【摘要】 采用预合成法合成铜铟硫(Cu In S2)量子点并将其应用于介孔太阳电池中。利用紫外可见吸收光谱、XRD和TEM等表征手段深入研究氧化物、硫化物、硒化物等不同包覆层对Cu In S2量子点敏化太阳电池性能的影响。结果表明,硫化物包覆层对Cu In S2量子点敏化太阳电池具有较优的性能,尤其是Cd S包覆,电池短路电流密度为13.6 m A/cm2,光电转换效率达到2.67%。最后探索Cu In S2量子点在有机-无机杂化钙钛矿太阳电池中的应用,其作为空穴传输材料,电池效率可达6.57%。更多还原

【Abstract】 CuInS2 quantum dots were pre-synthesized and applied in mesoporous solar cells. The influence of differentcoating materials such as oxides,sulfides and selenides on the performance of the liquid quantum dot-sensitized solarcells was investigated by UV-visible absorption spectrum,XRD and TEM. The results show that when CuInS2 quantumdots were passivated with Cd S layer,the conversion efficiency of sensitized solar cell reaches 2.67% and the short-circuitcurrent density is 13.6 m A/cm2 under AM1.5 illumination. Moreover,when CuInS2 quantum dots are used as a holetransporting material in organic-inorganic perovskite solar cells,the power conversion efficiency of 6.57% is obtained.更多还原
