    • openAccess   Potassium ions as a kinetic controller in ionic double layers for hysteresis-free perovskite solar cells 

      kim, Seul-Gi; Cheng, Li; Guerrero, Antonio; Kim, June-Mo; Zhong, Yu; Bisquert, Juan; Huettner, Sven; Park, Nam-Gyu Royal Society of Chemistry (2019-07-22)
      Since ion migration and interaction with external contacts has been regarded as one of the origins for photocurrent density (J)–voltage (V) hysteresis and phase segregation in perovskite solar cells (PSCs) under operational ...

    • openAccess   Real-Time Observation of Iodide Ion Migration in Methylammonium Lead Halide Perovskites 

      Li, Cheng; Guerrero, Antonio; Yu, Zhong; Gräser, Anna; Melo Luna, Carlos Andres; Köhler, Jürgen; Bisquert, Juan; Hildner, Richard; Huettner, Sven Wiley (2017)
      Organic-inorganic metal-halide perovskites (e.g. CH3NH3PbI3-xClx) emerged as a promising opto-electronic material. However, the Shockley–Queisser Limit for the power conversion efficiency (PCE) of perovskite-based photovoltaic ...
