    • openAccess   Ionic Field Screening in MAPbBr3 Crystals Revealed from Remnant Sensitivity in X-ray Detection 

      Alvarez, Agustin; Lédée, Ferdinand; García-Batlle, Marisé; López Varo, Pilar; Gros-Daillon, Eric; Mayén Guillén, Javier; Verilhac, Jean-Marie; Lemercier, Thibault; Zaccaro, Julien; Marsal, Lluis F.; Garcia-Belmonte, Germà; Almora Rodríguez, Osbel American Chemical Society (2023-05-03)
      Research on metal halide perovskites as absorbers for X-ray detection is an attractive subject due to the optimal optoelectronic properties of these materials for high-sensitivity applications. However, the contact degradation ...

    • openAccess   Long-term field screening by mobile ions in thick metal halide perovskites: understanding saturation currents 

      Almora Rodríguez, Osbel; Miravet, Daniel; Gelmetti, Ilario; Garcia-Belmonte, Germà Wiley (2022-09-06)
      Metal halide perovskite-based semiconductor devices with micrometer-to-millimeter-thick perovskite layers show a current response upon polarization which evolves up to several hours, transiting several regimes. This is the ...

    • openAccess   Tin perovskite solar cells with >1,300 h of operational stability in N2 through a synergistic chemical engineering approach 

      Sanchez-Diaz, Jesus; S. Sánchez, Rafael; Masi, Sofia; Kreĉmarová, Marie; Álvarez, Agustín O.; Barea, Eva M; Rodriguez-Romero, Jesús; Chirvony, Vladimir; Sánchez Royo, Juan Francisco; Martínez-Pastor, Juan P.; Mora-Sero, Ivan Elsevier (2022-03-14)
      Despite the promising properties of tin-based halide perovskites, one clear limitation is the fast Sn+2 oxidation. Consequently, the preparation of long-lasting devices remains challenging. Here, we report a chemical ...
