ABSTRACT

Perovskite solar cells (PSCs) have emerged as the most promising solar cells due to their high efficiency and environmentally friendly characteristics. Additionally, titanium dioxide (TiO₂), with its excellent properties, has become the optimal choice for the electron transport layer (ETL) in perovskite devices. However, issues such as energy level mismatch between TiO₂ and perovskite light-absorbing materials have limited the efficiency of these devices. Therefore, this review primarily introduces the application of TiO₂ in PSCs and discusses the use of modified TiO₂ as ETL in perovskite devices. Finally, the existing problems and future research directions of TiO₂ in PSCs are proposed.
