General description
Cesium acetate is a crystalline compound that dissolves moderately well in water and breaks down into cesium oxide when heated. It serves as a useful precursor in the synthesis of high-purity materials, catalysts, and nanomaterials, particularly in advanced chemical and materials research.
Application
Cesium acetate is used
- As an additive in the PbI₂ precursor to enhance perovskite solar cell performance by improving film morphology, and increasing both efficiency and air stability.
- In the synthesis of CsPbX₃@SiO₂ quantum dots, enabling high crystallinity and luminescence for use in white light-emitting diode devices.
- To modify the TiO₂/perovskite interface in all-inorganic perovskite solar cells, for high power conversion efficiency in carbon-based devices.
Features and Benefits
- We offer materials with ≥99.99% purity on a trace metals, ensuring optimal performance. Low impurities in precursors minimize defects in the crystal structure of the synthesized material, enhancing performance and stability.
- Cesium acetate with ≥99.99% purity is crucial for optimal solar cell performance, as impurities can harm carrier recombination, charge transport, and overall device stability. In perovskite and organic solar cells, while additives enhance film morphology and stability, impurities can disrupt these benefits.
- Analyzing 32 elements at ppm levels especially heavy metals such as lead, Cadmium, Arsenic etc. ensure performance.

Lead halide perovskite nanocrystals (NCs) are promising optical materials in many fields. However, their poor moisture stability, significant toxicity, and difficulty to be further functionalized greatly hinder their applications in bioimaging. Here, a universal strategy is demonstrated by simply encapsulating
