Tin sulfide

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.

What are the applications of 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.

Synthesis

Tin sulfide?(SnS)?is manufactured using chemical vapour transport (CVT) crystallisation, with crystals having a purity in excess of 99.999%.

Preparation

Synthetic?- Chemical Vapour Transport (CVT)

Chemical properties

Dark-gray or black, crystalline powder. Soluble in concentrated hydrochloric acid (decomposes); insoluble in dilute acids and water.

The Uses of Tin sulfide

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.
