摘要:
有机胺盐表面修饰是钙钛矿太阳能电池中钝化钙钛矿表面缺陷和提升电池稳定性的有效方法。旋涂苯乙基碘化铵(phenylethylammonium iodide,PEAI)和四丁基碘化铵(tetrabutylammonium iodide,TBAI)溶液在CsPbI3钙钛矿薄膜表面并进行热处理,修饰钙钛矿表面,采用X射线衍射仪、扫描电镜、稳态瞬态荧光寿命光谱仪对薄膜的结构形貌和光电性能进行表征分析,通过电流密度电压测试、电化学阻抗测试和暗态电流密度电压测试对比两种表面修饰剂对CsPbI3钙钛矿薄膜和器件性能的影响。结果表明:PEAI不能与CsPbI3发生离子交换生成低维钙钛矿,仅通过吸附在表面钝化缺陷并阻碍水汽侵入,提升薄膜的稳定性;而TBAI可有效进入无机CsPbI3钙钛矿晶格,形成低维钙钛矿相,进而改善薄膜形貌、钝化缺陷并提升薄膜的稳定性;TBAI修饰的电池器件光电转换效率相较于PEAI修饰的器件提升了8.5%,同时器件的稳定性也得到了增强。该研究为开发适用于全无机CsPbI3钙钛矿的新型表面修饰剂提供了指导和方向。
