Abstract
A laminated glass pane assembly with electrically controllable reflectivity, especially for controlling the entry of sunlight and solar heat into vehicles or buildings. The laminated glass pane comprises a first glass pane, an electroreflective functional layer made of an alloy of the hydride of a rare earth metal and magnesium, an antioxidation layer made of a proton-conducting transparent oxide or fluoride, an anhydrous proton-conducting solid electrolyte, a proton storage layer, a transparent conducting coating, and a second glass pane.

- a transparent conducting coating;
- and
- a second glass pane.
A method for making a laminated glass pane assembly with electrically controllable reflectivity, comprising:
- applying an electroreflective functional layer consisting of an alloy of the hydride of a rare earth metal and magnesium to a first glass pane;
- applying an antioxidation layer consisting of a proton-conducting transparent oxide or fluoride to the electroreflective functional layer;
- providing a second glass pane with a transparent conductivity coating;
- applying a transparent conductivity coating with a proton storage layer;
- providing an anhydrous proton-conducting solid electrolyte between the proton storage layer and the antioxidation layer;
- attaching an electrode to the transparent conductivity coating and to the electroreflective functional layer;
- and
- adhering the two glass panes together so that said coating and layers are between the glass panes.
A method of controlling radiation through a multiple glass paned assembly, comprising:
- applying an electroreflective functional layer consisting of an alloy of the hydride of a rare earth metal and magnesium to a first glass pane;
- providing a second glass pane with a transparent conductivity coating;
- applying a transparent conductivity coating with a proton storage layer;
- providing an anhydrous proton-conducting solid electrolyte between the proton storage layer and the antioxidation layer;
- adhering the two glass panes together so that said coating and layers are between the glass panes;
- decreasing the reflectivity of the assembly by activating the proton storage layer to release positively charged protons that migrate to the functional layer which decreases the reflective state of properties of the functional layer with the capability of increasing the reflectivity by activating the functional layer to form the protons that migrate to the proton storage layer.
