Controlling surface morphology of Ag-doped ZnO as a buffer layer by dispersion engineering in planar perovskite solar cells

Scientific Reports
In recent years, the power conversion efficiency (PCE (%)) of perovskite solar cells (PSCs) has improved to over 26%. To enhance the photovoltaic properties of PSCs, several materials for the electron transport layer (ETL) have been investigated.

Dual‐Polarization‐Sensitive Organic Photodetectors for Real‐Time Polarimetric Imaging

Laser &Photonics Reviews, EarlyView.
Bias‐switchable organic photodetectors with orthogonally stacked uniaxially oriented polymer layers enable dual‐polarization detection and real‐time polarimetric imaging. This scalable, template‐free strategy achieves a high dichroic ratio (>11), rapid response (>500 Hz), and detectivity up to 1013 Jones.

Timing Is Everything: How Subtle Timing Changes in MRI Echo Planar Imaging Can Significantly Alter Mechanical Vibrations and Sound Level

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Echo‐Planar Imaging (EPI) is central to fMRI, diffusion MRI, and many dynamic clinical applications, yet rapid gradient switching induces strong mechanical vibrations, generates acoustic noise, and contributes to ghosting artifacts—effects that intensify at ultra‐high fields.

Optimizing Selective RF Pulses for Enhanced Signal Stability in Turbo Spin Echo Using a Differentiable Extended Phase Graph Model

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve slice profile consistency across echo trains in turbo spin echo (TSE) imaging, thereby reducing image blurring and increasing the accuracy of multi echo spin echo T2$$ {T}_2 $$ mapping. Methods Excitation and refocusing RF pulses were optimized for TSE using a differentiable extended phase graph model that incorporates the ...

Impact of polymer aging on main‐chain poly(fullerene)s with halide chain‐ends for inverted perovskite solar cells

Polymer International, EarlyView.
Subtle variations in halogen chemistry significantly affect the aging behavior of polymeric electron transport layers in inverted perovskite solar cells, underscoring the importance of precise chemical design for enhancing long‐term stability. Abstract As perovskite solar cells (PSCs) advance toward commercialization, the need for stable and easily ...

On the Electron Transport in Simplified IBC‐SHJ Solar Cells With MoOx Blanket Layer

Progress in Photovoltaics: Research and Applications, EarlyView.
In this work, we present a study of electron transport through a novel (n)nc‐Si:H/MoOx stack to improve the understanding and performance of simplified IBC‐SHJ solar cells with MoOx blanket layer. The champion solar cell fabricated with the optimized contact stack and metalized with copper electroplating enables efficiencies beyond 23.5%.

Revealing the Energy Level and Charge Dynamics Interplay in Mixed Pb‐Sn Perovskite Solar Cells with Novel Phenoxazine and Phenothiazine Self‐Assembled Monolayers

Solar RRL, EarlyView.
Carbazole‐based self‐assembled monolayers (SAMs) have proven effective as HTLs in perovskite solar cells (PSCs). However, the energy alignment with narrow‐bandgap lead‐tin (Pb‐Sn) perovskites is suboptimal. Here, we design four phenoxazine/phenothiazine SAMs.

Early Introduction and Other Characteristics in Children With Suspected Severe Peanut or Tree Nut Allergy: Finnish Cohort

Acta Paediatrica, EarlyView.
ABSTRACT Aim Peanut and tree nut allergies are leading causes of food‐induced anaphylaxis in children. We aimed to examine early introduction and allergic characteristics in children with suspected severe peanut and/or tree nut allergy. Methods Children aged 3–16 years with suspected severe peanut and/or tree nut allergy were recruited from Tampere ...

Revisiting Asset Pricing Models: The Case for an Intangibles Factor

Financial Management, EarlyView.
ABSTRACT In an increasingly knowledge‐based economy, intangible assets may be an important driver of firm performance and stock returns. We introduce an intangibles intensity factor (INT), distinct from the organization capital factor, and show that exposure to this factor strongly predicts stock returns, outperforming traditional factors.

Addressing the Aging Workforce Crisis Through Intergenerational Programming: A Retrospective Analysis of Perfect Pair

Journal of the American Geriatrics Society, EarlyView.
ABSTRACT Background The growing older adult population in the United States creates a demand for professionals in the field of aging, though this remains a space that is overlooked by young adults beginning their career exploration. Perfect Pair is a nonprofit organization that connects older adults with college students to foster intergenerational ...
