Referring to fig. 1 to 3 together, fig. 1 is a schematic structural layer diagram of an improved front electrochromic module, fig. 2 is a schematic structural layer diagram of a bonding region of the improved front electrochromic module, and fig. 3 is a schematic structural sectional view at a-a in fig. 2. Wherein, in the technical scheme before improving, its electrochromic module includes range upon range of setting in proper order: the solar cell comprises an upper substrate 1, an upper ITO 2, a discoloring layer 3, an electrolyte layer 4, an ion storage layer 5, a lower ITO 6, a lower substrate 7, an upper metal wire 8 and a lower metal wire 9; in addition, for the convenience of wire leading (binding), the upper metal trace 8 and the lower metal trace 9 are generally connected through a silver paste 95 (not shown), that is, the lower metal trace 9 is guided to one side of the upper metal trace 8, so as to achieve the purpose of single-side wire leading.

Specifically, the first conductive layer 120 and the second conductive layer 140 are spaced apart from each other on the same surface of the first substrate 110, i.e., the first conductive layer 120 and the second conductive layer 140 are coplanar. A gap 1024 is formed between the first conductive layer 120 and the second conductive layer 140, and an insulating filler may be disposed in the gap 1024, which is not limited herein.

Optionally, an electrochromic layer 131 (i.e., an EC layer) is disposed on the first conductive layer 120; an ion storage layer 132 (i.e., an IC layer) is disposed on the second conductive layer 140. The electrolyte layer 133 covers the electrochromic layer 131 and the ion storage layer 132 at the same time, and the absorption of light is changed by the migration of electrons (charged particles) in the electrolyte layer 133, so that the color change effect of the electrochromic module is realized. Wherein the electrochromic layer 131 is disposed coplanar with the ion storage layer 132. The shape of the projection of the electrochromic layer 131 on the first substrate 110 is matched with the shape of the projection of the first conductive layer 120 on the first substrate 110; the shape of the projection of the ion storage layer 132 on the first substrate 110 is adapted to the shape of the projection of the second conductive layer 140 on the first substrate 110. The term "shape-fitting" as used herein means that the shapes and areas are the same or substantially the same.

Alternatively, the material of the electrochromic layer 131 may be selected from organic polymers (including polyaniline, polythiophene, etc.), inorganic materials (prussian blue, transition metal oxides such as tungsten trioxide), and organic small molecules (viologen), etc. In the embodiment of the present application, the electrochromic layer 131 is exemplified as an organic polymer, and the electrochromic layer 131 may be a solid or gel material. Alternatively, the ion storage layer 132 and the electrochromic layer 131 may be formed on the conductive layer by doctor blade coating, and the electrolyte layer 133 may also be formed by doctor blade coating or drip irrigation, etc., which are not detailed herein within the understanding of those skilled in the art.

Optionally, the second substrate 150 covers the electrolyte layer 133. The sealant frame 160 surrounds the electrochromic layer 131, the ion storage layer 132, and the electrolyte layer 133.

The metal trace 180 in the embodiment of the present application includes a first metal trace 181 and a second metal trace 182; the first metal trace 181 is disposed on the first conductive layer 120 and electrically connected to the first conductive layer 120; the second metal trace 182 is disposed on the second conductive layer 140 and electrically connected to the second conductive layer 140. The metal trace 180 includes but is not limited to a multi-layer trace structure such as a silver paste line, a copper plated layer, an aluminum plated layer, or a molybdenum aluminum molybdenum layer. In order to make the electrochromic module have a faster color change speed, the sheet resistance of the first conductive layer 120 and the second conductive layer 140 is set to be 10-150 ohms, such as 10 ohms, 20 ohms, 40 ohms, 50 ohms, 80 ohms, 100 ohms, 120 ohms, 150 ohms, and so on; the sheet resistance of the first metal trace 181 and the second metal trace 182 may be 0.05-2 ohms, and may specifically be 0.05 ohms, 0.06 ohms, 0.1 ohms, 1.2 ohms, 1.5 ohms, 2 ohms, and the like, which is not limited herein. The coloring speed of the electrochromic module can be between 3-20s, the fading speed between 3-15s, or faster. It should be noted that the terms "first", "second" and "third" in the embodiments of the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

Optionally, with reference to fig. 5, in the present embodiment, the first metal trace 181 and the second metal trace 182 are embedded in the rubber frame 160, so as to achieve physical isolation from the electrochromic layer 131, the ion storage layer 132, and the electrolyte layer 133, and prevent the electrochromic layer 131, the ion storage layer 132, and the electrolyte layer 133 from chemically corroding the first metal trace 181 and the second metal trace 182.

