Abstract
Lead free perovskite materials are attractive due to non-toxicity and the chemical stability. Therefore Tin, Germanium, Bismuth and Antimony are promising alternatives for lead. Among these Bismuth is promising candidate due to it exhibits similar optical and electrical properties of lead. Herein we fabricated lead free Formamidinium Bismuth Iodide FA3Bi2I9 powder by solid state method at room temperature. The perovskite crystal structure is confirmed via XRD analysis. The surface morphology and temperature sustainability of perovskite powder is investigated. The optical studies of perovskite powder are examined and inferred with a wide UV–Visible absorption spectrum from 350 to 600 nm. The band gap and photo emission wavelength for FA3Bi2I9 perovskite powder are found to be 2.46 eV and 643 nm respectively.
