Indium Sulfide (In2S3)
Indium Sulfide (In2S3) is used commonly as a buffer layer in thin film solar cells. In2S3 is primarily used as a buffer layer in copper-indium-gallium-diselenide (CIGS) photovoltaic solar cells, replacing toxic cadmium sulfide. This material can be deposited by evaporation or sputtering to form a thin (~1000Å) coating to separate the active material layer from the transparent conductive oxide (TCO) layer.
Indium Corporation offers Indium Sulfide in powder or pellet form.
- Indium Sulfide powder is offered in 4N (99.99%) and 5N (99.999%) purity levels.
- Indium Corporation also produces In2S3 pellets for thermal evaporation processes. These pellets are produced using the same high quality materials as the raw In2S3 powder.

Here’s an interesting technology fact I just learned: Indium Sulfide was the very first indium compound to be discovered. I bet Reich and Richter (the discovers of indium) never imagined that smelly little compound would be used build solar modules and provide electricity. img alt="" src="//cdn2.content.compendiumblog.com/uploads/user/af12973f-cd7e-4c45-9491-c37a7fb2af13/f257d3c4-c185-4407-a4e9-16920aaabcb7/Image/632527810d9659bfd85c7155f6fa9776/cigs_sem_cross_section.jpg" style="border-width: 5px; border-style:...
