Introduction Click to copy section linkSection link copied! Due to the abundant sodium reserves in the Earth’s crust and the similar electrochemical activity of sodium and lithium ions, sodium-based electrochemical energy storage systems (batteries and supercapacitors) hold significant promise for large-scale energy storage and grid development. With this motivation, most scientific and engineering efforts have focused on developing industrially applicable electrode materials.

Recombination Resistance Identification through Current-Voltage Curve Reconstruction in Perovskite Solar Cells Perovskite solar cells (PSCs) have demonstrated remarkable advancements in efficiency and stability, yet fully understanding the dynamic processes governing their performance remains a challenge. Impedance Spectroscopy (IS) offers a powerful means to characterize PSCs over a wide range of time scales, revealing insights into the internal electronic and ionic processes.

Chemically driven dimensionality modulation on hybrid tin (II) halide perovskites microcrystals Lead-free perovskites can change their lattice arrangement with the synthesis conditions, such as concentration, temperature, solvents, and monovalent cation length. This effect, often described as dimensionality modulation, can be exploited to develop new materials with better optical properties than their three-dimensional counterpart.
