“…The results of the J – V characteristics of the devices in forward and reverse scanning also showed that the hysteresis of the Zr-SnO 2 device was obviously weakened after incorporation of ZrAcac (Figure S17). The hysteresis is closely related to the accumulation of ionic charge at the interface. ,− The mitigated hysteresis is consistent with the reduced interface charge density of the Zr-SnO 2 device.…”

SnO 2 is a promising material for use as an electron transfer layer (ETL) in perovskite photovoltaic devices due to its suitable energy level alignment with the perovskite, high electron mobility, excellent optical transmission, and low-temperature processability. The development of high-quality SnO 2 ETLs with a large coverage and that are pinhole-free is crucial to enhancing the performance and stability of the perovskite solar cells (PSCs). In this work, zirconium acetylacetonate (ZrAcac) was introduced to form a double-layered ETL, in which an ideal cascade energy level alignment is obtained. The surface of the resulting ZrAcac/ SnO 2 (Zr-SnO 2 ) layer is compact and smooth and had a high coverage of SnO 2 , which enhances the electron extractability, improves ion blocking, and reduces the charge accumulation at the interface. As a result, the fill factor (FF, 80.99%), power conversion efficiency (PCE, 22.44%), and stability of the Zr-SnO 2 device have been significantly improved compared to PSCs with only a SnO 2 ETL. In addition, the PCE of the Zr-SnO 2 device is maintained at more than 80% of the initial efficiency after 500 h of continuous illumination.

“…Zirconium acetylacetonate (ZrAcac) has been successfully used as a buffer layer between the active layer and the cathode or between the ETL and the cathode, resulting in enhanced electron extraction. − However, ZrAcac was mainly used in PSCs with a p-i-n structure, and it is rarely used in a n-i-p PSC with SnO 2 as the ETL.…”
