Redox‐Active NiOx‐Catalyzed Li+ Capture‐Extraction Strategy for tBP‐Free Spiro‐OMeTAD Enables Exceptional Damp‐Heat Stability in Perovskite Solar Cells

Advanced Science, EarlyView.
The redox‐active nature of NiOx enables ultrafast oxidative doping of spiro‐OMeTAD within seconds. Concurrently, NiOx‐Li+ coordination complexes formed during this redox process are selectively removed by filtration, effectively extracting residual Li+ ions from the film.

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

Advanced Science, EarlyView.
ABSTRACT Stabilizing multiple elements within a single phase enables the creation of advanced materials with exceptional properties arising from their complex composition. However, under equilibrium conditions, the Hume–Rothery rules impose strict limitations on solid‐state miscibility, restricting combinations of elements with mismatched crystal ...

Meso‐Crowned Porphyrin as a Dual Cavity Hybrid Macrocycle for Improving the Efficiency and Stability of Perovskite Solar Cells

Advanced Science, EarlyView.
This study demonstrates a dual‐functional porphyrin‐based passivation molecule, [12]‐C‐4POR, capable of simultaneously coordinating Pb2+ and Li+ ions through its porphyrin core and crown ether moiety, respectively. This molecule effectively reduces trap‐state density, suppresses non‐radiative recombination, and mitigates Li+ migration at the perovskite/
