Abstract:
This study examines the structural, optical, and morphological characteristics of Methylammonium lead halide perovskites (MAPbX3) as potential solar cell candidates. Variable band gaps, extended carrier lifetimes, high absorption coefficients, and solution-processable synthesis techniques are among the numerous advantages of these perovskites. The Hot-Injection Method (HIM) is employed in the study to further investigate the unique properties of MAPbX3 perovskites, which is cost-effective and does not require vacuum. MAPbBr3 and MAPbCl3 crystallize in a cubic phase, whereas MAPbI3 crystallizes

In this paper, thin layers of ZnO were deposited onto fluorine-doped tin oxide (FTO) substrates. Subsequently, different layers of perovskite (MAPbX3, X = I, Br, Cl) were spin-coated onto these ZnO layers. The resulting layers were characterized using X-ray diffraction (XRD), UV-Visible spectroscopy, and scanning electron microscopy (SEM). Special attention was given to the surface topography, the crystallinityand optoelectronic properties.XRD analysis of all the thin layers showed two diffraction peaks for the ZnO/MAPbX3 heterojunction corresponding to the crystallographic planes (100) and (2

Abstract:
Inelastic light scattering spectra of organic–inorganic halide perovskite MAPbCl3 single crystals were investigated by using Brillouin spectroscopy. Sound velocities and acoustic absorption coefficients of longitudinal and transverse acoustic modes propagating along the cubic [100] direction were determined in a wide temperature range. The sound velocities exhibited softening upon cooling in the cubic phase, which was accompanied by the increasing acoustic damping. The obtained relaxation time showed a critical slowing-down behavior, revealing the order–disorder nature of the phase transition,

Abstract:
Hybrid perovskites, especially methylammonium lead iodide (MAPbI3), exhibit excellent solar power conversion efficiencies. However, their application is plagued by poor chemical and structural stability. Using direct calorimetric measurement of heats of formation, MAPbI3 is shown to be thermodynamically unstable with respect to decomposition to lead iodide and methylammonium iodide, even in the absence of ambient air or light or heat-induced defects, thus limiting its long-term use in devices. The formation enthalpy from binary halide components becomes less favorable in the order MAPbCl3, MAP
