The electrochromic device further comprises electrodes, wherein the electrodes are arranged to supply power to the electrochromic device, and the electrochromic device is subjected to a fading effect through the change of current. The inner surface of the substrate includes a notch 300, the notch 300 being positioned opposite the electrode, the notch 300 having a depth less than the thickness of the substrate, the outer perimeter of the notch 300 and the perimeter of the substrate being sealed by an edge sealing material 135.
The substrate may be a planar glass. In one embodiment, the first transparent substrate 100 and the second transparent substrate 200 may also be curved glass.
The first conductive layer 105 and the second conductive layer 125 are conventional conductive layers, and the material includes one or more of Indium Tin Oxide (ITO), aluminum-doped zinc oxide (AZO), boron-doped zinc oxide (BZO), and fluorine-doped tin oxide (FTO).
Electrochromic stack 110 is a conventional electrochromic element including an electrochromic layer, an ion conducting layer, and an ion storage layer. In cooperation with first conductive layer 105 and second conductive layer 115 at forward and reverse voltages, can be reversibly switched between a colored state and a bleached state, with an overall resistance of about 2 to 10 ohms.
The bottom layer of the electrochromic stack 110 is an electrochromic layer disposed on the first conductive layer105, the first conductive layer 105 can be deposited by vacuum coating, evaporation coating, etc. to a thickness of 200 to 600 nm. The material is selected from tungsten oxide (WO)3) Molybdenum oxide (MoO)3) Niobium oxide (Nb)2O5) Titanium oxide (TiO)2) One or more of (a).
And then an ion conducting layer is arranged on the electrochromic layer and used for communicating ions between the electrochromic layer and the ion storage layer, the material is preferably metal lithium, and the film thickness is 10-300 nm. In order to improve the stability of lithium ions and increase the ionic porosity to improve the transmission rate, materials such as tantalum, niobium, cobalt, aluminum, silicon, phosphorus, boron and the like can be doped in the lithium thin film layer.
And finally, an ion storage layer is arranged on the ion conducting layer and used for storing lithium ions conducted from the electrochromic layer due to voltage, and the film thickness is 150-650 nm. The material of the ion storage layer is selected from nickel oxide (NiO)x) Iridium oxide (IrO)2) One or more of (a).
The electrode can be selected from conductive copper foil, copper-nickel solder strip, nickel-chromium solder strip and the like, a conductive narrow strip with high adhesive force can be formed on the surface of the conductive film through processes of vacuum coating, screen printing, dispensing, coating and the like, and then the electrode is connected with the first conductive layer 105 and the second conductive layer 125 through modes of conductive adhesive bonding, laser welding, elastic pressing and the like.
The notch 300 is opposite to the electrode, and when the electrochromic glass is actually used, a conductive wire is needed to connect the electrodes on the first conductive layer 105 and the second conductive layer 115 to form a loop. At this point, additional conductive wires can be collated and stored in close proximity into score groove 300, hiding the conductive wires while achieving planarization of the electrochromic glass structure.
In addition, in some cases, the electrodes may be directly covered by the notch 300 without using a conducting wire, the electrodes may directly extend out of the first substrate 100 and the second substrate 200, and then the electrodes may be connected by using a conducting wire to form a current-carrying loop.
The edge sealing material 135 is an all-inorganic or inorganic-metal slurry mixed material, and can be selected from one or more of the following oxidesThe method comprises the following steps: lithium, sodium, potassium, zinc, boron, aluminum, silicon, phosphorus, tin, bismuth. Lithium oxide (Li) is preferable2O), sodium oxide (Na)2O), potassium oxide (K)2O), zinc oxide (ZnO), boron oxide (B)2O3) Aluminum oxide (Al)2O3) Silicon dioxide (SiO)2) Phosphorus pentoxide (P)2O5) Tin oxide (SnO), bismuth oxide (Bi)2O3)。
Further, the notch 300 includes a drying body 600 therein for adsorbing moisture generated in the environment and between the substrates, so as to improve the lifetime and reliability of the electrochromic glass, and preferably, the drying body 600 may be a molecular sieve, silica gel, activated alumina, or the like. Optionally, there may be a plurality of notches 300 on each substrate, each notch 300 is filled with a dry body, and besides the notches 300 filled with the conductive wires, the additional notches 300 may further absorb surrounding moisture, further ensuring the lifetime of the electrochromic glass product.
