      Valdés, Matías; Sánchez González, Yudania; Fonoll Rubio, Robert; Placidi, Marcel Jose; Izquierdo Roca, Víctor; Cabas Vidani, Antonio; Mittiga, Alberto; Pistor, Paul; Malerba, Claudia; Saucedo Silva, Edgardo Ademar (2022-10-01)
      Article
      Open Access
      The addition of alkali elements has become mandatory for boosting solar cell performance in chalcogenide thin films based on kesterites (Cu2ZnSnS4, CZTS). A novel doping process is presented here, that consists in the ...
    • Epoxy-silica/clay nanocomposite for silver-based antibacterial thin coatings: structure and ionic mobility 

      Giraldo Mejía, Hugo Fernando; Jiménez Piqué, Emilio; Valdés, Matías; Procaccini, Raúl; Pellice, Sergio (2020-07-28)
      Article
      Open Access
      A novel material was developed using sol-gel chemistry and an environmental-friendly grafting process of clay nanoparticles. In a previous work of our group, highly compact coatings had been generated using silicon alkoxides, ...
    • Kinetics and phase analysis of kesterite compounds: Influence of chalcogen availability in the reaction pathway 

      Hernández Martínez, Alejandro; Giraldo, Sergio; Alcobe, Xavier; Becerril Romero, Ignacio; Placidi, Marcel Jose; Izquierdo Roca, Víctor; Pistor, Paul; Perez Rodriguez, Alejandro; Saucedo Silva, Edgardo Ademar; Valdés, Matías (2022-08-01)
