Heterointerface‑Enabled Electrocatalysis for Efficient Energy Conversion

Advanced Science, EarlyView.
Functionally distinct A/B materials can be integrated at the nanoscale to create customized heterointerfaces with tunable band alignment and charge redistribution, providing fast electron and ion transport channels as well as cooperative dual active sites.

Tracing the Dynamic Chemical Transformations of Spiro‐OMeTAD in Operating Perovskite Solar Cells

Advanced Science, EarlyView.
Mapping of Spiro‐OMeTAD layer's chemistry and electronic properties in PSC: Advanced cluster ion‐beam sputtering depth profile XPS reveals that environmental stressors (light, potential, and moisture) trigger the decomposition of LiTFSI dopants in Spiro‐OMeTAD.

Electrostatic Potential Complementarity for Thickness‐Tolerant Cathode Interlayers in High‐Efficiency Organic and Tandem Solar Cells

Advanced Science, EarlyView.
Two model molecules — trimesic acid (TMA) and phloroglucinol (PG) — with opposite central electrostatic potential (ESP) distributions are employed to elucidate how molecular electrostatic interactions regulate the cathode interlayer (CIL) PDINN. Electrostatic potential complementarity is revealed as the intrinsic origin of thickness sensitivity in CILs,

Degradation Mechanisms Associated with Electron‐Blocking Layers in Inverted Perovskite Solar Cells

Advanced Science, EarlyView.
The effects of the three typical EBLs NiOx, PTAA, and 2PACz on the photovoltaic performance and degradation mechanisms are investigated under light soaking and solar‐thermal cycling conditions of corresponding PSCs, demonstrating that 2PACz is the best EBL due to the better interface contact and lower lattice distortion.

Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction

Advanced Science, EarlyView.
The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.
