• openAccess   Calculation of the Energy Band Diagram of a Photoelectrochemical Water Splitting Cell 

      Cendula, Peter; Tilley, S. David; Gimenez, Sixto; Bisquert, Juan; Schmid, Matthias; Grätzel, Michael; Schumacher, Jürgen O. American Chemical Society (2014-11)
      A physical model is presented for the semiconductor electrode of a photoelectrochemical cell. The model accounts for the potential drop in the Helmholtz layer and thus enables description of both band edge pinning and ...
    • closedAccess   Electron Transport and Recombination in Solid-State Dye Solar Cell with Spiro-OMeTAD as Hole Conductor 

      Fabregat-Santiago, Francisco; Bisquert, Juan; Cevey, Le; Chen, Peter; Wang, Mingkui; Zakeeruddin, Shaik Mohammed; Grätzel, Michael American Chemical Society (2009)
      We show that electron transport mechanisms in TiO2 solid-state dye-sensitized solar cells (SDSCs) with spiro-OMeTAD as hole conductor are similar to those of high-performance DSCs with liquid electrolytes and ionic liquids. ...
    • closedAccess   Understanding the Role of Underlayers and Overlayers in Thin Film Hematite Photoanodes 

      Steier, Ludmila; Herraiz Cardona, Isaac; Fabregat-Santiago, Francisco; Bisquert, Juan; Tilley, S. David; Grätzel, Michael Wiley (2014-12-23)
      Recent research on photoanodes for photoelectrochemical water splitting has introduced the concept of under- and overlayers for the activation of ultrathin hematite films. Their effects on the photocatalytic behavior were ...
