Review of inorganic Sb perovskites and their applications

Perovskite (PVK) halides represent versatile materials in both production and application. Given their continuous focus in research, this article aims to provide a comprehensive review of lead-free perovskites based on antimony, characterized by the formula Cs3Sb2X9, with X representing Cl−, I− or Br−. The objective is to present the latest research findings at the time of writing this document, categorized by applications and their corresponding outcomes. Although this compound is predominantly studied in the domain of photovoltaic devices, it is important to acknowledge its relevance in other applications. Therefore, this article also investigates its utilization in other areas such as photocatalysis and light-emitting diodes (LEDs). Key parameters such as crystalline structure and band gap (Eg) are highlighted, given their significance in perovskite characterization. In essence, this work not only serves to disseminate knowledge about these materials but also aims to catalyze further research aimed at enhancing the utilization of lead-free perovskites across various domains.
