With an innovative combination of high electrical conductivity, optical transparency, and mechanical flexibility that outperforms conventional material like indium tin oxide (ITO), silver nanowires (AgNWs) have become the leading option for next-generation transparent conductors in devices such as flexible displays, OLEDs, and solar cells.. This review offers a comprehensive overview of the polyol process, the dominant and most widely used technique for synthesizing AgNWs. Despite the advantages, achieving high-quality AgNWs remains a challenge, necessitating precise control over numerous variables. Discussed the critical roles of chemical reagents in controlling the nucleation and anisotropic growth of the nanowires in details, including roles of silver source, the poly(vinyl pyrrolidone) (PVP) as a facet-selective capping agent, and various mediating halide salts. The review also give a detailed account of the impact of physical process parameters, including reaction temperature, time, and stirring rate, on the reaction kinetics and final morphology of the produced product. Achieving high-quality AgNWs requires a delicate balance of these chemical and physical factors to achieve the desired aspect ratio and yield for advanced applications.
