    • closedAccess   Control of I–V Hysteresis in CH3NH3PbI3 Perovskite Solar Cell 

      Kim, Hui-Seon; Jang, In-Hyuk; Ahn, Namyoung; Choi, Mansoo; Guerrero, Antonio; Bisquert, Juan; Park, Nam-Gyu ACS Publications (2015-11-09)
      Mismatch of current (I)-voltage (V) curves with respect to the scan direction, so-called I–V hysteresis, raises critical issue in MAPbI3 (MA = CH3NH3) perovskite solar cell. Although ferroelectric and ion migration have ...

    • 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 ...
