Abstract

In this work, BaSr(Al₀.₅Nb₀.₅)O₃ (BSAN) perovskite nanoparticles were synthesized using the solid-state reaction method and evaluated for potential application in solar cells. XRD confirmed the formation of a single-phase cubic perovskite structure with crystallite sizes between 33 nm and 55 nm. FTIR analysis indicated characteristic metal–oxygen vibrations, confirming phase formation. SEM analysis revealed uniform, granular nanoparticles with sizes predominantly in the 30–70 nm range. BET surface area analysis exhibited a high specific surface area of 58.4 m²/g and mesoporosity. EDS confirmed elemental homogeneity without impurities. UV-Vis spectroscopy showed strong visible light absorption with an optical bandgap of 1.56 eV, suitable for efficient solar energy harvesting. The combined results highlight BSAN’s suitability as an absorber layer or electron transport layer in photovoltaic devices.
