INDIUM(III) SULFIDE Usage And Synthesis
General Description
Indium sulfide (In2S3) is an orange-red to red colored powder with the sulfuric odor that is characteristic to all sulfides. It is insoluble in water and most organic solvents but decomposes in common mineral acids, releasing hydrogen sulfide gas.
Indium sulfide is primarily used as a buffer layer in copper-indium-gallium-diselenide (CIGS) photovoltaic solar cells, where it replaces the toxic material cadmium sulfide. Indium sulfide is available in 4N and 5N degrees of purity, and as a powder or compressed pellets.
Chemical Properties
-200 mesh with 99.999% purity; orange powder(s); preparation is by heating In and S or by precipitating with H2S from weakly acidic solutions [KIR81] [STR93] [CER91]
Uses
Indium(III) sulfide emerged as a promising low-hazard buffer material and is used to improve the properties of solar cells and also replaces the hazardous CdS. It is a mid band gap semiconductor.
General Description
Indium sulfide is a mid band gap semiconductor.
