However, the stability of PNCs is significantly influenced by the solvents and electrolytes used, often leading to irreversible structural transformations and loss of intrinsic properties. This review emphasizes the importance of electrochemical and <em>in-situ</em> spectroelectrochemical techniques for characterizing PNCs’ redox properties, band structure, and halide defect sites that drive redox reactions and structural deformation.
