摘　　要：采用季铵化反应成功合成了[Bmim]I，并制备了含有[Bmim]I、KI和I2的离子液体液体电解质和凝胶电解质。通过对比[Bmim]I浓度对液体和凝胶电解质电导率的影响及液体、凝胶电解质DSC的各项光电性能，发现液体电解质有更高的电导率，其组装的DSC的光电性能均高于凝胶电解质体系，通过对DSC稳定性的对比，发现离子液体凝胶电解质显示了更好的长期稳定性。1-butyl-3-methylimidazolium Iodide was synthesized by quaternization. The photovoltaic performance of dye-sensitized solar cells （DSC） was compared for electrolytes containing different concentrations of [Bmim]I, KI and iodine. By observing the ionic conductivity, photovoltaic performance and long-term stability of DSC, it is found that the liquid electrolyte has higher ionic conductivity than the gel electrolyte, and shows higher photovoltaic performance than the gel electrolyte, but the DSC with the gel electrolyte shows the more stable than the liquid electrolyte.
