单硫化锡（sn）是一种有前途的吸收材料，用于开发低成本、溶液可加工的太阳能电池。在这里，我们提出了一种简单的，基于溶液的方法来制备单硫化锡（SnS）薄膜，采用绿色溶剂，即四氢呋喃（THF）。我们发现，通过改变前驱体溶液的组成和薄膜的沉积条件，可以调节SnS薄膜的表面覆盖度和形貌。此外，我们探索了PEDOT:PSS中间层的影响，并基于以下结构制备了太阳能电池：FTO/平面- tio2 /介孔- tio2 /SnS/P3HT/PEDOT:PSS/Ag。基于该架构的器件显示出3.0%的功率转换效率（pce），从而证明了我们的方法在开发低成本和环保太阳能电池方面的潜力。
Tin monosulfide (SnS) is emerging as a promising absorber material for the development of low-cost, solution-processable solar cells. Herein, we present a straightforward, solution-based route for the preparation of tin monosulfide (SnS) films employing a green solvent, namely, tetrahydrofuran (THF). We show that the surface coverage and the morphology of the SnS films can be tuned by modification of the precursor solution composition and film deposition conditions. Furthermore, we explore the effect of a PEDOT:PSS interlayer and fabricate solar cells based on the following architecture: FTO/planar-TiO2/mesoporous-TiO2/SnS/P3HT/PEDOT:PSS/Ag. Devices based on this architecture are shown to exhibit power conversion efficiencies (PCEs) of 3.0%, thus demonstrating the potential of our method for the development of low-cost and environmentally friendly solar cells.
