Abstract Thin-films and nanomaterials with asymmetrical centers are widely used, and a representative example is cubic tin sulfide. The cubic phase of SnS is a “thermodynamic metastable” polymorph of SnS that has not been investigated extensively, unlike the orthorhombic phase. We report a substrate-specific differential growth attribute of π-SnS based on the chemical deposition route. We evaluated the optical properties and band structure of π-SnS and achieved an efficiency of ∼0.12% for a preliminary thin-film solar cell device.

用于薄膜太阳能电池应用的 π-SnS 能带结构的差异生长和评估

摘要 具有不对称中心的薄膜和纳米材料被广泛应用，具有代表性的例子是立方硫化锡。与正交相不同，SnS 的立方相是 SnS 的“热力学亚稳态”多晶型物，尚未得到广泛研究。我们报告了基于化学沉积路线的 π-SnS 的基板特定差异生长属性。我们评估了 π-SnS 的光学特性和能带结构，并获得了约 0.12% 的初步薄膜太阳能电池装置的效率。
