Tin(II) sulfide crystal, high purity semiconducting material

For applications in next generation photovoltaic solar cells


Tin(II) 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. 

Like the other family members of layered group IV monochalcogenides (including SnSe, GeS, and GeSe), 2D layered SnS has puckered structures - similar to those of black phosphorus. SnS crystallises in the form of an orthorhombic structure, where each Sn(II) atom is coordinated to six S atoms - with three short Sn–S bonds within the surface and three longer Sn-S bonds connecting outer surface of the same layer.

As an analogue to phosphorene, 2D SnS has also been predicted to have strong in-plane anisotropy. However, with two elements of different electronegativity (compared to phosphorene with its single element), the symmetry of SnS structure is rendered, leading to even richer physical properties.
