  • Leuteritz, Georg; Lachmayer, Roland (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    Individually shaped light distributions become more and more important in lighting technologies and thus the importance of additively manufactured reflectors increases significantly. The vast field of applications ranges ...

    Design and synthesis of multi-dimensional metal-organic frameworks are fascinating because MOFs possess intriguing structures and unique properties and exhibit potential applications in photocatalysis. In the present study, ...
  • Stang, Johann-Christoph; Hendrichs, Max-Sebastian; Merkle, Agnes; Peibst, Robby; Stannowski, Bernd; Korte, Lars; Rech, Bernd (London : Elsevier Ltd., 2017)
    We report on two different approaches to fabricate interdigitated back contact silicon heterojunction solar cells without using indium tin oxide (ITO). The standard ITO/Ag backend is either modified by replacing ITO with ...
  • Höhl, Martin; Detemple, Daphne; Lyutenski, Stefan; Leuteritz, Georg; Varkentin, Arthur; Schmitt, Heike Andrea; Lenarz, Thomas; Roth, Bernhard; Meinhardt-Wollweber, Merve; Morgner, Uwe (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Optical techniques are effective tools for diagnostic applications in medicine and are particularly attractive for the noninvasive analysis of biological tissues and fluids in vivo. Noninvasive examinations of substances ...
  • Witteck, Robert; Schulte-Huxel, Henning; Holst, Hendrik; Hinken, David; Vogt, Malte R.; Blankemeyer, Susanne; Köntges, Marc; Bothe, Karsten; Brendel, Rolf (London : Elsevier Ltd., 2016)
    Improving the light trapping in a module results in an increase in the generated current. Consequently, an optimization of the front grid metallization of the cell is required for the best trade-off between series resistance, ...
  • Reiter, Sina; Koper, Nico; Reineke-Koch, Rolf; Larionova, Yevgeniya; Turcu, Mircea; Krügener, Jan; Tetzlaff, Dominic; Wietler, Tobias; Höhne, Uwe; Kähler, Jan-Dirk; Brendel, Rolf; Peibst, Robby (London : Elsevier Ltd., 2016)
    We investigate the optical properties of n- and p-type polycrystalline silicon (poly-Si) layers. We determine the optical constants n and k of the complex refractive index of polycrystalline silicon by using variable-angle ...
  • Turowski, Marcus; Jupé, Marco; Ehlers, Henrik; Melzig, Thomas; Pflug, Andreas; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    Simulation and modeling find more and more their way into thin film technology. Beside theoretical models for layer design, pre-production design analysis, and real time process control, atomistic simulation techniques ...
  • Sardana, Neha; Birr, Tobias; Schlenker, Sven; Reinhardt, Carsten; Schilling, Jörg (Bristol : IOP Publishing Ltd., 2014)
    The dispersion relation and propagation of surface plasmons polaritons (SPPs) on nanoporous gold films is experimentally investigated and an increasing red shift of the SPPs is observed with rising porosity. This is caused ...
