A novel shade-dispersion strategy for sustainable solar energy: Static sequential diagonal sudoku-based PV array configuration

Unconventional Resources
Photovoltaic (PV) systems often experience reduced power output due to partial shading from environmental factors like clouds, dust, trees, and buildings, creating uneven irradiation.

Influence of deposition temperature of thermal ALD deposited Al2O3 films on silicon surface passivation

AIP Advances, 2015
The effect of deposition temperature (Tdep) and subsequent annealing time (tanl) of atomic layer deposited aluminum oxide (Al2O3) films on silicon surface passivation (in terms of surface recombination velocity, SRV) is investigated. The pristine samples

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

Advanced 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 ...

Forward‐Biased Perovskite Photodiodes for In‐Sensor Optical Change Sensing

Advanced Functional Materials, EarlyView.
A forward‐biased perovskite photodiode is introduced as an in‐sensor analog preprocessing unit that uses current balancing between photocurrent and injection current to generate optical changes relative to programmable optical reference levels. The device directly converts reference‐relative optical changes into bipolar current signals, enabling sensor‐

Blue Upconversion Organic Light‐Emitting Diodes Achieving 1000 cd m−2 With an Operating Voltage of 2.7 V by Suppressing Interfacial Exciton Quenching

Advanced Functional Materials, EarlyView.
A triplet‐blocking layer controls triplet exciton dynamics in blue upconversion OLEDs. The layer keeps charge transfer (CT)‐generated triplet excitons inside the triplet‐triplet annihilation (TTA) host, suppresses anode‐side interfacial quenching, and increases the steady‐state triplet population.

Extended thermal admittance spectroscopy for the investigation of composition-dependent meta-stability behaviours in wide-gap (Ag,Cu)(In,Ga)Se2 solar cells

JPhys Energy
In this contribution, voltage- and temperature-dependent admittance spectroscopy is used in concert with other electrical characterisation techniques to gain insight into composition-dependent variations in the meta-stable behaviour of the (Ag,Cu)(In,Ga ...

Photoinduced Charge Separation in Single‐Component Squaraine Films: The Key Role of Electrostatic Disorder

Advanced Functional Materials, EarlyView.
ABSTRACT Neat films of organic dyes are an interesting technological platform for solar cells and photodetectors. Recently, the conventional biphasic bulk‐heterojunction paradigm for photoinduced charge separation was challenged by the observation that charge carriers can be photogenerated in single‐component materials. A comprehensive experimental and

Photoinduced Interfacial Electronic Modulation in Fe2O3‐BiVO4 Heterostructures for Enhanced Photo‐Assisted Zn‐Air Batteries

Advanced Functional Materials, EarlyView.
Light irradiation activates the Fe2O3‐BiVO4 heterostructure, enabling efficient solar‐electrochemical coupling in zinc‐air batteries. The built‐in electric field drives directional charge separation, guiding photoelectrons toward oxygen reduction sites and accumulating holes for oxygen evolution, thereby reducing polarization and enhancing discharge ...

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

Advanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.
