SnS is a promising candidate as PV absorber material according to the material properties and the Loferski diagram, but despite the numerous publications on this material, the intrinsic material properties are widely unknown and the theoretical possible values for efficiency are still far away from those achieved in reality. Due to the fact that this material is mostly grown as thin film material, bulk research is rare. The material synthesis and the melt growth of tin monosulfide (SnS) by using Bridgman‐Stockbarger technique have been investigated in this study. After first growth experiments produced polycrystalline SnS, a significant reduction of the growth velocity lead to samples with a high amount of single crystalline material. These samples were investigated in detail regarding the structural and optical properties by using XRD/HRXRD, chemical etching and photoluminescence.
