Abstract Roughness and fragility of bottom-up interfaces in perovskite solar cells accelerate device degradation and increase maintenance costs, while conventional interface engineering often fails to address issues at multiple interfaces simultaneously. Here, trimethyl(cyanomethyl)ammonium iodide is employed for a dual-interface self-regulation.

In situ synthesis of lithiophilic Ag sites in 3D MOF-derived nitrogen-doped porous carbon composites towards dendrite-free lithium metal anodes† The uncontrolled dendritic lithium growth and excessive volume expansion pose significant challenges to the practical applications of metallic lithium, which is considered as the most promising high-energy-density anode material for rechargeable batteries.
