Enhancing Indoor Photovoltaic Efficiency to 37.6% Through Triple Passivation Reassembly and n‐Type to p‐Type Modulation in Wide Bandgap Perovskites

Advanced Functional Materials, EarlyView.
Triple Passivation Treatment (TPT) strategy enables 1.75 eV wide‐bandgap perovskite solar cells (WB‐PSCs) with suppressed halide phase segregation and n‐to‐p type surface transition. The photoluminescence quantum yield increases from 0.5 to 2.1%, indicating reduced non‐radiative losses.

1-(Phenylsulfonyl)naphthalene [PDF]

Acta Crystallographica Section E Structure Reports Online, 2012
In the title compound, C16H12O2S, the phenyl ring is nearly perpendicular to the naphthalene system [dihedral angle = 80.3 (1)°]. The packing is consolidated by a weak C—H...π interaction involving neighbouring naphthalene and benzene rings. In addition, there exist two different offset π–π stacking interactions between benzene rings and between ...

Na2S Presodiation Enables Long Cycling Anode‐Free Sodium Batteries via Rapid Spontaneous Reactions

Advanced Functional Materials, EarlyView.
Na2S with high sodium content is utilized as a sodium replenishment material for AFSBs. The spontaneous reaction between polysulfides and Na3−xV2(PO4)3, complete conversion from Na2S to sulfur is achieved under low voltage and catalyst‐free conditions. With the assistance of the additionally supplied sodium ions, the Na2S@NVP||Zn AFSBs retain 70.8% of ...

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

Advanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.
