Application

PI₃ is used in the synthesis of black phosphate crystal, which can be used as a semiconducting material for optoelectronic applications.[1] It is also a source of triiodide that can be utilized as a charge carrier in electrolytes for dye sensitized solar cells.[2][3]

General description

Phosphorus triiodide (PI₃) is a trihalide of phosphorus that can be used as a deactivator and a deoxygenating agent.[4][5]
