• 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 ...
    • closedAccess   Slow dynamic processes in lead halide perovskite solar cells. Characteristic times and hysteresis 

      S. Sánchez, Rafael; González Pedro, Victoria; Lee, Jin Wook; Park, Nam-Gyu; Kang, Yong Soo; Mora-Sero, Ivan; Bisquert, Juan American Chemical Society (2014-06)
      Characteristic times of perovskite solar cells (PSCs) have been measured by different techniques: transient photovoltage decay, transient photoluminescence, and impedance spectroscopy. A slow dynamic process is detected ...
