  • Analysis of local Al-doped back surface fields for high efficiency screen-printed solar cells 
    Gatz, Sebastian; Bothe, Karsten; Müller, Jens; Dullweber, Thorsten; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)
    In this paper, we investigate the surface recombination of local screen-printed aluminum contacts applied to rear passivated solar cells. We measure the surface recombination velocity by microwave-detected photoconductance ...
  • Manufacturing conditioned wear of all-ceramic knee prostheses 
    Denkena, Berend; Köhler, Jens; Turger, Anke; Helmecke, Patrick; Correa, Tomas A.; Hurschler, Christof (Amsterdam : Elsevier, 2013)
    To date, bioceramics have not been applied successfully in total knee joint endoprostheses. Sintered bioceramics can be machined only by grinding and polishing processes. Due to high quality requirements, there are significant ...
  • Recombination at local aluminum-alloyed silicon solar cell base contacts by dynamic infrared lifetime mapping 
    Müller, Jens; Bothe, Karsten; Gatz, Sebastian; Plagwitz, Heiko; Schubert, Gunnar; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)
    The application of local aluminum (Al)-alloyed contacts to the p-type base of silicon solar cells reduces minority charge carrier recombination due to the formation of a local back surface field (LBSF). We study the ...
