Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

The Effect of Pore Functionality in Multicomponent Covalent Organic Frameworks on Stable Long‐Term Photocatalytic H2 Production

open access: yesAdvanced Energy Materials, EarlyView.
Five COFs are synthesized through a multicomponent reaction, preserving a similar backbone while introducing varying pore functionalities. All COFs demonstrate excellent chemical stability and sustained H2 production under sunlight for 7‐15 days. The imidazole‐functionalized COF exhibits the highest H2 production, which can be attributed to its high ...

Low‐Carbon Poly(3‐vinyl‐N‐methylphenothiazine) Electrode Formulation Using PEDOT:PSS (poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate)) for Lithium‐Based Energy Storage

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Organic electrode materials typically suffer from low electronic conductivity, requiring large amounts of carbon additives. Herein, a conducting polymer, PEDOT:PSS, is introduced as a partial replacement for carbon black, reducing the carbon content to 15 wt%.

Transcranial Direct Current Stimulation Neuromodulation in Elderly Individuals and Its Impact on Anxiety and Depression Symptoms

open access: yesAGING MEDICINE, EarlyView.
Anodal tDCS over the left prefrontal cortex, combined with cognitive training, enhanced cognition, reduced anxiety and depression, and improved motor response in elderly women. These findings support tDCS as a safe, effective strategy for promoting brain plasticity and mental health in aging.
