中文摘要：

以碘化铯，碘化亚锡和二氟化锡为原料，采用固相烧结法制备固态电解质CsSnI3-xFx，并测试了相应的染料敏化太阳能电池性能。主要研究了F-掺杂取代I-和SnF2负载量等对电池性能的影响。测试分析了电池的光电流和光电压曲线（I—V曲线）、电化学阻抗谱（EIS）、单色光光子-电子转换效率（IPCE）。实验结果表明，当配比为CsSnI2.95F0.05外添加5％质量分数的SnF2后在450℃下烧成所得的固态电解质电池的性能最优，Cs、Sn、I和F元素在TiO2光阳极分布均匀，电池光电转换效率为5．18％，比液态电解质的效率（7．80％）低33．58％。

英文摘要：

CsSnI3-xFx solid electrolyte was prepared via solid sintering method using cesium iodide stannous iodide and tin bifluoride as raw materials. The influence of doping of CsSnI3 with F and SnF2 on the performance of solar cell was studied. The light voltage curve （I-V Curve）, electrochemical impedance spectroscopy （EIS） and incident photon-to-current conversion efficiency （IPCE） were used to characterize the performance of the solar cells. The study shows that Cs, Sn, I, and F were evenly distributed within the photoanode. At an optimum molar concentration of 5.00% F and 5.00% SnF2, the cell exhibits the highest efficiency. The photoelectric conversion efficiency was 5.18 %, which was 33.58 % lower than that of liquid electrolyte （7.80 %）.
