Constructing Molecular Bridging at the SnO2/Perovskite Interface for Efficient and Stable Perovskite Solar Cells.
Interfacial quality at the SnO2 electron transport layer (ETL)/perovskite junction critically governs the electron collection and device performance in n-i-p type perovskite solar cells (PSCs). However, the defects within SnO2 and at the buried interface can impede electron extraction and promote charge recombination....
