  • Competitive gettering of iron in silicon photovoltaics: Oxide precipitates versus phosphorus diffusion 
    Murphy, J.D.; McGuire, R.E.; Bothe, K.; Voronkov, V.V.; Falster, R.J. (American Institute of Physics Inc., 2014)
    Experiments have been conducted to understand the behaviour of iron in silicon containing oxide precipitates and associated defects (dislocations and stacking faults), which is subjected to phosphorus diffusion gettering. ...
  • Fundamental consideration of junction formation strategies for phosphorus-doped emitters with J0e < 10 fA/cm2 
    Min, Byungsul; Krügener, Jan; Müller, Matthias; Bothe, Karsten; Brendel, Rolf (London : Elsevier Ltd., 2017)
    This work shows the potential of further optimization of phosphorus-doped emitters in p-type silicon solar cells. We investigate the impact of different combinations of phosphorus doping profiles and surface passivation ...
  • Long-term soil warming decreases microbial phosphorus utilization by increasing abiotic phosphorus sorption and phosphorus losses 
    Tian, Ye; Shi, Chupei; Malo, Carolina Urbina; Kwatcho Kengdo, Steve; Heinzle, Jakob; Inselsbacher, Erich; Ottner, Franz; Borken, Werner; Michel, Kerstin; Schindlbacher, Andreas; Wanek, Wolfgang ([London] : Nature Publishing Group UK, 2023)
    Phosphorus (P) is an essential and often limiting element that could play a crucial role in terrestrial ecosystem responses to climate warming. However, it has yet remained unclear how different P cycling processes are ...
  • Minority carrier lifetime in silicon photovoltaics: The effect of oxygen precipitation 
    Murphy, J.D.; McGuire, R.E.; Bothe, K.; Voronkov, V.V.; Falster, R.J. (London : Elsevier Ltd., 2014)
    Single-crystal Czochralski silicon used for photovoltaics is typically supersaturated with interstitial oxygen at temperatures just below the melting point. Oxide precipitates therefore can form during ingot cooling and ...
  • Root adaptations to soils with low fertility and aluminium toxicity 
    Rao, Idupulapati M.; Miles, John W.; Beebe, Stephen E.; Horst, Walter J. (Oxford : Oxford University Press, 2016)
    Background Plants depend on their root systems to acquire the water and nutrients necessary for their survival in nature, and for their yield and nutritional quality in agriculture. Root systems are complex and a variety ...
  • 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 ...
