Abstract: Disclosed are methods and systems of reversible metal electrodeposition (RME) devices with applications in dynamic smart windows. Embodiments use a RME device that includes two transparent substrates that sandwich a working electrode, counter electrode, and an electrolyte solution. Embodiments apply a pulsed voltage to the RME device that causes electrochemical deposition of metal ions from the electrolyte solution to create a metallic film on the working electrode. The metallic film results in reduced light transmittance of the RME device.
