Oligoethylene Glycol Side‐Chain Engineering of Y6‐Derived Nonfullerene Acceptors for Thermally Induced Spontaneous Pseudo‐Planar Heterojunction Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
OEG‐functionalized Y6‐derived acceptors induce thermally driven vertical phase separation, enabling pseudo‐planar heterojunction organic photodetectors. The resulting PM6:YTEG‐4F and PM6:YTEG‐4Cl organic photodetectors suppress dark current density by approximately 260‐fold and 210‐fold, respectively, while maintaining efficient photoresponse ...

ADAPTIVE MAXIMUM POWER POINT TRACKING ALGORITHM FOR MULTI-VARIABLE APPLICATIONS IN PHOTOVOLTAIC ARRAYS

open access: yesRevista EIA
Classical algorithms for multi-variable photovoltaic systems use fixed-size perturbations, which does not optimize the produced power in both steady-state and transient conditions.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

open access: yesAdvanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Desert Plant Inspired Hierarchical Nanofibrous Membranes for Integrated Solar Desalination and Heavy Metal Remediation

open access: yesAdvanced Functional Materials, EarlyView.
An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

Application perturb and observe maximum power point tracking technique for CubeSat power systems

open access: yes
The Cube Satellite (CubeSat) power availability depends firstly on solar panel power generation and secondly on battery storage capacity. In a CubeSat mission, the solar panels must fit on the outside walls of a 10cm3 volume. Hence, a maximum power point

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

open access: yesAdvanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

Multi-Peak Photovoltaic Maximum Power Point Tracking Method Based on Honey Badger Algorithm Under Localized Shading Conditions

open access: yes
The P-V and I-V curves of photovoltaic (PV) strings show multiple peaks when exposed to partial shading conditions (PSCs). The traditional maximum power point tracking (MPPT) method cannot track the global maximum power point (GMPP) due to the multi-peak
