    • closedAccess   Assessing possibilities and limits for solar cells 

      Nayak, Pabitra K.; Bisquert, Juan; Cahen, David Wiley (2011-05-05)
      What are the solar cell efficiencies that we can strive towards? We show here that several simple criteria, based on cell and module performance data, serve to evaluate and compare all types of today's solar cells. Analyzing ...

    • openAccess   In Operando, Photovoltaic, and Microscopic Evaluation of Recombination Centers in Halide Perovskite-Based Solar Cells 

      Zohar, Arava; Kulbak, Michael; Turren Cruz, Silver Hamill; Nayak, Pabitra K.; Kama, Adi; Hagfeldt, Anders; Snaith, Henry J.; Hodes, Gary; Cahen, David American Chemical Society (2022-08-03)
      The origin of the low densities of electrically active defects in Pb halide perovskite (HaP), a crucial factor for their use in photovoltaics, light emission, and radiation detection, remains a matter of discussion, in ...

    • closedAccess   Photovoltaic efficiency limits and material disorder 

      Nayak, Pabitra K.; Garcia-Belmonte, Germà; Kahn, Antoine; Bisquert, Juan; Cahen, David Royal Society of Chemistry (2012)
      Solar cells based on crystalline semiconductors such as Si and GaAs provide nowadays the highest performance, but photovoltaic (PV) cells based on less pure materials, such as poly- or nano-crystalline or amorphous inorganic ...
