摘要：

Despite dramatically improved efficiency of inorganic-organic metal hybrid perovskite solar cells (PSCs), electron transport is still a challenging issue. In this paper, we report the use of hydrothermal self-assembling ZnO nanorods as electron transport layer in perovskite solar cells. The efficiency of perovskite solar cells is dramatically enhanced by passivating the interface defects via atomic layer deposition of Al2O3 monolayers on ZnO nanorods. By employing Al2O3 monolayers, the power conversion efficiency (PCE) of CH3NH3PbI3 (MAPbI(3)) PSCs is typically boosted from similar to 10.38% to 14.27% on average, with the highest efficiency of 15.35%. We suggest that passivation of defects using atomic layer deposition of monolayers might provide a new pathway for improving all types of PSCs.
