제목 Improved Efficiency and Air-stability of Inverted Perovskite Solar Cells via PCBM Electron Transporting Layer Modification Using Triton X–100
초록 We modified phenyl-C61-butyric acid methyl ester (PCBM) for use as a stable, efficient electron transporting layer (ETL) in inverted perovskite solar cells (PSCs). PCBM containing a surfactant Triton X–100 acts as the ETL and NiOX nanocrystals act as a hole transporting layer (HTL). Triton X–100 added to PCBM solution improves interfacial properties of the ETL and accelerates electron transport from perovskite absorber to the electrode. When the modified PCBM was used, the average power conversion efficiency increased from 10.76% to 15.68%. Our PSCs also showed good air-stability, retaining 83.8% of its initial performance after 800-h exposure in ambient condition.
