Fully vacuum‒processed perovskite solar cells with VOC of 1.12 V emplying MoO3/NPB layer |
| 초록 |
We report fully vacuum‒processed perovskite solar cells with high open circuit voltage using MoO3/NPB as hole extraction layers. All the layers in the solar cells including the perovskite active layer, hole extraction layers and electron extraction layers were deposited via the vacuum process. Use of molybdenum oxide (MoO3) as an interfacial layer and N,N′-Di(1-naphthyl)-N,N′-diphenyl-(1,1′-biphenyl)-4,4′-diamine (NPB) as a hole transport material (HTM) for hole extraction resulted in a high value of open circuit voltage (VOC) of 1.12 V. Due to the effective hole extraction and high VOC, the devices showed a maximum power conversion efficiency (PCE) of 13.7%. The vacuum processed perovskite solar cells showed relatively high reproducibility showing the average value of PCE of 11.1% among 72 devices from 6 different batches. |
