Nickel(II) Oxide is a face-centered cubic crystalline material with broad applications in ceramics, energy storage, and photovoltaics. Traditionally used in frits, ferrites, and porcelain glazes, NiO has emerged as a high-performance hole-transport layer (HTL) in perovskite solar cells, offering conductivity of 2.45 × 10⁻² mS·cm⁻¹ and hole mobility of 7.01 × 10⁻³ cm²·V⁻¹·s⁻¹, enabling inverted cells with 22.62% PCE. In supercapacitors, NiO nanopowders deliver 605 F·g⁻¹ at 5 A·g⁻¹ with reliable cycling stability. As a cathode in paper-based batteries, NiO demonstrates strong electrochemical performance with current density of 1.94 mA·cm⁻² and power density of 1 mW·cm⁻².
