General description
Tin(II) iodide is an orange crystalline solid with a high melting point. It is widely used to fabricate organic–inorganic solar cells, light-emitting devices, and secondary batteries. It acts as a reducing agent.
Application
Tin(II) iodide can be used:
- As a precursor to fabricate methylammonium tin iodide films for heterojunction-depleted perovskite solar cells using solvent-mediated crystallization.
- To prepare highly stable perovskite thin films for Pb-free light-emitting diodes(PeLEDs). and a new air-stable one-dimensional (1D) hybrid lead-free halide material (DAO)Sn2I6 which emits broad orange light at 634 nm and photoluminescence quantum yield of 36%.
- As a dual-functional electrolyte additive in high-rate Li-air batteries. SnI2 protects the lithium anode and reduces charge potential by promoting the decomposition of the Li2O2.
- To synthesize mixed Pb–Sn perovskite films with formamidine sulfinic acid(FSA) for all tandem perovskite solar cells.

This is important to whether I buy your product.I would like to ask whether 409308 and 466352 are products obtained by two different synthetic routes or 466352 was obtained by further purifying 409308. And how do you synthesize and purify Tin(II) iodide?
