Description

Application

Cesium iodide anhydrous can be used as a precursor or component in the synthesis of the perovskite absorber layer in perovskite solar cells. By introducing cesium iodide into the perovskite composition, the bandgap of the material can be tuned to better match the solar spectrum, optimizing the light absorption and energy conversion efficiency of the solar cell.

Cesium iodide finds application in synthesis of perovksites based photovoltaic materials. Our perovskite grade CsI can readily be dissolved in 1:1 vol DMF/DMSO to yield 1M solution.

Features and Benefits

Frequently used in devices such as phosphor screens for medical imaging, scintillators, calorimeters and a variety of particle detectors.

Packaging

Packaged in ampules
