Electrochemical Formation of BiVO4/BiPO4 Photoanodes for Enhanced Selectivity toward H2O2 Generation

open access: yesAdvanced Functional Materials, EarlyView.
In acidic KPi, V dissolves from the BiVO4 lattice, while adsorbed phosphate reacts with the electrode under an external bias, forming a BiPO4 surface layer. This BiPO4 layer exhibits stronger bicarbonate adsorption, redirecting the water oxidation pathway toward two‐electron H2O2 production.

Logarithmic PSO-Based Global/Local Maximum Power Point Tracker for Partially Shaded Photovoltaic Systems

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2022
It is well known that under partial shading conditions, Photovoltaic generator power-voltage characteristic presents over one maximum due to the use of bypass diodes. Classical Hill Climbed methods cannot found the global maximum and often converges to a local maximum. Among numerous optimization methods used to track the global maximum, Particle Swarm

Eliminating The Problem of Trapping in Local Maximum Power Point under Partial Shading Conditions for PV System

2019 IEEE 4th International Future Energy Electronics Conference (IFEEC), 2019
This study realizes a new solar-power generation system that can complete the global maximum power point tracking (GMPPT) control under uniform irradiation and partial shading conditions (UIC and PSC, respectively). The MCU of the proposed system calculates the I GMPP of the photovoltaic (PV) module to accurately execute GMPPT on the basis of the PV ...
