研究了聚硅烷添加剂对CH_3NH_3PbI_3钙钛矿太阳能电池的影响。采用旋涂法制备了含有聚甲基苯基硅烷、聚苯基硅烷和十苯基环戊硅烷（DPPS）的钙钛矿前驱体溶液，并通过X射线衍射和光学显微镜对其微观结构进行了分析。通过引入这些聚硅烷增加了开路电压，并且通过添加DPPS增加了短路电流密度，这导致光转换效率提高到10.46%。在400~750 nm波长范围内，入射光-电流转换效率也有所提高。微观结构分析表明，形成了致密的界面结构的晶粒生长和增加的表面覆盖的钙钛矿层与DPPS，PbI 2的形成受到抑制，导致光伏性能的改善。
Effects of polysilane additions on CH3NH3PbI3 perovskite solar cells were investigated. Photovoltaic cells were fabricated by a spin-coating method using perovskite precursor solutions with polymethyl phenylsilane, polyphenylsilane, or decaphenyl cyclopentasilane (DPPS), and the microstructures were examined by X-ray diffraction and optical microscopy. Open-circuit voltages were increased by introducing these polysilanes, and short-circuit current density was increased by the DPPS addition, which resulted in the improvement of the photoconversion efficiencies to 10.46%. The incident photon-to-current conversion efficiencies were also increased in the range of 400~750 nm. Microstructure analysis indicated the formation of a dense interfacial structure by grain growth and increase of surface coverage of the perovskite layer with DPPS, and the formation of PbI2 was suppressed, leading to the improvement of photovoltaic properties.
