Synthetic- Chemical Vapour Transport (CVT)
Tin sulfide (SnS), with a direct energy band-gap of about 1.3 eV, and a high optical absorption coefficient over 5 × 104 cm-1,is a promising new candidate for applications in the next generation of photovoltaic solar cells. Made of earth-abundant, relatively cheap and environmentally-nontoxic elements, SnS is solution processable and stable in both alkaline and acidic conditions.
In the form of single or few-layer thin films,exfoliated SnSnanosheets have various applications.These include light emitters, field effect transistors (FETs), gas sensors, photodetectors, thermoelectric and photovoltaic devices.
Tin sulfide(SnS)is manufactured using chemical vapour transport (CVT) crystallisation, with crystals having a purity in excess of 99.999%.
Dark-gray or black, crystalline powder. Soluble in concentrated
hydrochloric acid (decomposes); insoluble in
dilute acids and water.
The p-type IV-VI semiconductor tin(II) sulfide is of interest for use in optoelectronic devices. SnS is also used as a nontoxic, inexpensive component in heterojunction photovoltaic devices.
Polymerization catalyst.Tin(II) sulfide is used as a polymerization catalyst. It is also used as a friction material. Further, it is used in optoelectronic device as well as a component in heterojunction photovoltaic devices.
