Application of Photovoltaic Power Optimizer in Distributed Photovoltaic Power Generation System

DEStech Transactions on Engineering and Technology Research, 2018
Compared with centralized photovoltaic power generation systems, the distributed generation system's power generation conditions are more complex and changeable, and are extremely susceptible to environmental impacts. To study the mismatch problem of distributed generation systems, a parallel-connected single-switch photovoltaic optimizer circuit was ...

A Universal Interfacial Dipole Strategy for Defect Suppression in Inverted Perovskite Solar Cells With Tunable Bandgaps

Advanced Functional Materials, EarlyView.
A 2D heterointerface with a two‐site anchor bridge suppresses nonradiative recombination at the perovskite/C₆₀ interface by reducing surface defects, elevating the Fermi level, and strengthening the electric field. This strategy enables efficient electron extraction, delivering 26.32% efficiency, 1.217 V Voc, excellent operational stability, and broad ...
