  • 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 ...
  • Hahn, Jan (Garbsen : TEWISS Verlag, 2020)
    Von der Alterssichtigkeit ist jeder Mensch ab ca. 45 Jahren betroffen. Bei einer neuartigen Behandlungsmethode (fs-Lentotomie) wird mit dem Laser versucht der altersbedingten Linsenverhärtung entgegenzuwirken. Bislang ...
  • Matthias, Steffen; Kästner, Markus; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    Inspection of machine elements is an important task in production processes in order to ensure the quality of produced parts and to gather feedback for the continuous improvement process. A new measuring system is presented, ...
  • Chatzizyrli, Elisavet; Tinne, Nadine; Lachmayer, Roland; Neumann, Jörg; Kracht, Dietmar (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    The development of laser-based lighting systems has been the latest step towards a revolution in illumination technology brought about by solid-state lighting. Laser-activated remote phosphor systems produce white light ...
  • Vogt, Malte R.; Holst, Hendrik; Winter, Matthias; Brendel, Rolf; Altermatt, Pietro P. (Amsterdam : Elsevier, 2015)
    Commonly, the thermal behavior of solar cell modules is calculated with analytical approaches using non wavelength-dependent optical data. Here, we employ ray tracing of entire solar modules at wavelengths of 300-2500 nm ...

    We measure and discuss the complex refractive index of conventional ethylene vinyl acetate (EVA) and an EVA with enhanced UV-transmission based on spectroscopic ellipsometry, transmission and reflection measurements over ...
  • 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, ...
  • Chatzizyrli, Elisavet; Tinne, Nadine; Lachmayer, Roland; Neumann, Jörg; Kracht, Dietmar (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    A new family of lighting products is developed as laser diodes replace LEDs in the remote phosphor configuration. The resulting lighting systems, also known as laser-excited remote phosphor systems, exhibit advanced ...
  • 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 ...
