摘　　要：在钙钛矿太阳电池中,定向生长的TiO_(2)纳米棒阵列具有可控的排列结构,能够为电子的传输提供有序的径向传输通道,从而改善电子在界面间的分离与传输。本文通过水热法成功制备了长度为400 nm、直径为65 nm、面密度为160μ·m^(-2)的锐钛矿相TiO_(2)纳米棒阵列,使用摩尔比n(CH_(3)NH_(3)I):n(CH_(3)NH_(3)Br)=85:15的CH_(3)NH_(3)PbI_(3-x)Br_(x)薄膜作为钙钛矿光吸收层,spiro-OMeTAD作为空穴传输层组装了基于锐钛矿相TiO_(2)纳米棒阵列的钙钛矿太阳电池,研究了不同纳米棒阵列对钙钛矿太阳电池光伏性能的影响,结果表明,基于锐钛矿相TiO_(2)纳米棒阵列钙钛矿太阳电池在相对湿度为54%的空气环境下取得了14.35%的光电转换效率。In perovskite solar cells,directionally grown TiO_(2) nanorod arrays have a controllable and ordered arrangement structure,which can provide ordered radial transmission channels for electron transporting,improving the separation and transmission of electrons in interfaces.The anatase TiO_(2) nanorod array with a length of 400 nm,a diameter of 65 nm,and an areal density of 160μ·m^(-2) was successfully prepared via hydrothermal method.The perovskite solar cell based on the anatase TiO_(2) nanorod array was assembled using the CH_(3)NH_(3)PbI_(3-x)Br_(x) thin film with a molar ratio of n(CH_(3)NH_(3)I):n(CH_(3)NH_(3)Br)=85:15 as the perovskite light absorption layer and spiro-OMeTAD as the hole transporting layer.The effect of different nanorod arrays on the photovoltaic performance of perovskite solar cells was studied,and the results showed that the anatase TiO_(2) nanorod array perovskite solar cell had a photoelectric conversion efficiency of 14.35%at the relative humidity of 54%.
