Usage

Description

Tin (II) sulfide (SnS) is a p-type IV-VI semiconductor with a direct energy band-gap of about 1.3 eV and a high optical absorption coefficient over 5 × 10^4 cm^-1. It is a promising new candidate for applications in the next generation of photovoltaic solar cells. Made of earth-abundant, relatively cheap, and environmentally non-toxic elements, SnS is solution processable and stable in both alkaline and acidic conditions. It is a dark-gray or black crystalline powder that is soluble in concentrated hydrochloric acid (decomposes) and insoluble in dilute acids and water.

Uses

Used in Optoelectronic Devices:
Tin (II) sulfide is used as a component in optoelectronic devices due to its high optical absorption coefficient and direct energy band-gap.
Used in Heterojunction Photovoltaic Devices:
SnS is used as a nontoxic, inexpensive component in heterojunction photovoltaic devices, making it a suitable material for solar energy applications.
Used in Polymerization Catalysts:
Tin (II) sulfide is used as a polymerization catalyst, playing a crucial role in the synthesis of various polymers.
Used in Friction Materials:
SnS is also used as a component in friction materials, contributing to the development of materials with improved wear resistance and performance.
Used in Thin Film Applications:
In the form of single or few-layer thin films, exfoliated SnS nanosheets have various applications, including light emitters, field effect transistors (FETs), gas sensors, photodetectors, thermoelectric, and photovoltaic devices.
