Room Temperature Processed Double Electron Transport Layers for Efficient Perovskite Solar Cells.

ABSTRACT: Zinc Oxide (ZnO) has been regarded as a promising electron transport layer (ETL) in perovskite solar cells (PSCs) owing to its high electron mobility. However, the acid-nonresistance of ZnO could destroy organic-inorganic hybrid halide perovskite such as methylammonium lead triiodide (MAPbI₃) in PSCs, resulting in poor power conversion efficiency (PCE). It is demonstrated in this work that Nb₂O₅/ZnO films were deposited at room temperature with RF magnetron sputtering and were successfully used as double electron transport layers (DETL) in PSCs due to the energy band matching between Nb₂O₅ and MAPbI₃ as well as ZnO. In addition, the insertion of Nb₂O₅ between ZnO and MAPbI₃ facilitated the st
