Global maximum power point tracking in partially shaded PV systems using plant reproduction algorithm

IET Renewable Power Generation, 2021
The power–voltage curve of photovoltaic (PV) power generation system under partial shading conditions (PSC) is non‐monotonic with multiple power peaks and traditional methods do not guarantee global convergence which leads to energy loss.

A new MPPT control for photovoltaic panels by instantaneous maximum power point tracking

Electrical Engineering in Japan, 2004
AbstractThis paper presents a new maximum power point tracking control for photovoltaic (PV) panels. The control can be categorized into the Perturb and Observe (P&O) method. It utilizes instantaneous voltage ripples at PV panel output terminals caused by the switching of a chopper connected to the panel in order to identify the direction for the ...

Phase‐Pure 2D Interfacial Perovskite Passivation for Stable and Efficient Photovoltaics

Carbon Energy, EarlyView.
Phase‐pure 2D interfacial passivation eliminates mixed‐phase energetic disorder, establishes favorable band alignment, and suppresses interfacial non‐radiative recombination. This review elucidates deterministic phase‐purity control, defect and lattice reconstruction mechanisms, and scalable manufacturing strategies, highlighting how phase‐pure 2D/3D ...

Modulating Perovskite Crystallization via Multisite Bonding for Enhanced Solar Cell Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study proposes an innovative multisite bonding strategy to regulate crystallization. By employing bidentate ligands N,N‐diethyl‐1,2‐ethanediamine dihydrochloride (DED) that coordinate with uncoordinated Pb2+ and I− vacancies, while simultaneously forming hydrogen bonds with FA+ ions, this synergistic interaction prolongs the perovskite ...

A Practical Real‐Time Observer‐Based Radiation Prediction Algorithm for Solar Plants

Energy Science &Engineering, EarlyView.
A novel radiation prediction method is proposed. The model's existence is verified by applying real data to an offline identifier. An adaptive state/parameter estimator is developed to identify the model. The identification process occurs in real‐time, independent of specific situations. The method offers universal radiation prediction.
