    • openAccess   Formation Criteria of High Efficiency Perovskite Solar Cells in Ambient Conditions 

      Aranda Alonso, Clara; Cristobal, Cesar; Shooshtari, Leyla; Li, Cheng; Huettner, Sven; Guerrero, Antonio Royal Society of Chemistry (2017)
      The field of lead halide perovskites for solar cell applications has recently reported impressive power conversion (PCE) above 22 % using complex mixed cation formulations. Very importantly, highest PCE have been obtained ...

    • closedAccess   Interactive theatre via mixed reality and Ambient Intelligence 

      Vasilakos, Athanasios V.; Wei, Liu; Nguyen, Ta Huynh Duy; Qui, Tran Cong Thien; Chen, Li Cheng; Boj, Clara; Díaz García, Diego José; Cheok, Adrian David; Marentakis, Georgios Elsevier (2008-02)
      Our system of Mixed Reality and 3D Live with Ambient Intelligence (AmI) is indented to bring performance art to the people while offering to the performance artists a creative tool to extend the grammar of the traditional ...

    • openAccess   Origins and mechanisms of hysteresis in organometal halide perovskites 

      Li, Cheng; Guerrero, Antonio; Zhong, Yu; Huettner, Sven IOP (2017-04)
      Inorganic–organic halide organometal perovskites, such as CH3NH3PbI3 and CsPbI3, etc, have been an unprecedented rising star in the field of photovoltaics since 2009, owing to their exceptionally high power conversion ...

    • 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 ...

    • openAccess   Unravelling the role of vacancies in lead halide perovskite through electrical switching of photoluminescence 

      Li, Cheng; Guerrero, Antonio; Huettner, Sven; Bisquert, Juan Nature Research (2018)
      We address the behavior in which a bias voltage can be used to switch on and off the photoluminescence of a planar film of methylammonium lead triiodide perovskite (MAPbI3) semiconductor with lateral symmetric electrodes. ...
