Gate-Tunable Polarity-Reconfigurable Photovoltaic Response With Dual Linearity in NbS₃/WSe₂ Heterostructures for In-Sensor Image Processing. [PDF]

Adv Sci (Weinh)
An NbS3/WSe2 van der Waals heterostructure realizes a continuously gate‐tunable self‐powered photovoltaic response through interfacial band‐alignment modulation and reversible built‐in electric‐field switching. The short‐circuit photocurrent scales linearly with incident power density, while short‐circuit photoresponsivity varies linearly with gate ...

Flexoelectric Suppression of Interfacial Carrier Loss in BaTiO₃ Thin-Film Bulk Photovoltaic Systems. [PDF]

Adv Sci (Weinh)
In single‐crystalline BaTiO3 thin films, flexoelectric strain gradients strongly enhance photocurrent by suppressing interfacial carrier loss. Loading experiments reveal a ∼35‐fold photocurrent increase with applied force. Self‐consistent electrostatic modeling shows that strain gradients reshape the interfacial potential landscape, strengthen local ...

A New Ken-Ken Puzzle Pattern Based Reconfiguration Technique for Maximum Power Extraction in Partial Shaded Solar PV Array

IEEE Access, 2021
Solar Photovoltaic array may often be subjected to partial shading, which may lead to uneven row current and creates local maximum power point on the power-voltage characteristics.

Performance of PV array configurations under dynamic partial shadings

EPJ Photovoltaics, 2023
The partial shading effect (PSE) is responsible for most power losses in a photovoltaic (PV) system. By modifying the interconnections between PV modules, called PV array reconfiguration, it is possible to improve the power output under partial shading ...
