General description

Cesium chloride is a highly water soluble crystalline solid withhigh refractive index and dielectric properties. It is widely used in the fieldof solid oxide fuel cells and lighting devices.

Application

Cesium chloride can be used:
  • As crystal seeds to enhance the coverage of the CH3NH3PbI3−xClx absorber layer in perovskite solar cells. It helps to boost the power conversion efficiency of solar cells.
  • As a medium to synthesize N and P-codoped carbon nanospheres for application in fuel cells and zinc-air batteries.
  • To fabricate silicon nanopillars for solar cells, batteries, light-emitting diodes, etc.
  • To enhance the thermal stability of polyoxometalates(used as electrode materials for lithium-ion batteries).
  • To synthesize the lead-free halide double perovskite Cs2AgInCl6 with excellent moisture, light, and heat resistance. This material shows great potential for various optoelectronic applications, including photovoltaics.
