  • Single Print Metal Stencils for High-efficiency PERC Solar Cells 
    Hannebauer, H.; Falcon, T.; Cunnusamy, J.; Dullweber, Thorsten (London : Elsevier Ltd., 2016)
    Industrial silicon solar cells like Passivated Emitter and Rear Cells (PERC) typically apply a screen-printed (Ag) front contact with a single print process using a mesh screen. It has been shown that using stencils instead ...
  • 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 ...
  • The effect of oxide precipitates on minority carrier lifetime in n-type silicon 
    Murphy, J.D.; Al-Amin, M.; Bothe, K.; Olmo, M.; Voronkov, V.V.; Falster, R.J. (College Park, MD : American Institute of Physics, 2015)
    Supersaturated levels of interstitial oxygen in Czochralski silicon can lead to the formation of oxide precipitates. Although beneficial from an internal gettering perspective, oxygen-related extended defects give rise to ...
  • Tools and Strategies for Grinding of Riblets on Freeformed Compressor Blades 
    Denkena, Berend; Grove, Thilo; Krawczyk, T. (Amsterdam : Elsevier BV, 2016)
    A major goal in the design of turbomachinery is the increase of efficiency. To attain this increase, the flow losses must be reduced. A substantial proportion of the losses is generated by skin friction between compressor ...
  • Towards highly efficient polymer fiber laser sources for integrated photonic sensors 
    Spelthann, Simon; Unland, Stefanie; Thiem, Jonas; Jakobs, Florian; Kielhorn, Jana; Ang, Pen Yiao; Johannes, Hans-Hermann; Kracht, Dietmar; Neumann, Joerg; Ruehl, Axel; Kowalsky, Wolfgang; Ristau, Detlev (Basel : MDPI AG, 2020)
    Lab-on-a-Chip (LoC) devices combining microfluidic analyte provision with integrated optical analysis are highly desirable for several applications in biological or medical sciences. While the microfluidic approach is ...
