• openAccess   Efficient passivated phthalocyanine-quantum dot solar cells 

      Blas Ferrando, Vicente M.; Ortiz, Javier; González Pedro, Victoria; S. Sánchez, Rafael; Mora-Sero, Ivan; Fernández Lázaro, Fernando; Sastre Santos, Ángela Royal Society of Chemistry (2014-12-08)
      The power conversion efficiency of CdSe and CdS quantum dot sensitized solar cells is enhanced by passivation with asymmetrically substituted phthalocyanines. The introduction of the phthalocyanine dye increases the ...
    • closedAccess   Impedance Spectroscopy Analysis of the Effect of TiO2 Blocking Layers on the Efficiency of Dye Sensitized Solar Cells 

      Góes, Márcio Sousa; Joanni, Ednan; Muniz, Elaine C.; Savu, Raluca; Habeck, Thomas R.; Bueno, Paulo R.; Fabregat-Santiago, Francisco American Chemical Society (2012)
      The introduction of a dense TiO2 layer between the mesoporous TiO2 network and the charge collector in dye-sensitized solar cell anodes has been claimed to improve the performance of solar cell devices. Two mechanisms have ...
    • openAccess   Photoelectrochemical and Impedance Spectroscopic Investigation of Water Oxidation with “Co–Pi”-Coated Hematite Electrodes 

      Klahr, Benjamin; Gimenez, Sixto; Fabregat-Santiago, Francisco; Bisquert, Juan; Hamann, Thomas American Chemical Society (2012)
      Uniform thin films of hematite (α-Fe2O3) deposited by atomic layer deposition (ALD) coated with varying amounts of the cobalt phosphate catalyst, “Co–Pi,” were investigated with steady-state and transient photoelectrochemical ...
    • openAccess   Ru-based nanoparticles supported on carbon nanotubes for electrocatalytic hydrogen evolution: structural and electronic effects 

      Romero, Núria; Fenoll, Dídac A.; Gil Jiménez, Laia; Campos Jara, Sergi; Creus, Jordi; Martí Balaguer, Gerard; Heras-Domingo, Javier; Collière, Vincent; Mesa, Camilo A.; Gimenez, Sixto; Francàs Forcada, Laia; Rodriguez-Santiago, Luís; Solans Monfort, Xavier; Sodupe, Mariona; Bofill, Roger; PHILIPPOT, Karine; García-Antón, Jordi; Sala, Xavier Royal Society of Chemistry (2023-10-10)
      The performance of Ru-based nanoparticles (NPs) in the hydrogen evolution reaction (HER) relies on both their structural properties and the oxidation state of the metal. Herein, the versatility of the organometallic approach ...
