Abstract
All-inorganic cesium lead triiodide (CsPbI3) perovskites have attracted much attention because of their intrinsic chemical stability and suitable bandgap for photovoltaic applications. However, simple methods to synthesize pure CsPbI3 have been limited. Here, we develop a new mediator–antisolvent strategy (MAS) combining phenyl-C61-butyric acid methyl ester (PCBM) blended chlorobenzene (CBZ) antisolvent and methylammonium iodide (MAI) mediator to synthesize high-quality and stable black-phase CsPbI3 perovskite films. The crystallization process is altered by the blended antisolvent, leading to a smaller crystallite of the perovskite with improved stability. The small amount of MAI acts as mediator and further improves the quality of the CsPbI3 films in morphology and photoelectronic properties. Finally, the power conversion efficiency of CsPbI3 perovskite solar cells prepared by the strategy significantly increases to a value of ≥16% with good reproducibility. Moreover, the devices retain 95% of their original efficiency over 1000 h.
