  • 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. ...
  • Chen, Yan; Zhang, Yang; Yuan, Feifei; Ding, Fei; Schmidt, Oliver G. (Hoboken, NJ : Blackwell Publishing Ltd, 2017)
    The rapid advancements of wearable electronics require continued innovation in sustainable power sources and human interactive sensors. An abundance of energy in various forms, such as mechanical, thermal, optical, and ...
  • Schnabel, Roman; LIGO Scientific Collaboration (Les Ulis : EDP Sciences, 2013)
    This contribution reviews our recent progress on the generation of squeezed light [1], and also the recent squeezed-light enhancement of the gravitational wave detector GEO 600 [2]. GEO 600 is currently the only GW observatory ...
  • 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 ...
  • 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 ...
  • Mubarak, Riyad; Hofmann, Martin; Riechelmann, Stefan; Seckmeyer, Gunther (Basel : MDPI AG, 2017)
    This work assesses the performance of five transposition models that estimate the global and diffuse solar irradiance on tilted planes based on the global horizontal irradiance. The modelled tilted irradiance values are ...
  • 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 ...
  • Kanthasamy, Karthiga; Pfnür, Herbert (Frankfurt am Main : Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2015)
    The contacts and the chemical bonds formed between metallic electrodes and molecules determine to a large extent the conductive properties of single molecular junctions, which represent the smallest possible active elements ...
  • Das, S.K.; Bock, M.; Grunwald, R.; Borchers, B.; Hyyti, J.; Steinmeyer, Günter; Ristau, Detlev; Harth, A.; Vockerodt, T.; Nagy, T.; Morgner, Uwe (Les Ulis : EDP Sciences, 2013)
    The third harmonic of a few-cycle pulse, generated at different dielectric surfaces, is investigated using interferometric frequency-resolved optical gating. We present direct experimental evidence for a non-instantaneous ...
  • 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 ...
  • Johannsmeier, Sonja; Heeger, Patrick; Terakawa, Mitsuhiro; Kalies, Stefan; Heisterkamp, Alexander; Ripken, Tammo; Heinemann, Dag (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Gold nanoparticle mediated laser stimulation of neuronal cells allows for cell activation on a single-cell level. It could therefore be considered an alternative to classical electric neurostimulation. The physiological ...
  • Niepelt, Raphael; Hensen, Jan; Knorr, Alwina; Steckenreiter, Verena; Kajari-Schröder, Sarah; Brendel, Rolf (Amsterdam : Elsevier, 2014)
    Kerfless wafering techniques offer a significant cost saving potential via the reduction of silicon consumption. In this paper, we examine thin single crystalline Si foils that were fabricated by a novel kerfless ...
  • Knigge, Christoph; Raasch, Siegfried (Amsterdam : Elsevier, 2016)
    High resolution large-eddy simulations (LES) were carried out to simulate the turbulent flow of the atmospheric boundary layer during an idealized strong-wind event in order to verify discrete gust models like the ...
  • Kiefer, Fabian; Brendemühl, Till; Berger, Miriam; Lohse, Anja; Kirstein, Sabine; Braun, Nadja; Lehr, Martin; Heinemeyer, Frank; Jung, Verena; Morlier, Arnaud; Blankemeyer, Susanne; Kunze, Iris; Winter, Renate; Harder, Nils-Peter; Dullweber, Thorsten; Köntges, Marc; Brendel, Rolf (Amsterdam : Elsevier, 2013)
    The majority of screen printed solar cells has silver pads at the rear side to enable soldering for the module manufacturing. The pads increase the recombination at the silicon/metal interface due to the absence of a back ...
  • 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 ...
  • Koch, Matthias; Suhr, Christian; Roth, Bernhard; Meinhardt-Wollweber, Merve (Chichester : John Wiley and Sons Ltd, 2016)
    In vivo Raman spectroscopy with low signal-to-noise ratio and strong, irregularly shaped fluorescence background imposes a challenge for automatic baseline correction methods. In this work, an approach that enables fast ...
