中文摘要：

研究了一种新型的有机/无机杂化钙钛矿材料（3-BrC3H6NH3）2CuBr4薄膜的聚集态形貌和良好的微观有序性特征,霍尔迁移率测试结果表明该材料为p型半导体,空穴迁移率为0.0025 cm2·V-1·s-1.利用其在紫外-可见光谱范围内与C60薄膜具有良好的光吸收互补性,制备并研究了（3-BrC3H6NH3）2CuBr4/C60层状异质结结构中的暗态传输和光伏性能.对不同退火温度下杂化钙钛矿薄膜的聚集态特性和器件性能之间的联系进行了探讨,结果表明在低温退火条件下,由于钙钛矿结构材料中有机组分排列更加有序,器件显示更好的性能.

英文摘要：

Aggregation morphology and microscopic ordered characteristics of a novel organic-inorganic hybrid material（3-BrC3H6NH3）2CuBr4 thin-film with perovskite structure were studied.Hall mobility test showed that the perovskite was p-type semiconductor with a hole mobility of 0.0025 cm2·V-1·s-1.The perovskite had good spectral response in the UV-Vis range with good complementarity with C60.Planar het-erojunctions consisting of（3-BrC3H6NH3）2CuBr4/C60 were fabricated to study the charge transport and photovoltaic performance.The effects of annealing temperature and aggregation morphology of the films on the performance of the photovoltaic prototype were also investigated.The results showed that the best per-formance of the devices was obtained after the low temperature annealing treatment,which led to an ordered organic array in the perovskite.
