CESIUM LEAD TRIIODIDE CsPbI₃ 99% CAS 18041-25-3

RESEARCH GRADE MATERIAL

Product Overview

Cesium Lead Triiodide (CsPbI₃, CAS 18041-25-3) is a core all-inorganic perovskite material with CsPbI₃ 99% purity powder, supplied as a white powder with a molecular weight of 720.82 g/mol. As a fully inorganic perovskite precursor, CsPbI₃ exhibits superior thermal stability compared to organic-inorganic hybrid perovskite materials, making it the preferred active layer for all-inorganic perovskite solar cell research targeting high-temperature operational stability. The material is extensively utilized in the development of thermally stable photovoltaic devices, photodetectors, and luminescent nanocrystals. Compatible with solution spin-coating and thermal deposition thin-film fabrication processes, this high-purity precursor delivers consistent optoelectronic performance. Due to its hygroscopic nature, the product requires strict light-sensitive hygroscopic dry storage—sealed under inert atmosphere, protected from light, and maintained at room temperature.

Key Features & Advantages

Superior Thermal Stability of All-Inorganic Composition: Unlike organic-inorganic hybrid perovskites that degrade at elevated temperatures due to volatile organic cation loss, CsPbI₃ exhibits significantly enhanced thermal stability, making it the material of choice for high-temperature photovoltaic and optoelectronic device research.
Ultra-High Purity Exceeding 99%: The cesium lead triiodide is refined to >99% purity with low batch impurity content, minimizing extrinsic defects in inorganic perovskite thin films and supporting reproducible device performance across solution and vapor-phase deposition techniques.
Versatile Application from Thin Films to Nanocrystals: Suitable for CsPbI₃ thin film fabrication via spin-coating and thermal deposition, as well as serving as the precursor for colloidal CsPbI₃ quantum dot and nanocrystal synthesis for light-emitting applications.
Defined Stoichiometry for Reproducible Synthesis: With a molecular weight of 720.82 g/mol, the pre-synthesized CsPbI₃ powder provides precise stoichiometric control, eliminating the need for in-situ multi-precursor ratio optimization in single-source deposition workflows.

APPLICATION SCOPE: Core active layer material for all-inorganic CsPbI₃ perovskite solar cells targeting high-temperature operational stability. Precursor for thermally stable photodetectors and X-ray detectors. Source material for CsPbI₃ colloidal quantum dot and luminescent nanocrystal synthesis. Compatible with single-source thermal evaporation and solution-based spin-coating deposition protocols. Supports research on inorganic perovskite phase stabilization strategies including strain engineering and compositional tuning in university and research institute laboratories.

PACKAGING: This listing is for the 5 g specification. Other packaging weights are available upon custom request. Each package is sealed under inert atmosphere within light-protective packaging to prevent photodegradation and moisture ingress. The hygroscopic nature of cesium lead triiodide necessitates immediate transfer to a desiccated, light-protected storage environment upon receipt. For bulk quantities or custom packaging specifications, please contact us via email.

IMPORTANT NOTICE: Cesium lead triiodide is hygroscopic and light-sensitive. Tighten the container cap immediately after each use to prevent moisture ingress from ambient air. Wear protective gloves throughout all experimental procedures to avoid direct skin contact. Store in a light-protected, moisture-free environment; do not store together with strong oxidizing agents or acidic reagents. Exposure to atmospheric moisture will cause degradation and irreversible alteration of material stoichiometry. When handling the powder, operate within an inert-atmosphere glovebox (H₂O < 1 ppm, O₂ < 1 ppm). This product contains lead; all experimental waste must be disposed of in accordance with heavy metal hazardous waste regulations. For detailed safety and handling information, consult the Safety Data Sheet prior to use.