Further, the electrodes include a first electrode 501 and a second electrode 502, the first electrode 501 is in electrical contact with the first conductive layer 105, the second electrode 502 is in electrical contact with the second conductive layer 115, the first electrode 501 is located in the groove of the inner surface of the first substrate 100, and the width of the first electrode 501 corresponds to the width of the groove of the inner surface of the first substrate 100. Therefore, by adjusting the width of the notch 600 on the first substrate 100, the width of the first electrode 501 can be adjusted accordingly, so as to increase the contact area between the first electrode 501 and the first conductive layer 105, increase the current transmission rate, and reduce the resistance.
Further, the electrochromic device further includes: an ion blocking layer 120; ion barrier layer 120 comprises silicon oxide or silicon aluminum oxide. Ion barrier layer 120 is disposed between second conductive layer 115 and second substrate 200, over second conductive layer 115. The ion barrier layer 120 uses a silicon (Si) or silicon aluminum (SiAl) target material having a thickness of 20 to 80nm and a composition of silicon oxide (SiO)x) Silicon aluminum oxide (SiAlO)x). The compactness of the aluminum is good, so that the migration of sodium and magnesium in the glass can be effectively blocked, and the adhesive force of the electrochromic film on the glass is improved, so that the electrochromic film cannot be peeled off.
Further, the electrochromic device further includes: an isolation layer 125; the isolation layer 125 is disposed between the ion blocking layer 120 and the second substrate 200. The isolation layer 125 has a film thickness of 100 to 1000nm, and may be made of one or more of titanium nitride, aluminum nitride, silicon nitride, and boron nitride. These materials have high transparency and high resistance, and can prevent current from dissipating after the device is powered on, and can protect functional layers deposited thereunder, such as electrochromic layers, ion conducting layers and the like, and reduce physical and chemical losses thereof.
As shown in fig. 2, after the ion barrier layer 120 and the isolation layer 125 are introduced, the second electrode 502 remains electrically connected to the second conductive layer 115, and the ion barrier layer 120 and the isolation layer 125 cover the second electrode 502. The second electrode 502 is now contacted by the conductive line 400 through the engraved 300 of the second substrate 200. The conductive line 400 is deposited into the engraved groove 300 of the second substrate 200. At this time, the structural top view of the electrochromic glass is shown in fig. 3, that is, the two sides of the substrate are the notches 300, and the first electrode 501 or the second electrode 502 is led out from the notches directly or through a wire according to different materials, and can start to work normally after being connected with a power supply. When the electrochromic glass is installed, the notch 300 can be blocked by the glass installation frame, and the notch 300 cannot be observed by a user during observation.
Further, a cavity 130 is also included, the cavity 130 being located between the first substrate 100 and the second substrate 200, i.e., any portion other than the electrochromic device, or a portion of the electrochromic device not in contact with the sealing material 135 or the second substrate 200. The cavity 130 is either evacuated or filled with an inert gas. The inert gas can prevent the film layer of the electrochromic device from being oxidized, and the service life of the electrochromic device is influenced, namely the hollow electrochromic glass is obtained. And the electrochromic glass is vacuumized, so that the sound insulation performance of the electrochromic glass can be further enhanced besides the protection of the electrochromic device film layer.
Electrochromic glazings can be reversibly cycled between a bleached state and a colored state when in use. In the bleached state, lithium ions are colored by applying a voltage at first conductive layer 105 and second conductive layer 115, passing through the ion conductive layer and into the electrochromic layer containing the electrochromic material. When the voltage potential applied at first conductive layer 105 and second conductive layer 115 is reversed, lithium ions leave the electrochromic layer, pass through the ion conducting layer, and return into the ion storage layer. Thereby, the device is switched to a bleached state. The electrochromic glazing can be switched not only back and forth between a bleached state and a colored state, but also to one or more intermediate tint states between the bleached state and the colored state, depending on the voltage control.
Further, the electrochromic layer in the electrochromic stack 110 includes a cathode coloring material therein, and the ion storage layer includes an anode coloring material therein. For example, the electrochromic layer may employ a cathodically coloring material, such as tungsten oxide; the ion storage layer may employ an anodic coloring material such as nickel oxide. That is, after lithium ions are separated from the ion storage layer, the ion storage layer also enters a colored state. Thereby, the electrochromic layer and the ion storage layer are combined and together reduce the amount of light transmitted through the stack.
