• 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 ...
    • 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 ...
