Descripción

General description

Cesium chloride is a highly water soluble crystalline solid withhigh refractive index and dielectric properties. It is widely used in the field of solid oxide fuel cells and lighting devices.[1,2]

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.[1] -As a medium to synthesize N and P-codoped carbon nanospheres for application in fuel cells and zinc-air batteries.[3] -To fabricate silicon nanopillars for solar cells, batteries, light-emitting diodes, etc.[4] -To enhance the thermal stability of polyoxometalates(used as electrode materials for lithium-ion batteries).[2] -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.[5]
