A Comprehensive Multistage Average Controller for Trajectory Tracking in Solar‐Powered Mobile Robots: Analysis of Actuator‐Driver and Power Stage Integration

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies

Defect Passivation via Plasma Modification of Lead Halide Perovskite Thin Films

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
We demonstrate that exposure of perovskite thin films to diffuse coplanar surface barrier discharge nitrogen plasma leads to an increase in photoluminescence, attributed to reduced defect densities. This results in implied open‐circuit voltage improvement of up to 80 mV and finalized solar cell open‐circuit gains up to 60 mV.

Efficient and Durable Semitransparent Perovskite Solar Cells for the Application in 4T Perovskite/c‐Si Tandem Devices

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
We present an optimized fabrication strategy incorporating a solution‐processed SnO2 buffer layer that prevents sputter‐induced damage during TCO deposition, enabling semitransparent perovskite solar cells with 21.87% efficiency, 27.15% in tandem, and exceptional long‐term stability under continuous illumination and outdoor conditions.

A Self‐Supervised Machine Learning Approach for the Estimation of Open‐Circuit Voltage Degradation in Photovoltaic Systems

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
This study introduces a self‐supervised machine learning approach integrating physics‐based principles to estimate open‐circuit voltage (voc$$ {v}_{oc} $$) degradation in photovoltaic systems using SCADA data. By combining clustering and regression algorithms, our method detects performance deviations without labelled datasets.

Anisotropic Diffuse Radiation Model of Photovoltaic Systems

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
Monthly incident diffuse energy—isotropic and anisotropic models. ABSTRACT The diffuse solar radiation is a component of the global solar radiation and may contribute a significant percentage (50% and above in some locations) of the electric output energy of Photovoltaic (PV) systems.
