Summary: Sodium and potassium ions batteries (SIBs, PIBs) have attracted wide concerns as the ideal substitutes for lithium-ion batteries (LIBs) used in large-scale energy storage, thanks to their similar working principle to LIBs, rich abundance, and low cost. However, the shortage of suitable anode materials poses a key challenge in the field of Na+/K+ storage. Molybdenum chalcogenides have drawn great attention as anode materials for SIBs/PIBs due to their special electronic/crystal structures and high specific capacities. However, their volumetric fluctuation and low electrical conductivity are the main obstacles that hinder their performance.

Summary: The metallic electrode interfacial properties greatly influence the performance of photovoltaic devices. The interaction between the aluminum electrode and PCBM in two-dimensional perovskite photovoltaic devices is investigated. It is found that the aluminum oxide dielectric layer formed at the interface contributes to achieving a high voltage in these devices. Further optimization of the device performance can be achieved by regulating the aluminum oxide layer. The capacitive effect of the aluminum oxide dielectric layer is responsible for this high voltage response. This work serves as a reference for future research on the electrode/PCBM interface in perovskite photovoltaic devices.
