5N (99.999%) Perovskite Grade Cesium Bromide (CsBr), 10g

5N (99.999%) Perovskite Grade Cesium Bromide (CsBr), 10g

Cesium Bromide (CsBr) is one of the main precursors of CsPbBr₃ all-inorganic halide perovskite materials (ABX₃). Comparing to organic-inorganic halide perovskite materials, all-inorganic halide perovskite materials have better moist resistant and thermal stability. CsPbBr₃ perovskite presents the best weatherability regardless of their large bandgap around 2.3 eV comparing to CsPbI₃, which is the representative of all-inorganic halide perovskite materials. It demonstrates a great potential in semitransparent photovoltaics or high-voltage required electronics owing to the excellent weather resistance and possesses an ultrahigh theoretical open-circuit voltage (V_oc) as well as good light transmittance.
