    • In-situ studies of multicrystalline silicon nucleation and growth on alpha- and beta-Si3N4 coated substrates 

      Undheim, Espen; Maeda, Kensaku; Arnberg, Lars; Holmestad, Randi; Fujiwara, Kozo; Di Sabatino Lundberg, Marisa (Journal article; Peer reviewed, 2018)
      The growth of silicon on various nitride coated quartz substrates were studied using in-situ observation of the solidification process. Three different coating types were used: One consisting entirely of α-Si3N4 particles, ...

    • Nucleation and growth of multicrystalline silicon 

      Undheim, Espen (Doctoral theses at NTNU;2018:42, Doctoral thesis, 2018)
      This work has focused on the nucleation process of multicrystalline silicon (mc-Si) for photovoltaic (PV) applications during solidification in α-Si3N4 coated crucibles, the typical crucible coating used commercially. ...

    • Orientation relationship between b-Si3N4 and Si in multicrystalline silicon ingots for PV applications 

      Undheim, Espen; Vullum, Per Erik; Holmestad, Randi; Arnberg, Lars; Di Sabatino Lundberg, Marisa (Journal article; Peer reviewed, 2018)
      β-Si3N4 particles are thought to be nucleation sites for silicon in multicrystalline silicon (mc-Si) ingots for PV applications. The orientation relationship (OR) between Si and β-Si3N4 has been investigated by transmission ...
