    • 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 ...

    • openAccess   Lead Sulfide Nanocubes for Solar Energy Storage 

      Lemsi, Amira; Cardenas-Morcoso, Drialys; Haro, Marta; Gil Barrachina, Carlos; Aranda Alonso, Clara; Maghraoui Meherzi, Hager; García-Tecedor, Miguel; Gimenez, Sixto; Julian-Lopez, Beatriz Wiley (2020-04-23)
      Lead sulfide (PbS) nanocubes are produced by a very simple solvothermal procedure that uses a unique molecule, ethylenediamine, as solvent and capping ligand to control the size and shape of the nanocrystals. Detailed ...

    • openAccess   Negative Capacitance and Inverted Hysteresis: Matching Features in Perovskite Solar Cells 

      Alvarez, Agustin; Arcas, Ramón; Aranda Alonso, Clara; Bethencourt, Loengrid; Mas, Elena; Saliba, Michael; Fabregat-Santiago, Francisco American Chemical Society (2020-10-01)
      Negative capacitance in the low-frequency domain and inverted hysteresis are familiar features in perovskite solar cells, which origin is still under discussion. Here we use impedance spectroscopy to analyze these responses ...

    • openAccess   Observation of Long-Term Stable Response in MAPbBr3 Single Crystals Monitored through Displacement Currents under Varying Illumination 

      García-Batlle, Marisé; Zia, Waqas; Aranda Alonso, Clara; Saliba, Michael; Almora Rodríguez, Osbel; Guerrero, Antonio; Garcia-Belmonte, Germà Wiley-VCH GmbH (2022-06-30)
      Long life of perovskite devices in working conditions remains the bottleneck for technology application. Stable charge carriers’ transport together with nonreactive contact materials contributes to the increase of the ...

    • openAccess   On Mott-Schottky analysis interpretation of capacitance measurements in organometal perovskite solar cells 

      Almora Rodríguez, Osbel; Aranda Alonso, Clara; Mas, Elena; Garcia-Belmonte, Germà AIP Publishing (2016)
      Capacitance response of perovskite-based solar cells (PSCs) can be exploited to infer underlying physical mechanisms, both in the materials bulk and at outer interfaces. Particularly interesting is applying the depletion ...
