    • Metallization of Si heterojunction solar cells by nanosecond laser ablation and Ni-Cu plating 

      Dabirian, A.; Lachowicz, A.; Schuttauf, J. W.; Paviet-Salomon, B.; Morales-Masis, M.; Hessler-Wyser, A.; et al. (2017)
      A key step in industrialization of photovoltaics (PV) is the development of low-cost and large-area metallization processes to substitute the standard screen-printing process of silver paste. Thus Cu and Ni metallization ...
    • Quantifying competitive grain overgrowth in polycrystalline ZnO thin films 

      Aebersold, A. B.; Fanni, L.; Hessler-Wyser, A.; Nicolay, S.; Ballif, C.; Hebert, C.; et al. (2019)
      The grain size evolution of polycrystalline thin films, which form by competitive grain overgrowth as commonly interpreted using the van der Drift model, is understood to follow a power-law scaling of the average grain ...
    • Zinc blende-wurtzite polytypism in nanocrystalline ZnO films 

      Aebersold, A. B.; Fanni, L.; Hessler-Wyser, A.; Nicolay, S.; Ballif, C.; Hebert, C.; et al. (2017)
      ZnO is commonly observed and assumed to crystallize fully in a wurtzite structure. Indeed, While polytypism between a wurtzite and a zinc blende phase is often seen in some II-VI compounds, it has only rarely been observed ...