Optionally, referring to fig. 4 and fig. 6 together, fig. 6 is a schematic partial sectional view at C-C in fig. 4; the electrochromic module 100 in this embodiment further includes a flexible circuit board 183, where the flexible circuit board 183 is connected to the first trace leading-out end 1811 of the first metal trace 181 and the second trace leading-out end 1821 of the second metal trace 182, and the flexible circuit board 183 is configured to connect the electrochromic module to a control circuit board (specifically, a control circuit board of an electronic device or a self-contained chip structure, which is not specifically limited herein). It should be noted that in some other embodiments, the electrochromic module 100 may also be a structure that does not include metal traces, and the first conductive layer 120 and the second conductive layer 140 are directly connected to the control circuit board through the flexible circuit board.

The current sequence of the electrochromic module in this embodiment is: the power supply positive electrode (or negative electrode) -FPC 183-first wire leading-out end 1811-first metal wire 181-first conductive layer 120-electrochromic layer 131-electrolyte layer 133-ion storage layer 132-second conductive layer 140-second metal wire 182-second wire leading-out end 1821-FPC 183-power supply negative electrode (or positive electrode). The stacked structure adopts a coplanar design, and the current loop also becomes a transverse flow. In order to prevent the device from being broken, the conductive layer structure needs to be separated into two separate regions (the second conductive layer 140 and the first conductive layer 120) from the middle partition, and the conductive layer structure is not needed for the upper substrate (i.e., the second substrate 150) to only protect.

Compared with the technical scheme before improvement, the electrochromic module provided by the embodiment of the application has the advantages that the electrochromic layer and the ion storage layer are arranged on the same layer, and a conductive layer structure is eliminated, so that the structure of a conducting area can be omitted, the automatic production is facilitated, the productivity is improved, the adverse risk caused by processing can be reduced, and the yield of products is improved; in addition, the whole thickness of the electrochromic module can be reduced by 50-100 μm due to the elimination of a conducting layer structure.

In the embodiment, the first conductive layer 120 (including the electrochromic layer 131 disposed thereon) and the second conductive layer 140 (including the ion storage layer 132 disposed thereon) are disposed on the left and right portions of the first substrate 110 in the drawing, and may have an effect of a single left-side color change, a single right-side color change, or a left-side and right-side alternate color change. In still other embodiments, the first conductive layer 120 and the second conductive layer 140 may have other relative positions.

Referring to fig. 7 to 9, fig. 7 is a schematic overall structure diagram of another embodiment of an electrochromic module of the present application, and fig. 8 is a schematic cross-sectional structure diagram of a position D-D of the electrochromic module in the embodiment of fig. 7; FIG. 9 is a schematic view of another structure of an electrochromic module. Unlike the previous embodiments, in the embodiment shown in fig. 8, the first conductive layer 120 is at least partially disposed around the second conductive layer 140. In the embodiment shown in fig. 9, the second conductive layer 140 is at least partially disposed around the first conductive layer 120. Wherein the shape of the projection of the electrochromic layer 131 on the first substrate 110 is adapted to the shape of the projection of the first conductive layer 120 on the first substrate 110; the shape of the projection of the ion storage layer 132 on the first substrate 110 is adapted to the shape of the projection of the second conductive layer 140 on the first substrate 110.

