摘要:
有机-无机杂化钙钛矿具有高的光吸收系数、可调节的带隙以及双极性的电荷传导特性, 是一种理想的光吸收材料。然而, 溶液法制备的钙钛矿薄膜在表/界面上存在多种缺陷, 会抑制载流子传输并引发复合。本研究选用含多官能团的氨基酸衍生物——9-芴甲氧羰基-L-苯丙氨酸-L-苯丙氨酸(Fmoc-FF-OH)作为添加剂来降低钙钛矿膜缺陷并抑制晶界上的载流子复合。结果表明, 当Fmoc-FF-OH的浓度为0.6 g·L-1时, 钙钛矿薄膜的粒径从138 nm增大到210 nm, 缺陷态密度从2.46×1015 cm-3降低至2.17×1015 cm-3。同时, 钙钛矿太阳能电池也表现出最优的性能, 开路电压从1.05 V提升到1.10 V, 器件的光电转化效率(PCE)从15.50%提升到17.44%。在220 h的稳定性测试中, 器件的光电转化效率仍能维持初始的71%。
