• openAccess   Flash infrared annealing as a cost-effective and low environmental impact processing method for planar perovskite solar cells 

      Sanchez, Sandy; Vallés Pelarda, Marta; Alberola-Borràs, Jaume-Adrià; Vidal, Rosario; Jerónimo Rendón, José J.; Saliba, Michael; Boix, Pablo P; Mora-Sero, Ivan Elsevier (2019)
      For successful commercialization of perovskite solar cells, straightforward solutions in terms of environmental impact and economic feasibility are still required. Flash Infrared Annealing (FIRA) is a rapid method to ...
    • closedAccess   Perovskite Solar Cell Modeling Using Light- and Voltage-Modulated Techniques 

      Ravishankar, Sandheep; Aranda Alonso, Clara; Sanchez, Sandy; Bisquert, Juan; Saliba, Michael; Garcia-Belmonte, Germà American Chemical Society (2019-02-27)
      The analysis of the impedance spectroscopy (IS) data of perovskite solar cells (PSCs) has been challenging so far, with the low-frequency phenomena in particular yielding ambivalent results and interpretations. We tackle ...
    • openAccess   Thermodynamic stability screening of IR-photonic processed multication halide perovskite thin films 

      Sanchez, Sandy; Carlsen, Brian; Škorjanc, Viktor; Flores-Díaz, Natalie; Serafini, Patricio; Mora-Sero, Ivan; Schouwink, Pascal; Zakeeruddin, Shaik Mohammed; Graetzel, Michel; Hagfeldt, Anders Royal Society of Chemistry (2021-11-24)
      We report a material screening study for phase transitions of multication hybrid halide perovskite films. Two hundred sixty-six films processed with flash infrared annealing were optically and structurally characterized. This ...
