Summary: In this work, 2D Nb2CTx MXene nanosheets were prepared and used as electron transport layer (ETL) materials in perovskite solar cells. By altering the surface groups of the MXene nanosheets, the work function was matched with the conduction band minimum of the perovskite layer, resulting in improved performance of the solar cells. Additionally, the incorporation of treated MXene nanosheets into the perovskite precursor helped in the formation of high-quality and oriented growth perovskite films, leading to higher power conversion efficiency (PCE). The flexible and large-area devices with MXene ETLs and additives achieved the highest PCE. Furthermore, the unencapsulated devices demonstrated good stability after long-term storage.
