• openAccess   An Equivalent Circuit for Perovskite Solar Cell Bridging Sensitized to Thin Film Architectures 

      Yoo, So-Min; YOON, SEOG JOON; Anta, Juan A.; Lee, Hyo Joong; Boix, Pablo P; Mora-Sero, Ivan Elsevier (2019-08-15)
      Fundamental working mechanisms of perovskite solar cells (PSCs) remain an elusive topic of research. Impedance spectroscopy (IS) has been key to characterizing photovoltaic devices; however, its application to PSCs has ...
    • openAccess   Effects of Frequency Dependence of the External Quantum Efficiency of Perovskite Solar Cells 

      Ravishankar, Sandheep; Aranda Alonso, Clara; Boix, Pablo P; Anta, Juan A.; Bisquert, Juan; Garcia-Belmonte, Germà American Chemical Society (2018-05)
      Perovskite solar cells are known to show very long response time scales, on the order of milliseconds to seconds. This generates considerable doubt over the validity of the measured external quantum efficiency (EQE) and ...
