In the recent reports, it is clear that lead-free perovskite materials with low band gaps are desirable candidates for photovoltaic cells. this regard, was observed germanium (Ge) a less toxic metal significant preparation of Ge-based materials. materials, example, methyl ammonium iodide (MAGeI3), cesium (CsGeI3), and/or formamidinium (FAGeI3) may be suitable absorber and alternatives towards fabrication past few years, attempts were made to develop FAGeI3-based solar cells, but their performance still under limitations. This indicating some effective strategies should designed developed construction It believed optimization layer thickness, device structure, selection electron transport (ETL) improve Solar cell capacitance simulation, i.e., SCAPS one promising software programs can provide theoretical findings development The simulation studies via benefit researchers save energy high cost process in laboratories. research article, adopted as tool investigations exhibited excellent efficiency 15.62% SCAPS. study proposed optimized structure FTO/TiO2/FAGeI3/PTAA/Au enhanced performance.

Abstract This study presents a comprehensive analysis of the structural, mechanical, electronic, and optical properties GaXF 3 compounds (where X = Ca Sr), which belong to perovskite halogenide family with gallium as base element. The structural stability GaCaF GaSrF was confirmed through Birch–Murnaghan equation‐of‐state optimization using density functional theory (DFT) implemented in CASTEP. Mechanically, these exhibit notable ductility, scratch resistance, anisotropy, mechanical stability, high resistance plastic deformation. electronic band structures reveal insulating behavior, direct gaps 4.1 eV for 4 at M‐M symmetry points. To further understand interactions between different electron states, total states (TDOS) partial (PDOS) analyses were conducted. wide provide detailed basis studying compounds' properties, showing significant absorption conduction high‐energy spectra, while allowing transparency low‐energy photons. These findings suggest that are promising materials advanced devices energy storage applications, offering foundation future research photocatalysis optoelectronics.
