Controllable intermittent potential method for reflectance enhancement of silver deposition-based electrochromic cell

The reflectance of silver deposition-based electrochromic (EC) cells is affected by the surface structure of the silver deposits on the electrode. For the practical application of the EC cell, it is necessary to develop a method for the electrodeposition of silver on the ITO electrode for improving the reflectance of the silver deposition-based EC cell. Therefore, in this study, we propose a novel intermittent potential method, which is different from traditional constant potential coloring methods. The effectiveness of the proposed driving method was verified using a silver film with a high reflectance generated in three electrode-type EC cells. This study offers a potential method for improving the reflectance of silver deposition-based EC cells in a coloring state and provides valuable insights for the future development of practical high-reflectance type metal deposition-based EC devices.
