A key element in ensuring the high performance of PSCs is the charge transport layer (CTL), particularly the electron transport layer (ETL). The ETL plays a crucial role by efficiently collecting photo-generated electrons from the perovskite layer and transferring them to the transparent conductive oxide electrode. Among the materials used for ETLs, tin oxide (SnO<sub>2</sub>) stands out for its wide band gap, excellent optical transparency, superior carrier mobility, and remarkable chemical stability. Additionally, SnO<sub>2</sub> can be deposited at low temperatures, making it ideal for mass production and adaptable for applications such as flexible devices.