The electrochromic module in the embodiments of fig. 8 and 9 may form a ring shape (in fig. 8, the areas corresponding to the first conductive layer 120 and the electrochromic layer 131 located at the outer periphery) and a middle large area (in fig. 9, the areas corresponding to the first conductive layer 120 and the electrochromic layer 131 located at the middle part) to change color. Of course, in some other embodiments, there may be other corresponding relationships between the first conductive layer 120 and the second conductive layer 140, so as to form different color-changing regions and effects, and those skilled in the art can design the color-changing regions and effects by themselves under the technical guidance of the present application, and they are not listed and described in detail herein. In this embodiment, reference may be made to the related description of the foregoing embodiments for the material, arrangement relationship, and the like of the first substrate, the first conductive layer, the second conductive layer, the electrochromic layer, the ion storage layer, the electrolyte layer, and the second substrate.

Optionally, referring to fig. 10, fig. 10 is a schematic structural diagram of another embodiment of the electrochromic module of the present application, in which a water and oxygen barrier layer 170 is disposed on at least one of an outer surface of the second substrate 150 facing away from the electrolyte layer 133 and an outer surface of the first substrate 110 facing away from the first conductive layer 120. In the illustration of the present embodiment, a water and oxygen barrier layer 170 is disposed on an outer surface of the first substrate 110 away from the first conductive layer 120 for illustration, and certainly, in some other embodiments, a water and oxygen barrier layer 170 may be disposed on an outer surface of the second substrate 150 away from the electrolyte layer 133, and a water and oxygen barrier layer 170 may be disposed on both an outer surface of the second substrate 150 away from the electrolyte layer 133 and an outer surface of the first substrate 110 away from the first conductive layer 120.

The material of the water-oxygen barrier layer 170 is selected from any one of a dense metal oxide layer, an inorganic non-metal layer, or a composite layer formed by stacking materials and inorganic materials. Such as alumina, silicon oxide, titanium oxide, a synthetic resin material, or a laminated composite structure of a plurality of materials, or the like. The water-oxygen barrier layer 170 may be formed on the surface of the first substrate 110 by spraying, screen printing, physical vapor deposition, or the like. The water oxygen barrier layer 170 is used to isolate external water vapor and air, and since the electrochromic material in the electrochromic module is sensitive to water oxygen and is easily ineffective, it needs to be protected by the water oxygen barrier layer. The water-oxygen barrier layer 170 in this embodiment has a water vapor transmission rate WVTR of less than 0.02 g/m/day. The water vapor permeation direction of the water oxygen barrier layer 170 in the embodiment of the present application is a physical characteristic that the water oxygen barrier layer 170 permeates from one side surface of the water oxygen barrier layer 170 in the thickness direction to the opposite side surface. The test conditions were ambient temperature 20 ℃ and relative humidity 100%. In addition, in some other embodiments, the water oxygen barrier layer 170 may also be a structure with a substrate and a sprayed water oxygen barrier material disposed on the substrate, and is not limited herein.

Optionally, referring to fig. 11, fig. 11 is a schematic structural diagram of another embodiment of the electrochromic module of the present application, in which an appearance film layer 190 is disposed on at least one of an outer surface of the second substrate 150 facing away from the electrolyte layer 133 and an outer surface of the first substrate 110 facing away from the first conductive layer 120. In the embodiment, the illustration and the appearance film 190 are disposed on the outer surface of the first substrate 110 away from the first conductive layer 120, that is, on the outer surface of the water-oxygen barrier layer 170.

The appearance film layer 190 may include a carrier plate, and at least one of an ink layer, an optical coating layer, and a texture layer stacked on the carrier plate. In some other embodiments, the appearance film layer 190 may be a plating layer structure that is not included in the carrier plate, but is plated on the outer surface of the water oxygen barrier layer 170, which is not limited herein. The electrochromic module 100 can display the display effect of the appearance film layer 190 and the color-changing material layer in a superposition manner. In addition, when the appearance film layer 190 itself can also be of a gradual change effect, and when the appearance film layer 190 itself is of a gradual change effect, the appearance film layer can be overlaid with the color-changing material layer to present a richer appearance effect. It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present application are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In addition, in other embodiments, a water and oxygen barrier layer and an appearance film layer may be further disposed on one side of the second substrate 150. In the electrochromic module structure in this embodiment, a conductive layer is omitted, so that the design of the substrate without the conductive layer is more flexible, for example, the second substrate 150 can be directly replaced by a water-oxygen barrier film or an appearance film.
