Gas–Solid Interface‐Assisted Growth of Organic Semiconductor Single Crystals: Dimensions, Structures, Mechanisms, and Applications

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Gas–solid interface‐assisted growth strategies have unlocked precise control over crystal structure, morphology, dimension, and molecular packing. The obtained organic semiconductor single crystals represent the ideal candidates for high‐performance organic optoelectronic devices.

A Co‐Self‐Assembled Monolayer With Enhanced Coverage and Defect Passivation for Efficient Inverted Perovskite Solar Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study achieved a co‐self‐assembled monolayer (Co‐SAM) with more uniform coverage on nickel oxide substrates and enhanced passivation of buried interfaces by incorporating 4PABCz into Me‐4PACz. Perovskite solar cells fabricated with this Co‐SAM achieved an efficiency of 26.33% and exhibited enhanced stability. The combination of nickel oxide (NiOx)

Managing Crystallization in Tin‐Lead Perovskite Solar Cells via Differential Chelating Coordination

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A chelation‐mediated crystallization strategy is developed for Sn–Pb perovskites using 1,10‐phenanthroline. Stronger coordination with Sn than Pb helps reconcile their mismatched crystallization behavior, leading to improved crystalline quality, fewer defects, and reduced oxidation.

Three Birds with One Stone: High‐Performance 2D Lead‐Free Perovskite Solar Cells via Direct In Situ Generation of Organic‐Spacer Precursors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Adopting a “three birds with one stone” strategy, the in situ generation of organic spacer simultaneously addresses three major challenges limiting 2D tin‐based perovskites: (1) Sn2+ oxidation; (2) rapid crystallization; and (3) uncontrolled 2D phase distribution.

Varieties of Local Implementation for Net Zero in China: Evidence From Three Cities

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Since China updated its nationally determined contributions in 2021, achieving carbon peaking before 2030 and carbon neutrality before 2060—the so‐called “dual carbon” goals—has become the new guiding principle of China's climate governance. However, few studies have examined the implementation of China's dual carbon goals, particularly the ...
