Employment of Multifunctional Small Molecules in Buried Interfaces for Highly Efficient Perovskite Solar Cells
ions of perovskites, resulting in a uniform surface potential of HTLs, enhanced carrier transport, reduced defect density, and improved film quality of the perovskite. Consequently, the final PSCs present a champion efficiency of 25.46%, along with a significantly enhanced lifetime. The target device can maintain 91% of its initial efficiency after storage in a nitrogen environment for 1000 h and keep 87% efficiency after MPP tracking for around 950 h. This work provides a promising way for developing more effective buried interfaces for the advancement of PSCs.
