Effect of Deposition Cycles on the Properties of ZnO Thin Films Deposited by Spin Coating Method for CZTS-based Solar Cells

Aamir Shafi, Muhammad; Bouich, Amal; Fradi, Khawla; Marí-Guaita, Julia; Khan, Laiq; Marí, B. (Elsevier, 2022-05)

[EN] The spin-coating technique was used to make ZnO thin films in this study. To get various thicknesses of ZnO thin film on FTO substrate, the numbers of spin coatings were changed, 2,4,6,8, and 10 times. The polycrystalline ...
Insight into the effect of halogen X in methylammonium lead halide (MAPbX3) spin-coated on zinc oxide film

Kone, Klegayere Emmanuel; Bouich, Amal; Marí-Guaita, Julia; Marí, B.; Soro, Donafologo (Elsevier, 2023-01)

[EN] Herein, we investigated the effect of halogen X in methylammonium lead halide (MAPbX3) where X = (Iodide/ Bromide, or Chloride) deposited by spin coating technique on a zinc oxide layer. The ZnO films were first ...
Investigation of the Surface Coating, Humidity Degradation, and Recovery of Perovskite Film Phase for Solar-Cell Applications

Bouich, Amal; Marí-Guaita, Julia; Baig, Faisal; Khattak, Yousaf Hameed; Marí, B.; Palacios, Pablo (MDPI AG, 2022-09)

[EN] Presently, we inquire about the organic/inorganic cation effect on different properties based on structure, morphology, and steadiness in preparing a one-step solution of APbI(3) thin films, where A = MA, FA, Cs, using ...
Investigation on the stability and efficiency of MAPbI3 and MASnI3 thin films for Solar Cells

Marí-Guaita, Julia; Bouich, Amal; Shafi, Muhammad Aamir; Bouich, Asmaa; Marí, B. (John Wiley & Sons, 2022-03)

[EN] Hybrid organic-inorganic halides are considered as outstanding materials when used as the absorber layer in perovskite solar cells (PSCs) because of its efficiency, relieve of fabrication and low-cost materials. ...
Lattice dynamics study of (Gd1-xYbx)(2)O-3(x=0.11) at high pressure

Marí-Guaita, Julia; Gallego-Parra, Samuel; Sans-Tresserras, Juan Ángel; Velázquez, M.; Veber, Phillipe; Rodríguez-Hernández, P.; Manjón, Francisco-Javier; Muñoz, A. (Elsevier, 2021-08-05)

[EN] In this study, we report an experimental investigation of (Gd1-xYbx)(2)O-3 under high pressure by means of Raman scattering measurements complemented with ab initio calculations in pure Gd2O3. Raman spec-troscopy of ...
Manufacture of High-Efficiency and Stable Lead-Free Solar Cells through Antisolvent Quenching Engineering

Bouich, Amal; Marí-Guaita, Julia; Marí, B.; Palacios, Pablo (MDPI AG, 2022-09)

[EN] Antisolvent quenching has shown to significantly enhance several perovskite films used in solar cells; however, no studies have been conducted on its impact on MASnI(3). Here, we investigated the role that different ...
