Perovskite solar cells (PSCs) with SnO2 electron transporting layer (ETL) prepared using new methods demonstrate stronger charge extraction capabilities and achieve high performance. Research progress in SnO2 nanostructures and preparation methods, as well as passivation options like elemental doping, bilayer alterations, and interfacial modifications, can effectively enhance the efficiency of PSCs.
Perovskite solar cells (PSCs) have recently demonstrated a rapid power conversion efficiency of above 25%. In terms of physical properties, SnO2 is similar to TiO2 but with stronger charge extraction at the interface. Furthermore, the SnO2 electron transporting layer (ETL) is prepared using new, simple, and efficient methods, resulting in high-performance PSCs. This review initially described recent progress in SnO2 nanostructures and preparation methods. The passivation options were then divided into elemental doping, bilayer alterations, and interfacial modifications. Finally, we discussed the challenges and limitations of SnO2 ETL-based PSCs and made recommendations for further research.
