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%.

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 %).
