  • Determination of the Contact Resistivity of Screen-printed Al Contacts Formed by Laser Contact Opening 
    Kranz, Christopher; Lim, Bianca; Baumann, Ulrike; Dullweber, Thorsten (London : Elsevier Ltd., 2015)
    Next-generation industrial PERC solar cells typically include local laser contact opening (LCO) of a dielectric passivation layer stack at the rear side and subsequent full-area aluminum screen printing and firing. In this ...
  • Industrial cleaning sequences for Al2O3-passivated PERC solar cells 
    Kranz, Christopher; Wyczanowski, Sabrina; Baumann, Ulrike; Dorn, Silke; Queisser, Steffen; Schweckendiek, Jürgen; Pysch, Damian; Dullweber, Thorsten (London : Elsevier Ltd., 2014)
    In this paper, we investigate different industrial applicable cleaning sequences on test wafers and PERC solar cells in comparison to a laboratory type RCA clean. The cleaning sequences pSC1, HF/HCl, HF/O3 and HF/O3 show ...
  • Wet chemical polishing for industrial type PERC solar cells 
    Kranz, Christopher; Wyczanowski, Sabrina; Baumann, Ulrike; Weise, Katrin; Klein, Cornelia; Delahaye, Franck; Dullweber, Thorsten; Brendel, Rolf (Amsterdam : Elsevier, 2013)
    Industrial PERC cell process flows typically apply the polishing of the rear side after texturing as well as the edge isolation after POCl3 diffusion. In this paper, we present a novel single step polishing process which ...
