      Due to the high industrial interest for perovskite-based photovoltaic devices, there is an urgent need to fabricate them under ambient atmosphere, not limited to low relative humidity (RH) conditions. The formamidinium ...
    • openAccess   Origin of discrete donor–acceptor pair transitions in 2D Ruddlesden–Popper perovskites 

      Gorji, Setatira; Krecmarova, Marie; Molina-Sánchez, Alejandro; Asensio, Maria C.; Gualdrón Reyes, Andrés Fabián; Rodríguez Romero, Jesús; Pashaei Adl, Hamid; Canet Albiach, Rodolfo Enrique; Schio, Luca; Tormen, Massimo; Floreano, Luca; Mora-Sero, Ivan; Martínez-Pastor, Juan P.; Sánchez Royo, Juan Francisco; Muñoz-Matutano, Guillermo American Institute of Physics (2024)
      Two-dimensional (2D) van der Waals nanomaterials have attracted considerable attention for potential use in photonic and light–matter applications at the nanoscale. Thanks to their excitonic properties, 2D perovskites are ...
    • openAccess   Revealing giant exciton fine-structure splitting in two-dimensional perovskites using van der Waals passivation 

      Canet Albiach, Rodolfo Enrique; Kreĉmarová, Marie; Bosch Bailach, José; Gualdrón Reyes, Andrés Fabián; Rodríguez Romero, Jesús; Gorji, Setatira; Pashaei Adl, Hamid; Mora-Sero, Ivan; Martínez-Pastor, Juan P.; Sánchez Royo, Juan Francisco; Muñoz-Matutano, Guillermo ACS Publications (2022-09-08)
      Organic–inorganic layered perovskites are currently some of the most promising 2D van der Waals materials. Low crystal quality usually broadens the exciton line width, obscuring the fine structure of the exciton in ...
    • openAccess   Solution-Processed Ni-Based Nanocomposite Electrocatalysts: An Approach to Highly Efficient Electrochemical Water Splitting 

      Noguera-Gomez, Jaume; García-Tecedor, Miguel; Sánchez Royo, Juan Francisco; Valencia, Luisa M.; de la Mata, María; Herrera Collado, Miriam; Molina, Sergio I.; Abargues, Rafael; Gimenez, Sixto American Chemical Society (2021-05-10)
      In this study, we report an up-scalable and low-cost solution-processed method to in situ synthesize an earth-abundant non-stoichiometric NiOx-based electrocatalytic film for water oxidation. The catalytic activity was ...
    • 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 ...
