AbstractHigh efficiency organic-inorganic hybrid perovskite solar cells have experienced rapid development and attracted significant attention in recent years. Electron transport layers (ETLs) play an important role in extracting and transporting electrons in devices. To date, the most widely used ETL is still based on TiO2, whereas studies on other novel ETLs are not sufficient. A novel mesoporous ETL based on La-doped BaSnO3 (LBSO) has been investigated herein. The LBSO nanoparticles were synthesized under relatively mild conditions and proven to be a suitable material for mesoporous ETL. After optimization, mesoporous LBSO-based solar cells exhibited the best power conversion efficiency of 15.1%. By comparing mesoporous LBSO, BSO, and TiO2-based devices, the LBSO-based devices exhibit the highest J(sc), which can be attributed to the much higher electron mobility of LBSO. The electron transport and recombination were investigated by photoluminescence (PL) spectrum and transient absorption spectrum (TAS). The LBSO-based devices exhibit efficient electron transport and low recombination.
