  • Cuevas, Andres; Yan, Di; Haase, Felix; Petermann, Jan-Hendrik; Brendel, Rolf (Amsterdam : Elsevier, 2013)
    The optimization of solar cells with localized rear contacts usually requires numerical simulation. Here we compare Sentaurus Device to a simpler Conductive Boundary (CoBo) simulator and to an approximate Geometric model. ...
  • Altermatt, Pietro P.; McIntosh, Keith R. (Amsterdam : Elsevier, 2014)
    Presently, the crystalline silicon (c-Si) photovoltaic (PV) industry is switching from standard cells to PERC cells to increase cell efficiency from about 18% to about 20%. This paper gives a roadmap for increasing PERC ...

    Laser Induced Breakdown Spectroscopy (LIBS) has the potential to allow direct, standoff measurement of contaminants on nuclear plant. Here, LIBS is evaluated as an analytical tool for measurement of Sr and Cs contamination ...
  • Holst, Hendrik; Winter, Matthias; Vogt, Malte R.; Bothe, Karsten; Köntges, Marc; Brendel, Rolf; Altermatt, Pietro P. (Amsterdam : Elsevier, 2013)
    While ray tracing of solar cells was established decades ago, ray tracing of entire modules has met obstacles, mainly because module optics are affected by geometric structures varying over a large scale of dimensions. In ...
  • Needleman, David Berney; Wagner, Hannes; Altermatt, Pietro P.; Buonassisi, Tonio (Amsterdam : Elsevier, 2015)
    Advanced solar cell architectures like passivated emitter and rear (PERC) and heterojunction with intrinsic thin layer (HIT) are increasingly sensitive to bulk recombination. Present device models consider homogeneous bulk ...

    Strains of the Gram-negative bacterium Vibrio coralliilyticus cause the bleaching of corals due to decomposition of symbiotic microalgae. The V. coralliilyticus strain ATCC BAA-450 (Vc450) encodes a type III secretion ...
  • Ali, Adnan; Ohrdes, Tobias; Wagner, Hannes; Altermatt, Pietro P. (Amsterdam : Elsevier, 2014)
    It is often stated that one of the main advantages of back-contacted (BC) Si solar cells over standard cells is that shading due to the front-finger metallization is avoided - while it is also often stated that BC cells ...
  • Herlufsen, Sandra; Bothe, Karsten; Brendel, Rolf; Schmidt, Jan (Amsterdam : Elsevier, 2014)
    We investigate the impact of an injection-dependent carrier lifetime in crystalline silicon on dynamic photoluminescence lifetime imaging (dynamic PLI). Although the dynamic lifetime approach is a technique that evaluates ...
  • Käsewieter, Jörg; Kajari-Schröder, Sarah; Niendorf, Thomas; Brendel, Rolf (Amsterdam : Elsevier, 2013)
    Ultra-thin silicon wafer have to withstand forces and stresses during handling procedures without breakage. Here we investigate the failure stresses of ?30 ?m thick monocrystalline silicon films produced with the porous ...
  • Hannebauer, Helge; Dullweber, Thorsten; Falcon, Tom; Brendel, Rolf (Amsterdam : Elsevier, 2013)
    In this paper, we investigate and compare three different fine line printing techniques for the silver front side metallization of industrial-type silicon solar cells: single print, dual print and print-on-print. We produce ...
  • Arndt, Markus; Bassi, Angelo; Giulini, Domenico; Heidmann, Antoine; Raimond, Jean-Michel (Amsterdam : Elsevier BV, 2011)
    We discuss recent studies on the foundations of quantum physics with photonic, atomic, molecular and micromechanical systems as well as theoretical treatments of the interface between quantum physics and classical observations. ...
  • Zuber, Ralf; Ribnitzky, Mario; Tobar, Mario; Lange, Kezia; Kutscher, Dimitrij; Schrempf, Michael; Niedzwiedz, Angelika; Seckmeyer, Gunther (Bristol : Institute of Physics Publishing, 2018)
    Solar spectral irradiance measured by two recently developed array spectroradiometers (called UV-BTS and VIS-BTS) are compared to the results of a scanning double monochromator system which is certified as a travelling ...
  • Krawinkel, Judith; Torres-Mapa, Maria Leilani; Werelius, Kristian; Heisterkamp, Alexander; Rüttermann, Stefan; Romanos, Georgios E.; Gerhardt-Szép, Susanne (Basel : MDPI AG, 2016)
    Interaction of gold nanoparticles (AuNPs) in the vicinity of cells' membrane with a pulsed laser (λ = 532 nm, τ = 1 ns) leads to perforation of the cell membrane, thereby allowing extracellular molecules to diffuse into ...

    Stimulation of neuronal cells generally resorts to electric signals. Recent advances in laser-based stimulation methods could present an alternative with superior spatiotemporal resolution. The avoidance of electronic ...
  • Chatterjee, Soumya; Datta, Sibnarayan; Sharma, Sonika; Tiwari, Sarika; Gupta, Dharmendra K. (Warsaw : De Gruyter Open Ltd, 2017)
    Life on Earth harbours an unimaginable diversity of microbial communities. Among these, gut microbiome, the ecological communities of commensal, symbionts (bacteria and bacteriophages) are a unique assemblage of microbes. ...
