Investigation of Sr(Al₀.₅Nb₀.₅)O₃ Perovskite: A Promising Absorber Layer for High-Efficiency Solar Cells
Sr(Al₀.₅Nb₀.₅)O₃ perovskite was synthesized via the solid-state reaction method and characterized to evaluate its suitability for solar cell applications. X-ray diffraction (XRD) analysis confirmed a well-crystallized cubic perovskite phase with an average lattice constant of 4.3810 Å. Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) revealed a nanostructured morphology with an average particle size of 33.54 nm, confirming the material’s high purity. Fourier Transform Infrared Spectroscopy (FTIR) identified characteristic metal-oxygen vibrational modes, ensuring proper perovskite phase formation. UV-Vis spectroscopy and Tauc plot analysis determined a direct bandgap of 1.54 eV and an indirect bandgap of 1.44 eV, making it a promising candidate for single-junction and tandem solar cells. The lead-free composition, strong UV absorption, and thermal stability of Sr(Al₀.₅Nb₀.₅)O₃ make it a potential material for next-generation photovoltaic applications.
