    • High-Bandgap Perovskite Materials for Multijunction Solar Cells 

      Yang, T. C. J.; Fiala, P.; Jeangros, Q.; Ballif, C. (2018)
      High-bandgap (>1.7 eV) mixed halide perovskites for multijunction solar cells are usually affected by photoinduced phase segregation, which triggers subbandgap defects that are detrimental to the open-circuit voltage. While ...

    • Hybrid sequential deposition process for fully textured perovskite/silicon tandem solar cells 

      Sahli, F.; Werner, J.; Kamino, B. A.; Brauninger, M.; Yang, T. C. J.; Fiala, P.; et al. (2018)
      Tandem solar cells that feature a high-bandgap perovskite cell on top of a lower bandgap silicon cell have the potential to reach efficiencies > 30%. Here, we present a versatile hybrid deposition method that yields conformal ...

    • Instability of p-i-n perovskite solar cells under reverse bias 

      Razera, R.A.Z.; Jacobs, D. A.; Fu, F.; Fiala, P.; Dussouillez, M.; Sahli, F.; Yang, T.C.J.; Ding, L.; Walter, A.; Feil, A. F.; Boudinov, H. I.; Nicolay, S.; Ballif, C.; Jeangros, Q. (2020-01)
      Partial shading can trigger permanent damage in photovoltaic modules because the illuminated solar cells drive the shaded cells into reverse bias. Under reverse bias conditions, perovskite solar cells have been shown to ...
