Chelating Coordination Regulates Perovskite Crystallization and Defect Passivation in Sn–Pb Perovskite Solar Cells

open access: yesSmall, Volume 22, Issue 27, 14 May 2026.
A chelating coordination strategy using ethylenediamine diacetate (EDDA) is introduced to regulate crystallization and passivate defects in Sn–Pb perovskite solar cells. Interfacial coordination at both buried and top surfaces suppresses Sn2+ oxidation, reduces defects, and enhances charge extraction, enabling over 23% efficiency with improved voltage,

Development of Maximum Power Point Tracking (MPPT) Algorithms for Solar Energy Conversion

open access: yesJournal of Multidisciplinary Research and Technology
Maximum power point tracking is essential in photovoltaic energy conversion because the operating point that yields maximum power varies continuously with solar irradiance, cell temperature, and load dynamics. Conventional tracking methods such as perturb and observe and incremental conductance are widely used due to their simplicity, but they may ...
