General description
Cesium chloride is a white crystalline solid that is soluble in water. It is widely used in the field of solar cells and nucleic acid separation. It is partially soluble in ethanol and methanol but highly soluble in formic acid. Cesium chloride has a wide band gap of about 8.35 eV at 80 K.
Application
Cesium chloride can be used:
- As a precursor to fabricate homogeneous perovskite films with high crystallinity and preferential orientation. These films enhance the power conversion efficiency of solar cells.
- To synthesize blue emission lead-free antimony Cesium halide Qdots of high PLQY of 46% and Mn-Doped Cs2Na1–xAgxBiCl6 double perovskites for engineering the band gap and tailoring the energy transfer.
- To fabricate polyoxometalate electrode materials for Li-ion batteries. The addition of CsCl enhances the thermal stability and cycling stability of the battery cell.
- To prepare a density gradient solution for the separation of nucleic acids.
