regions by in-line high-rate evaporation 
    Mader, Christoph; Bock, Robert; Müller, Jens; Schmidt, Jan; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)
    Locally aluminum-doped p-type silicon regions are formed by in-line high-rate evaporation of aluminum. We deposit aluminum layers of 28 μm thickness at dynamic deposition rates of 20 μm×m/min on locally laser-ablated Al2O3 ...
  • Giant photogalvanic effect in noncentrosymmetric plasmonic nanoparticles 
    Zhukovsky, Sergei V.; Babicheva, Viktoriia E.; Evlyukhin, Andrey B.; Protsenko, Igor E.; Lavrinenko, Andrei V.; Uskov, Alexander V. (College Park, MD : American Physical Society, 2014)
    Photoelectric properties of noncentrosymmetric, similarly oriented metallic nanoparticles embedded in a homogeneous semiconductor matrix are theoretically studied. Because of the asymmetric shape of the nanoparticle boundary, ...
  • High-rate atomic layer deposition of Al2O3 for the surface passivation of Si solar cells 
    Werner, Florian; Stals, Walter; Görtzen, Roger; Veith, Boris; Brendel, Rolf; Schmidt, Jan (Amsterdam : Elsevier BV, 2011)
    High-rate spatial atomic layer deposition (ALD) enables an industrially relevant deposition of high-quality aluminum oxide (Al2O3) films for the surface passivation of silicon solar cells. We demonstrate a homogeneous ...
  • Layer selective laser ablation for local contacts to thin emitters 
    Haase, Felix; Rojas, Enrique Garralaga; Bothe, Karsten; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)
    High efficiency solar cells require high generation and low recombination rates. High bulk lifetime, well passivated surfaces, and lowly doped thin emitters allow for low recombination rates. Thin passivated emitters should ...
  • Loss analysis and improvements of industrially fabricated Cz-Si solar cells by means of process and device simulations 
    Steingrube, S.; Wagner, Hannes; Hannebauer, Helge; Gatz, Sebastian; Chen, R.; Dunham, S.T.; Dullweber, Thorsten; Altermatt, Pietro P.; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)
    We model currently fabricated industrial-type screen-printed boron-doped Cz silicon solar cells using a combination of process and device simulations. The model reproduces the experimental results precisely and allows us ...
  • Minority carrier lifetime in silicon photovoltaics: The effect of oxygen precipitation 
    Murphy, J.D.; McGuire, R.E.; Bothe, K.; Voronkov, V.V.; Falster, R.J. (London : Elsevier Ltd., 2014)
    Single-crystal Czochralski silicon used for photovoltaics is typically supersaturated with interstitial oxygen at temperatures just below the melting point. Oxide precipitates therefore can form during ingot cooling and ...
  • Recombination at local aluminum-alloyed silicon solar cell base contacts by dynamic infrared lifetime mapping 
    Müller, Jens; Bothe, Karsten; Gatz, Sebastian; Plagwitz, Heiko; Schubert, Gunnar; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)
    The application of local aluminum (Al)-alloyed contacts to the p-type base of silicon solar cells reduces minority charge carrier recombination due to the formation of a local back surface field (LBSF). We study the ...
  • Solar cell emitter design with PV-tailored implantation 
    Ohrdes, Tobias; Steingrube, S.; Wagner, Hannes; Zechner, C.; Letay, G.; Chen, R.; Dunham, S.T.; Altermatt, Pietro P. (Amsterdam : Elsevier BV, 2011)
    A potentially cost-effective ion implanter for solar cells has become commercially available very recently. As the emitter dopant profiles differ from the standard diffusions, a combination of process simulation and device ...
  • Thermomechanical deformations in photovoltaic laminates 
    Paggi, M.; Kajari-Schröder, S.; Eitner, U. (London : SAGE Publications Ltd., 2011)
    Recent experimental results based on the digital image correlation technique (U. Eitner, M. Köntges, R. Brendel, Solar Energy Mater. Solar Cells, 2010, 94, 1346-1351) show that the gap between solar cells embedded into a ...
