    • openAccess   Ionic Dipolar Switching Hinders Charge Collection in Perovskite Solar Cells with Normal and Inverted Hysteresis 

      Almora Rodríguez, Osbel; López Varo, Pilar; Taek Cho, Kyung; Aghazada, Sadig; Meng, Wei; Hou, Yi; Echeverría-Arrondo, Carlos; Zimmermann, Iwan; Matt, Gebhard J.; Jiménez Tejada, Juan Antonio; Brabec, Christoph J.; Nazeeruddin, Mohammad Khaja; Garcia-Belmonte, Germà Elsevier (2019-06-15)
      Drift-diffusion modeling of the ionic dipole switching from the measurement of fast scanned and long pre-biased electrical response is proposed as a novel protocol for evaluation of limit hysteretic effects in perovskite ...

    • openAccess   Light intensity modulated impedance spectroscopy (LIMIS) in all-solid-state solar cells at open-circuit 

      Almora Rodríguez, Osbel; Zhao, Yicheng; Du, Xiaoyan; Heumueller, Thomas; Matt, Gebhard Josed; Garcia-Belmonte, Germà; Brabec, Christoph J. Elsevier (2020)
      Potentiostatic impedance spectroscopy (IS) is a well-established characterization technique for elucidating the electric resistivity and capacitive features of materials and devices. For solar cells, by applying a small ...
