摘　　要：以有机小分子浴铜灵(BCP)作为缓冲层,引入钙钛矿太阳能电池的电子传输层与阴极之间,研究其对钙钛矿太阳能电池的能量转换效率及载流子的传输特性的影响。结果表明,相对于无BCP缓冲层的钙钛矿太阳能电池,器件的最高能量转换效率由9.67%提高到13.06%。BCP缓冲层的引入,降低了电荷传递电阻,提高了阴极的电子收集能力,可增强钙钛矿太阳能电池的光伏性能。In this paper,we used the small organic molecules Bathocuproine(BCP)as the buffer layer between the electron transport layer and the cathode of the perovskite solar cells and investigated its influence on the power conversion efficiency and the carrier transport characteristics of perovskite solar cells.The results showed that the maximum power conversion efficiency of the device with BCP buffer layer increased from 9.67%to 13.06%compared with the control device.Because of the BCP being utilized in the device as the buffer layer,the charge transfer resistance decreased and the charge collection ability obviously increased,thus the photovoltaic performances of perovskite solar cells were improved.
