Abstract

Inorganic perovskites (CsPbX₃, X = I⁻, Br⁻ or Cl⁻) have got researchers attention in the photovoltaic community due to their exceptional photoelectric properties and high thermal stability. In this work, we have explained a two-step vapor deposition approach to fabricate the CsPbCl₃ films. To improve the properties of CsPbCl₃ perovskite, different reaction conditions and their influence on the structural, morphological and optical properties of resultant films were systematically examined. We found that the proposed deposition strategy has a wide reaction window and is viable for the preparation of uniform CsPbCl₃ films. The optimal reaction conditions resulted in improved crystallinity, morphology and photoluminescence. The present work will provide beneficial guidance for high-quality CsPbCl₃ and other CsPbX₃ perovskite films for future optoelectronic applications.
