• openAccess   Surface Recombination and Collection Efficiency in Perovskite Solar Cells from Impedance Analysis 

      Zarazúa, Isaac; Han, Guifang; Boix, Pablo P; Mhaisalkar, Subodh; Fabregat-Santiago, Francisco; Mora-Sero, Ivan; Bisquert, Juan; Garcia-Belmonte, Germà American Chemical Society (2016-11)
      The large diffusion lengths recurrently measured in perovskite single crystals and films signal small bulk nonradiative recombination flux and locate the dominant carrier recombination processes at the outer interfaces. ...
    • closedAccess   Theory of Impedance Spectroscopy of Ambipolar Solar Cells with Trap-Mediated Recombination 

      Bertoluzzi, Luca; Boix, Pablo P; Mora-Sero, Ivan; Bisquert, Juan American Chemical Society (2014-01)
      The analysis of recombination in solar cells suggests in many cases the presence of trap-mediated recombination in the absorber. We present a theory of the recombination of electrons and holes, the Shockley–Read–Hall model, ...
    • openAccess   α-FAPbI3 powder presynthesized by microwave irradiation for photovoltaic applications 

      Solis, Omar E.; Fernández-Saiz, Carolina; Rivas Martínez, Jesús Manuel; Esparza, Diego; Turren Cruz, Silver Hamill; Julian-Lopez, Beatriz; Boix, Pablo P; Mora-Sero, Ivan Elsevier (2022-12-10)
      The development of up-scalable and high-throughput methodologies to fabricate high-efficiency lead halide perovskite solar cells (PSCs) based on α-phase formamidinium lead iodide (FAPbI3) is one of the main challenges of ...