Further, a polycrystalline structure of metal oxynitride deposition coating film can be used in the electrochromic layer, the film thickness is usually 150 to 650nm, and the material used specifically includes tungsten oxynitride (WO)xNy) Molybdenum oxynitride (MoO)xNy) Niobium oxynitride (NbO)xNy) Titanium oxynitride (TiO)xNy) Tantalum oxynitride (TaO)xNy) Depending on the nitrogen content, the parameters x and y vary accordingly. The molar number of nitrogen atoms in the electrochromic layer 110 is generally 0.05% to 20%, or 0.5% to 5%, or 0.5% to 10% of the total atomic molar number. Generally, the content of nitrogen exceeds 20%, the color of the deposited coating film can be deepened, which is caused by the color of the metal oxynitride, and the deepening of the color of the coating film can influence the light transmittance of the electrochromic glass in a fading state, so that the color change range of a finished device is reduced.
After metal oxide used by a conventional electrochromic layer is replaced by metal oxynitride, according to the difference of nitrogen content, nitrogen ions can replace oxygen ions in the original metal oxide, for example, tungsten is taken as an example, original W-O ionic bonds are partially replaced by W-N ionic bonds, so that the asymmetry of crystal lattices is caused, the acting force balance among original ions is destroyed, adjacent atoms deviate from the balance position, and the crystal distortion is caused. After the crystal is distorted, the interaction around the ion transport channel is reduced, thereby increasing the ion transport speed of the electrochromic layer. The nitrogen element is taken as a relatively stable element, and the stability of the metal compound is not affected by the introduction of the nitrogen element, so that the good stability is still maintained.
Similar to the electrochromic layer, the ion storage layer has a film thickness of 150 to 650nm and is selected from nickel oxynitride (NiO)xNy) Iridium oxynitride (IrO)xNy) Manganese oxynitride (MnO)xNy) Cobalt oxynitride (CoO)xNy) Tungsten nickel oxynitride (WNi)zOxNy) Iridium tungsten oxynitride (WIr)zOxNy) Tungsten manganese oxynitride (WMn)zOxNy) Tungsten-cobalt oxynitride (WCo)zOxNy) The mole number of nitrogen atoms in the film layer accounts for about 0.05 to 15 percent of the whole mole number of atoms. Nitrogen is further introduced into the conventional ion storage layer 120 to convert the conventional nickel oxide, iridium oxide material into nickel oxynitride, iridium oxynitride or cobalt oxynitride material, thereby improving the stability of the device during the color degradation due to the higher binding energy of the nitride relative to the oxide.
Further, still include: and the control module is connected with the electrodes and is positioned in the notch 300. Because the control module is small and can be stored in the notch 300, the control module can further integrate a series of control or communication units such as wireless, photosensitive, voice-operated, laser and the like, thereby integrating the electrochromic glass and the control unit thereof, being simple and convenient to operate, saving space and realizing planarization, lightness and thinness of the electrochromic glass product.
When the control module comprises a wireless unit, the electrochromic glass can be connected with a mobile phone, a computer, a panel, a center console and the like through Bluetooth or wifi and the control module in a wireless mode, and then the fading change of the electrochromic glass is controlled.
By implanting the photosensitive element control module, the voltage passing through the electrochromic device in the electrochromic glass can be automatically adjusted along with the light intensity so as to control the transmittance of the electrochromic glass.
Furthermore, a sound control unit can be additionally added to control the transmittance of electrochromism through voice recognition AI.
Further, a laser module can be added, and laser conduction is adopted to remotely control the transmittance of the electrochromic glass at an ultra-long distance.
By adding the different control modules, the electrochromic glass can be widely applied to automobile skylights, side windows of motor cars, side windows of airplanes, side windows of ship cruise ships, intelligent curtain walls, intelligent household appliances and the like.
Further, the etching grooves 300 are filled with a conductive material, and the conductive material is electrically connected to the electrodes.
The conductive material can be mixed with the drying body 600, or the conductive material can be spread after the drying body 600 is spread like the notch 300, at the moment, the electrode only needs to be contacted with the conductive material, or the electrode can be led out from the conductive material at the edge of the notch 300 after being led to the conductive material in the notch 300 through the lead 400, the conductive wire does not need to be arranged and wound and is placed in the notch 300, and the space in the notch 300 is more regular.
Further, the conductive material may be selected from at least one of the following materials: silver paste, carbon powder and copper paste for conducting current.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
