Alkylthienyl Side Groups in Conjugated Polymers Enable Localization of π Electron Density and Facilitate Efficient Hole Transfer

Advanced Science, EarlyView.
Resonance Raman spectroscopy is used in combination with other spectroscopic and morphology characterization techniques to unveil the mechanistic origin of the shift in synthetic strategy to alkylthienyl peripheral groups for high‐performing organic photovoltaics.

Imperfection in Semiconductors Leading to High Performance Devices

Advanced Science, EarlyView.
Crystalline perfection is typically pursued in semiconductors to enhance device performance. However, through modeling and experimental work, we show that defects can be strategically employed in a specific detection regime to increase sensitivity to extreme values. GaN diodes are demonstrated to effectively detect high‐energy proton beams at fluxes as

Thermodynamically Reinforced Dual‐Interface 1D/3D Tin‐Lead Perovskite Heterostructure for Stable All‐Perovskite Tandem Solar Cells

Advanced Science, EarlyView.
A π‐conjugated diammonium additive is employed to engineer a dual‐interface 1D/3D perovskite heterostructure. π‐π stacking 1D perovskitoids act as nucleation templates to relieve tensile strain and intra‐/intergranular disorder and then encapsulate the 3D bulk to fortify the Sn‐I octahedral framework. The all‐perovskite tandem devices based 1D/3D Sn‐Pb

Truncated Conjugate Structure Improves Solar‐Driven Hydrogen Peroxide Production Catalyzed by Benzobisthiazole‐Based Conjugated Polymers

Advanced Science, EarlyView.
In this work, a novel molecular design strategy was employed to truncate large‐scale conjugated structures in covalent polymer materials. This approach significantly enhances the catalyst’s light‐harvesting capability, prolongs the lifetime of photogenerated charge carriers, and improves catalytic activity, thereby offering a new conceptual pathway for
