<p>A reversible electrochemical mirror device includes a substantially transparent first electrode (106) having a textured surface, and a second electrode (110) which may be distributed in localized areas. An electrolytic solution (112), disposed between the first and second electrodes, contains ions (116) of a metal which can electrodeposit on the electrodes. A negative electrical potential applied to the first electrode causes deposited metal to be dissolved from the second electrode into the electrolytic solution and to be electrodeposited from the solution onto the textured surface of the first electrode, thereby affecting the reflectivity of the device for electromagnetic radiation. Because of the textured surface, light striking the first electrode is diffusely reflected, making the device desirable for architectural and automotive glass applications. A surface modification layer (108) applied to the first electrode ensures that the electrodeposit is substantially uniform. A positive electrical potential applied to the first electrode causes deposited metal to be dissolved from the first electrode and electrodeposited from the solution onto the second electrode, thereby decreasing the reflection of radiation by the device.</p> |
