Power optimization in partially shaded photovoltaic systems [PDF]

, 2018
The Power-Voltage characteristic of a photovoltaic (PV) array exhibits non-linear behaviour when exposed to uniform solar irradiance. Maximum Power Point (MPP) tracking is challenging due to the varying climatic conditions in a solar PV system. Moreover,

Dip Coating of Passivation Layers for FA‐Cs‐Based Perovskite Solar Cells

Solar RRL, Volume 10, Issue 6, 29 March 2026.
A scalable dip‐coating strategy is developed for passivation layer deposition in methylammonium‐free perovskite solar cells. Through solvent engineering, using 2‐butanol as an orthogonal solvent for DATsO enables more effective passivation, uniform coating on substrates of different sizes, and minimal disruption to the underlying perovskite.

Twenty‐One Years of Global Atmospheric Chlorine Inventories From Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE‐FTS) Measurements

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract We present atmospheric chlorine inventories over 21 years (2004–2024) and five latitude bands (82–60°N, 60–30°N, 30°N–30°S, 30–60°S, 60–82°S) across altitudes from the surface up to 61 km. These inventories were calculated using the Atmospheric Chemistry Experiment‐Fourier Transform Spectrometer (ACE‐FTS) version 5.3 retrievals of the volume ...
