제목 Spray Deposited Metal Oxide Electron Transport and Hole Transport Layers for Perovskite Solar Cells
초록 Perovskite solar cells (PSCs) have been intensively investigated because of their high efficiency and low processing costs. A great deal of effort is required in designing complex nanostructures which are effective as ETL/HTL to achieve high open circuit voltage and high fill factor in PSCs. Nanostructured ETL/HTL such as nanowire, nanorods and nanoporous films with better surface morphology, roughness, and nanoarchitecture were found to be beneficial for giving efficient electron injection and a short carrier path for the electron. In this work, various metal oxide films with nanostructured morphology and plasmonic properties have been fabricated by one-step spray pyrolysis technique and applied to the PSC devices. The WO3 based ETL exhibit the device efficiency of ~7% with high Jsc~ 22 mA/cm2. We expect to achieve high efficiency >15% after alignment of energy levels of ETL with perovskite layer.
