“…The characteristic peaks of the perovskite (110) and ( 220) are located at 14.0 • and at 28.1 • , respectively. The peaks reported correspond to peaks reported previously [3]. From this analysis, we can say that the three samples show the growth of the material on the substrate.…”

In this work, FAPbI3 thin films with different antisolvents (toluene, diethyl ether and chlorobenzene) were successfully elaborated by the spin coating technique to study the influence of the different antisolvents in the films. The crystal structure, surface morphology and optical properties were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM) photoluminescence and UV–visible spectrometry. According to XRD, the crystalline structure of FAPbI3 was found in the orientation of the (110) plane, and it is observed that the type of antisolvent content in the absorber layer plays an important role in the growth and stabilization of the film. Here, chlorobenzene leads to a smooth and homogenous surface, a large grain size and a pinhole-free perovskite film. Additionally, the optical analysis revealed that the band gap is in the range from 1.55 to 1.57 eV. Furthermore, in an approximately 60% humidity environment and after two weeks, the stability and absorption of FaPbI3 showed low degradation.

“…The stoke shift describes the reduction of lattice parameters in the crystals. The low value of the stoke shift indicates the good photophysical properties of MAPbI 3 (Bouich et al, 2021a;Bouich et al, 2021b).…”

This work reported the successive incorporation of tetrabutylammonium (TBA) into Methylammonium lead Iodide (MAPbI3) perovskite. The thin films were characterized by X-Ray diffraction (XRD), Scanning electron microscopy (SEM), Transmittance electron microscopy (TEM), Atomic force microscopy (AFM), and UV-Visible spectroscopy. It was shown that introducing TBA increases the crystallinity, grain size, surface morphology without pin-hole, and roughness of the MAPbI3 thin films. Moreover, the MA(1-X)TBAX PbI3 thin film shows better stability in a relative humidity of ∼60% after 15 days than the pure MAPbI3 thin film. The obtained results are hoped to be helpful for stability and improvement of the performance of the MAPbI3 thin films by doping TBA cations under ambient conditions.

“…Perovskite materials possess excellent optical and electrical properties, such as a direct bandgap ranging from 1.5 to 2.3 eV and the potential to transport electrons and holes. [ 1–3 ] For manufacturing perovskite thin films with good morphology and high quality, various low‐cost techniques have been used. Among these techniques, spin coating with one‐step process is usually used as it is easy to control and quick to produce.…”

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. However, the content of lead (Pb) in the material may origin a dramatic after effect on human's health caused by its toxicity. Here, we investigate replacing the lead in MAPbI3 with tin (Sn) to show its influence on the growth of the film nucleation and stability of the solar device based on MASnI3. By analysing the manufactured perovskite films by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X‐ray diffraction (XRD), UV–visible absorption, photoluminescence (PL) and atomic force microscopy (AFM), the properties of the thin films when lead is replaced by tin are reported. The simulation run for the case of MAPbI3 is reported, where Voc = 0.856 V, Jsc = 25.65 mA cm−2, FF = 86.09%, and ETA = 18.91%, and for MASnI3, Voc = 0.887 V, Jsc = 14.02 mA cm−2, FF = 83.72%, and ETA = 10.42%. In perovskite‐based devices using MASnI3 as absorber, it was found to be more stable despite of its lower efficiency, which could be improved by enhancing the bandgap alignment of MaSnI3. The results of this paper also allow the development of a new, reliable production system for PSCs.
