"This work is a theoretical study on the effect of various methods of preparing perovskite on its physical and chemical properties, as well as uses of LaFeO3 in battery charge, solar cell manufacturing, and thermal stimulation, with a particular focus on comparing results with previous articles on LaFeO3. First, we compared results obtained from the sol-gel method and hydrothermal treatment using X-r diffraction (XRD) to assess crystalline structure at 800 °C. On the other hand, the solid state method showed high-grade crystalline structure at 900 °C. Results of weight thermal analysis (TGA) and differential thermal analysis (DTA) indicated active peaks at 800 °C in the sol-gel and hydrothermal method, indicating similar degradation processes. In the solid state method, an active peak is observed at 900 °C. Using FTIR technology, all three methods showed absorption associated with the vibrational patterns of functional groups, with the expansion of the O-H, C-O, and C = O bonds. Our study revealed that sol-gel method is the easiest, most used, and least expensive method, providing the most accurate results
