Summary: The electrodeposition of copper-selenium binary compounds on a gold electrode is investigated in ChCl-U deep eutectic solvent. The formation of Cu2Se is observed through cyclic voltammetry and potentiostatic deposition followed by stripping voltammetries, and is supported by X-Ray Photoelectron Spectroscopy. The electrochemical stability domain of the compound is limited by the oxidation of Se(0) and reduction of Cu(0). Copper is kinetically favored in the co-deposition process, and requires longer deposition times or more negative potentials to avoid pure copper deposition.

Summary: Advancements in supercapacitor performance are driven by both material design and device architecture adjustments. This study focuses on designing unique dead-weight free supercapacitors based on PANI electrochemically deposited on free-standing SWCNT films. The research shows that thin free-standing films of SWCNTs with deposited PANI are less prone to self-discharge, enabling higher gravimetric capacitance values.

Summary: SnS thin films were electrodeposited using one-step potentiostatic electrodeposition with different concentrations of triethanolamine complexing agent (TEA). The charge transfer coefficient, diffusion coefficient, and potential dependent cathodic rate were deduced from the electrochemical analysis. The addition of TEA influenced the surface morphology and the stoichiometry of the films. The band gap increased with TEA concentration, and the optimal properties were achieved at a specific concentration ratio.

Summary: In this work, solution-processed p-type nickel oxide (NiO) was used as the hole transport layer (HTL) in bulk heterojunction polymer solar cells (BHJ PSCs). Interlayer engineering of BHJ PSC was achieved by adjusting the potential regime and electrodeposition parameters. The resulting NiO nanostructures showed improved structural and electrochemical properties. The anodic potentiostatic electrodeposition method increased the photovoltaic performance of the PSCs compared to the cyclic voltammetry (CV) method.

Summary: The power of isoreticular chemistry was leveraged to design metal-organic frameworks (MOFs) with tunable optoelectronic properties. XDI linkers with different lengths and properties were used to construct a series of Zn-XDI MOFs, which exhibited distinct electrochromic properties. The thin films of these MOFs were grown on FTO substrates and characterized by XRD and SEM. The MOFs showed reversible redox events and changes in optical properties, depending on the linker length and redox state. Among them, Zn-PDI@FTO exhibited a record high coloration efficiency and excellent stability, suggesting its potential for practical applications.
