Maximum power point tracking techniques for solar water pumping systems
Revue des Énergies Renouvelables, 2010 In this paper, we present a comparative study of single sensor-based maximum power point tracking (MPPT) techniques for solar photovoltaic (PV) water pumping systems. A conventional hill climbing algorithm is employed to find and track the MPP, using the

Maximum power point tracking for a photovoltaic power system [PDF]
, 2019 193 p. This dissertation proposes a novel maximum power point tracking (MPPT) algorithm that works optimally for a photovoltaic system under fast changing temperature and irradiation conditions. The new approach can effectively improve the tracking speed and accuracy simultaneously, which is the contradiction in conventional methods such as P&O or INC.

Advanced Functional Materials, EarlyView.By tuning the pore size of mesoporous N‐doped carbon (MPNC) nanospheres as support material for molybdenum sulfide, the electrochemical activity of the composite material for the hydrogen evolution reaction can be optimized. An ideal MPNC pore size of 60 nm allows a high number of molybdenum sulfide active sites while maintaining efficient proton and ...

Toughening β‐Ga2O3 via Mechanically Seeded Dislocations
Advanced Functional Materials, EarlyView.β‐Ga2O3 is promising for next‐generation semiconductors but its brittleness limits flexible and high‐precision applications. Here, mechanically seeded dislocations introduced by surface deformation improved damage tolerance in (001) β‐Ga2O3. Nanoindentation and characterization show dislocations suppress cleavage cracks by enabling stable plastic ...
