Abstract
Tin oxide (SnO2) is a commonly used electron-transporting material (ETM) in perovskite solar cells (PSCs) due to its low-temperature processability and suitable energy levels. However, its inherent limitations, such as insufficient electron mobility and high density of trap states, hinder further improvement of device performance. This review explores recent advances in modifying SnO2 ETMs to address these limitations and improve the efficiency and stability of n-i-p PSCs. We delve into the role of various dopants and surface modification strategies in enhancing electron transport properties and reducing the trap states. By elucidating the impacts of dopant chemical/electronic structures and surface treatments on SnO2 properties, this review provides valuable insights for the development of efficient ETMs for high-performance PSCs.

期刊介绍：
Solar RRL, formerly known as Rapid Research Letters, has evolved to embrace a broader and more encompassing format. We publish Research Articles and Reviews covering all facets of solar energy conversion. This includes, but is not limited to, photovoltaics and solar cells (both established and emerging systems), as well as the development, characterization, and optimization of materials and devices. Additionally, we cover topics such as photovoltaic modules and systems, their installation and deployment, photocatalysis, solar fuels, photothermal and photoelectrochemical solar energy conversion, energy distribution, grid issues, and other relevant aspects. Join us in exploring the latest advancements in solar energy conversion research.
