Defect‐Passivating and Dense Indolocarbazole‐Based Self‐Assembled Monolayers for Efficient Inverted Perovskite Solar Cells With over 26.1% Efficiency

Small, EarlyView.
This study proposes a strategy to modulate nitrogen positions (meta‐/para‐) in indolocarbazole units and the number of anchoring groups (mono‐/bis‐phosphonate), achieving a remarkable PCE of 26.12%, among the highest reported for PSCs using indolocarbazole‐based SAMs as HTLs.

Strained 2D Semiconductor Lateral Heterojunctions via Grayscale Thermal‐Scanning Probe Lithography

Small Science, EarlyView.
A novel strain‐engineering approach using grayscale thermal‐Scanning Probe Lithography tailors the optoelectronic response of 2D Transition‐Metal Dichalcogenide (TMD) layers. Nanofaceted templates control local strain in MoS2, enabling engineered carrier extraction in asymmetric Au‐MoS2 lateral heterojunction nanoarrays, as detected by Kelvin Probe ...

Suppressing NiOx/CsPbIBr2 Interfacial Redox Reactions and Band Energy Misalignment in Perovskite Solar Cells

Small Methods, EarlyView.
High‐performance inverted inorganic CsPbIBr2 perovskite solar cells are achieved by introducing a N‐dodecylphosphonic acid interlayer at the NiOx/CsPbIBr2 interface. ABSTRACT Inverted inorganic CsPbIBr2 perovskite solar cells (PSCs) employing NiOx as the hole‐transport layer are promising long‐term stable and semi‐transparent photovoltaic devices ...

Coupled Ferroelectric–Photoelectrochemical in Water Reduction Over BiFeO3 Thin Film Heterostructure Modulated by Rare‐Earth Doping

Advanced Functional Materials, Volume 36, Issue 11, 5 February 2026.
Gd‐doped BFO (BGFO) exhibits a ∼2‐order reduction in leakage current owing to its lowest content of oxygen vacancies. This leads to a ∼2.5‐fold increase in remnant polarization. These improvements in BGFO effectively boost charge separation and transportation, resulting in the greatest incident photon‐to‐current efficiency of 12.9 ± 0.73% and a ∼1.5 ...
