General description
Cesium(Cs) is a highly reactive alkali metal known for its unique properties its uniqueproperties, such as a low melting point and high atomic mass, which enhance itsexceptional conductivity and reactivity. Its compounds, particularly cesiumlead halide perovskites, are extensively utilized in next-generation solarcells to achieve high efficiency and stability. Additionally, cesium isutilized in electron emission devices and photonic technologies.
Application
- Cesium-containing triple cation perovskite solar cells: improved stability, reproducibility and high efficiency: Demonstrates how adding cesium to perovskite solar cells improves their stability and efficiency, making a significant advancement in solar technology (M Saliba et al., 2016).
- Exotic stable cesium polynitrides at high pressure: Explores the formation of new cesium polynitrides under high pressure, indicating potential applications in high-energy-density materials (F Peng et al., 2015).
