Facile Bulk Synthesis of π-Cubic SnS.

The cubic modification of binary tin sulfide (SnS) has gained significant interest as an earth-abundant, low-toxicity solar absorber material with a band gap close to the optimal value for the conversion of sunlight. We herein report a simple synthesis for the metastable material, which will allow more elaborate characterization methods to be used on this material, and present a full powder refinement of the material along with some preliminary results on the optical and thermal stability properties.
