Molecularly Engineered Dual‐Crosslinked Polymer Dielectrics for 200 °C Capacitive Energy Storage
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work establishes a molecular engineering strategy that constructs a robust dual‐crosslinked network in polymer nanocomposites, achieving a record‐high energy density of 5.17 J cm−3 with >90% efficiency at 200 °C. The multiscale‐validated design simultaneously enhances dielectric polarization and introduces deep electron traps, resulting in ...

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

European railway reforms and efficiency: Review of evidence in the literature
Review of Economic Perspectives, 2017 The objective of the European railway reforms which started in the 1990s was to enable the entry of competition to raise the efficiency of railway transport. This was undertaken because the level of services, particularly in former Eastern Bloc countries,

Mechanical stability in flexible perovskite solar cells: Interface engineering and device design
FlexMat, EarlyView.Statistics of the improvement methods for f‐PSCs. Abstract Flexible perovskite solar cells (f‐PSCs) demonstrate significant potential for application in next‐generation wearable electronic devices and photovoltaic building integration due to their high power conversion efficiency and excellent power‐to‐weight ratio. However, the inherent brittleness of

Addition of regiorandom poly(3-hexylthiophene) to solution processed poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester graded bilayers to tune the vertical concentration gradient [PDF]
, 2012 Donor-acceptor vertical concentration gradient in the active layer is of crucial importance in graded bilayer poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) solar cells. We demonstrate that upon addition of regiorandom P3HT

Theoretical study on naphthobischalcogenadiazole conjugated polymer systems and C61 derivative as organic photovoltaic semiconductors [PDF]
Chemical Physics Letters, 2018 Abstract We investigated the charge-transfer reactions of solar cells including a quaterthiophene copolymer with naphtho-bis-thiadiazole (PNTz4T) and naphtho-bis-oxadiazole (PNOz4T) using constrained density functional theory (CDFT). According to our calculations, the high electron-transfer rate results in a highly efficient solar cell, and the ...
