Robust PWM control scheme for switched-capacitor MLI with leakage current suppression in grid-connected renewable energy application

Heliyon
Typically, parasitic capacitances exist between the ground and the solar panel terminals in grid-connected PV systems. These parasitic capacitances provide a path for a leakage current, which leads to significant safety concerns, observable and seriously

Post‐Deposition Photonic Curing Treatment for Improved Sb2Se3 Photovoltaic Performance

Advanced Optical Materials, EarlyView.
Millisecond‐scale photonic curing overcomes the open‐circuit voltage deficit in Sb2Se3 solar cells by transforming the rear interface. This ultrafast treatment enhances crystallographic texture and smooths the absorber surface, suppressing interfacial recombination and boosting power conversion efficiency to 8.2%.

Soft Robotic Excretory Care Simulator for Nursing Education: Functional and Perceptual Biomimetics Approach

Advanced Robotics Research, EarlyView.
A soft robotic simulator is developed to replicate the digital removal of feces (DRF), a sensitive yet essential nursing procedure. Integrating soft actuators, sensors, and a realistic rectal model, the simulator balances functional fidelity with perceptual realism. Engineering evaluations and nurse feedback confirm its potential to enhance training in
