Rationally Designed Bilayer Passivation Strategy for High‐Performance Vacuum‐Processed Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
A bilayer “Anchor‐and‐Seal” passivation strategy using EDAI2 and 4MeO‐PEAI effectively mitigates surface defects in vacuum‐processed perovskite films through synergistic hydrogen bonding and Lewis base coordination. This approach optimizes interfacial energy alignment and suppresses non‐radiative recombination, enabling vacuum‐deposited p‐i‐n ...

Relationship between solar wind corotating interaction regions and the phasing and intensity of Saturn kilometric radiation bursts [PDF]

, 2008
Voyager spacecraft measurements of Saturn kilometric radiation (SKR) identified two features of these radio emissions: that they pulse at a period close to the planetary rotation period, and that the emitted intensity is correlated with the solar wind ...

Solar-Wind Origin

, 2019
Abstract The Sun continuously expels a fraction of its own mass in the form of a steadily accelerating outflow of ionized gas called the “solar wind.” The solar wind is the extension of the Sun’s hot (million-degree Kelvin) outer atmosphere that is visible during solar eclipses as the bright and wispy corona.

Solvent Co‐Intercalation Enabled Ca Storage in MoS2 for Ca‐Ion Batteries

Advanced Functional Materials, EarlyView.
Regulating electrolyte solvation levels enables otherwise non‐intercalatable Ca2+ ions to reversibly co‐intercalate into molybdenum disulfide (MoS2) as ether‐solvated species. The intercalation reversibility is strongly governed by solvent chain length, as demonstrated using diethylene glycol dimethyl ether (G2) and tetraethylene glycol dimethyl ether (

Online evaluation method for MMC submodule capacitor aging based on CapAgingNet

Global Energy Interconnection
Submodule capacitor aging poses significant challenges to the safe operation of modular multilevel converter (MMC) systems. Traditional detection methods rely predominantly on offline tests, lacking real-time evaluation capabilities.

Exploring Pb‐Chelation Chemistry in the Crystallization Dynamics of Halide Perovskites

Advanced Functional Materials, EarlyView.
A mechanism of how Pb‐chelation chemistry governs coordination geometry and initial nucleation behavior at the precursor level of halide perovskite, by regulating the deprotonation state of a chelating additive, is elucidated. This allows for innovative reaction‐system design principles that promote coherent growth while suppressing defect formation in

Characteristics of Solar Wind Density Depletions During Solar Cycles 23 and 24 [PDF]

Journal of Astronomy and Space Sciences, 2017
Solar wind density depletions are phenomena that solar wind density is rapidly decreased and keep the state. They are generally believed to be caused by the interplanetary (IP) shocks.

Dual‐Function Interface Engineering for δ‐Phase‐Free Crystallization Toward Efficient and Stable FAPbI3 Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
This work presents a dual‐function interface engineering strategy using PEACl to suppress the formation of the non‐perovskite δ‐FAPbI3 phase at the critical SnO2 buried interface. This approach enables the direct crystallization of the photoactive α‐phase, yielding highly efficient and stable rigid (25.6%) and flexible perovskite solar cells with ...

Heating of the low-latitude solar wind by dissipation of turbulent magnetic fluctuations

, 2001
We test a theory presented previously to account for the turbulent transport of magnetic fluctuation energy in the solar wind and the related dissipation and heating of the ambient ion population. This theory accounts for the injection of magnetic energy

The statistical dependence of auroral absorption on geomagnetic and solar wind parameters [PDF]

, 2004
Data from the Imaging Riometer for Ionospheric Studies (IRIS) at Kilpisjärvi, Finland, have been compiled to form statistics of auroral absorption based on seven years of observations.
