indium Compounds
Indium Sulfide
Indium sulfide (In₂S₃) is a pivotal material in the advancement of sustainable energy solutions. With its vibrant orange-red hue and distinct sulfide odor, this compound plays a crucial role as an eco-friendly alternative to cadmium sulfide in copper-indium-gallium-selenide (CIGS) thin-film solar cells. Apply it with vacuum chemical vapor deposition or DC magnetron sputtering for maximum flexibility in your manufacturing processes.

- Eco-Friendly Alternative to Cadmium Sulfide
- Purity Ranging From 4N (99.99%) to 5N (99.999%)
- High Volume and Reliable Supply
Product Overview
Indium sulfide is recognized for its stability and unique properties. It is insoluble in water and most organic solvents, but decomposes in mineral acids, releasing hydrogen sulfide gas. It is available in both powder and pellet forms, catering to the most stringent requirements of the photovoltaic industry.
Features
Distinct Odor
Indium sulfide emits a foul smell reminiscent of rotten eggs.
Pioneers of Indium
German chemists Ferdinand Reich and Hieronymus Theodor Richter discovered determined the existence of indium as a new element from the sulfide precipitate of indium in 1863.
2.1 eV
B-In2S3 is an N-type semiconductor with an optical band gap of 2.1 eV, making it an alternative to the hazardous CdS.
Colorful Impact
The vivid orange-red color of indium sulfide is visually striking and indicative of its high-energy band gap, which plays a crucial role in solar energy conversion.
