The search for novel multi-functional material has been on the rise for the past decades. These materials ought to possess flexible structures and tunable properties in order to be utilized for a variety of applications. Perovskite materials are predominantly used in solar cell applications due to their broad absorption spectrum, long carrier lifetime, and long transport distance of electrons and holes. Nevertheless, their unique and tunable properties allow for their utilization in a wide range of applications. In this work, a review on the application of perovskite materials in hydrogen production, supercapacitors, and optoelectronic devices is presented. The role of perovskite in the improvement of said applications is investigated, and future outlook and remarks are presented. This paper highlights the potential utilization of perovskite material outside the scope of photoelectric devices and solar cells.

Cu's electrical and thermal conductivity makes it a vital material in various industrial applications, but its susceptibility to oxidation under ambient conditions can compromise performance, particularly in the semiconductor industry. This study presents an innovative surface modification technique to inhibit the growth of native oxide on Cu prior to Ag coating to enhance a galvanic replacement (GR) reaction under good adhesion between Ag and Cu. Ag-coated Cu electrodes are effective in removing the surface oxide on Cu and acting as deformable and low-resistance Cu interconnects. The surface modification process utilizes vacuum ultraviolet (VUV) treatment in an ethanol atmosphere, forming a stable, hydroxylated surface layer that minimizes reoxidation before Ag deposition. X-ray photoelectron spectroscopy (XPS) confirmed the effective suppression of reoxidation, and scanning electron microscopy (SEM) revealed a homogeneous Ag coating with optimal surface coverage. This methodology significantly enhances the oxidation resistance of Cu.
