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 ... -
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 ... -
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 ... -
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 ... -
Understanding the Improvement in the Stability of a Self-Assembled Multiple-Quantum Well Perovskite Light-Emitting Diode
Cheng, Li; Wang, Nana; Guerrero, Antonio; Zhong, Yu; Long, Huan; Miao, Yanfeng; Bisquert, Juan; WANG, JIANPU; Huettner, Sven American Chemical Society (2020-11-07)We fabricate two-dimensional Ruddlesden–Popper layered perovskite films by introducing 1-naphthylmethylamine iodide into the precursor, which forms a self-assembled multiple-quantum well (MQW) structure. Enabling outstanding ... -
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. ...
