摘 要: 研究报道了一种基于ZnO/PCBM 核壳纳米棒阵列的钙钛矿太阳能电池(perovskite solar cell,PSC)。PCBM不仅可以修饰ZnO 纳米棒阵列,还可以调整能级结构,减小电子和空穴在传输过程中的能量损失,从而提高器件的光伏性能。通过PCBM 的修饰作用,器件的短路电流密度(Jsc)从18.95 mA·cm−2 增加至22.06 mA·cm−2,增加了16.4%;器件的开路电压(Voc)从0.78 V 增加至0.96 V,增加了23.1%;器件的能量转化效率(power conversion efficiency,PCE)从7.4%增加至11.67%. 此外,该器件也展现出了较好的稳定性,在手套箱放置50 d后的能量转化效率仍然保持在90%左右。

Abstract: This paper studies the pervoskite solar cell (PSC) based on ZnO/PCBM core-shell nanorod arrays. PCBM can not only modify the ZnO nanorod arrays, but also adjust the energy levels, reduce the energy loss during the transmission of electrons and holes, and ultimately improve the photovoltaic performance of the PSC. Through the modification of PCBM, the short-circuit current density (Jsc) of our device increased from 18.95 mA·cm−2 to 22.06 mA·cm−2 with an increase of 16.4%. The open-circuit voltage (Voc) increased from 0.78 V to 0.96 V with an increase of 23.1%, and power conversion efficiency (PCE) of the device increased from the original 7.4% to 11.67%. In addition, the device also exhibits good stability that it has kept an efficiency of around 90% when being placed in glove box for 50 d.
