Application
In the form of single or few-layer thin films,?exfoliated SnS?nanosheets have various applications.?These include light emitters, field effect transistors (FETs), gas sensors, photodetectors, thermoelectric and photovoltaic devices.
Description
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.
Preparation
Synthetic?- Chemical Vapour Transport (CVT)
Synthesis
Tin sulfide?(SnS)?is manufactured using chemical vapour transport (CVT) crystallisation, with crystals having a purity in excess of 99.999%.
Chemical Properties
Dark-gray or black, crystalline powder. Soluble in concentrated
hydrochloric acid (decomposes); insoluble in
dilute acids and water.
Uses
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.
Uses
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.
