    • closedAccess   Equivalent Circuit of Electrons and Holes in Thin Semiconductor Films for Photoelectrochemical Water Splitting Applications 

      Bertoluzzi, Luca; Bisquert, Juan American Chemical Society (2012)
      A simple model for the kinetics of electrons and holes in a thin semiconductor film in photoelectrochemical water splitting conditions is discussed, with a focus to discriminate between trap-assisted recombination and ...

    • openAccess   Impact of Oxygen Vacancy Occupancy on Charge Carrier Dynamics in BiVO4 Photoanodes 

      Selim, Shababa; Pastor , Ernest; García-Tecedor, Miguel; Morris, Madeleine; Francàs Forcada, Laia; Sachs, Michael; Moss, Benjamin; Corby, Sacha; Mesa, Camilo A.; Gimenez, Sixto; Kafizas, Andreas; Bakulin, Artem; Durrant, James American Chemical Society (2019-11-27)
      Oxygen vacancies are ubiquitous in metal oxides and critical to performance, yet the impact of these states upon charge carrier dynamics important for photoelectrochemical and photocatalytic applications remains contentious ...

    • 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 ...

    • closedAccess   Relaxation of Electron Carriers in the Density of States of Nanocrystalline TiO2 

      Bertoluzzi, Luca; Herraiz Cardona, Isaac; Gottesman, Ronen; Zaban, Arie; Bisquert, Juan American Chemical Society (2014-01)
      Band gap localized states and surface states play a dominant role in the application of nanocrystalline metal oxides to photovoltaics and solar fuel production. Electrons injected in nanocrystalline TiO2 by voltage or ...
