• closedAccess   Hole Band Mixing in CdS and CdSe Quantum Dots and Quantum Rods 

      Planelles, Josep; Rajadell Viciano, Fernando; Climente, Juan I. American Chemical Society (2010)
      Using a six-band k·p Hamiltonian for wurtzite lattice, we study the hole ground state symmetry and composition in spherical quantum dots and elongated quantum rods made of CdS and CdSe. The ground state crossovers which ...
    • closedAccess   Panchromatic sensitized solar cells based on metal sulfide quantum dots grown directly on nanostructured TiO2 electrodes 

      Mora-Sero, Ivan; Giménez Juliá, Sixto; Braga, Antonio; Concina, Isabella; Vomiero, Alberto American Chemical Society (2011-02)
      The use of narrow band gap semiconductors such as PbS may expand the light absorption range to the near-infrared region in quantum-dot-sensitized solar cells (QDSCs), increasing the generated photocurrent. However, the ...
    • closedAccess   Role of the Selective Contacts in the Performance of Lead Halide Perovskite Solar Cells 

      Juarez-Perez, Emilio J.; Wuβler, Michael; Fabregat-Santiago, Francisco; Lakus Wollny, Kerstin; Mankel, Eric; Mayer, Thomas; Jaegermann, Wolfram; Mora-Sero, Ivan American Chemical Society (2014-01)
      The effect of electron- and hole-selective contacts in the final cell performance of hybrid lead halide perovskite, CH3NH3PbI3, solar cells has been systematically analyzed by impedance spectroscopy. Complete cells with ...
