首次在柔性铅箔上原位制备了牡丹花状硫化铅薄膜。以乙二胺为溶剂时，可大规模均匀合成出牡丹花状的硫化铅晶体。通过改变乙二胺与乙醇的体积比，得到了立方、棒状和花状形貌的硫化铅薄膜。研究表明，乙二胺在PbS牡丹花状薄膜的形成过程中起到了关键作用。具有三维微结构的牡丹花状薄膜具有良好的上级吸光性能，在太阳能电池中具有潜在的应用前景。
Peony-like lead sulfide films were in situ fabricated on flexible lead foils for the first time. When only ethylenediamine was used as solvent, peony-like lead sulfide crystals were synthesized uniformly on a large scale. By changing the volume ratio of ethylenediamine to ethanol, lead sulfide films with cube-, rod- and flower-like morphologies were also obtained. Detail study indicated that ethylenediamine played a key role in the formation of the peony-like PbS films. The peony-like films with three-dimensional microstructures exhibited superior absorbance properties and might have potential applications in solar cells.
