• openAccess   Cooperative kinetics of depolarization in CH3NH3PbI3 perovskite solar cells 

      Bertoluzzi, Luca; S. Sánchez, Rafael; Liu, Linfeng; Lee, Jin Wook; Mas, Elena; Han, Hongwei; Park, Nam-Gyu; Mora-Sero, Ivan; Bisquert, Juan Royal Society of Chemistry (2015)
      Despite the large photovoltaic performance recently achieved, many aspects of the working principles of hybrid organic–inorganic perovskite solar cells remain to be unveiled. We analyze the experimental features observed ...
    • openAccess   Mechanism of carrier accumulation in perovskite thin-absorber solar cells 

      Mora-Sero, Ivan; González Pedro, Victoria; Fabregat-Santiago, Francisco; Juarez-Perez, Emilio J.; Kim, Hui-Seon; Park, Nam-Gyu; Bisquert, Juan Nature Publishing Group (2013)
      Photovoltaic conversion requires two successive steps: accumulation of a photogenerated charge and charge separation. Determination of how and where charge accumulation is attained and how this accumulation can be identified ...
