Description
Technical Field
The invention relates to a method for dividing an ITO glass conducting layer suitable for a large-area electrochromic window.
Background
The electrochromic intelligent window is a novel window capable of controlling heat in and out of a window body, can realize automatic color change or color change as required, and does not need to use an indoor sunshade curtain or an outdoor external sunshade barrier to shade or insulate heat. The glare and heat are controlled while the indoor space and the outdoor light are fused and communicated, and the energy consumption is effectively reduced. The ITO glass is used as an electrode in the manufacturing process of the electrochromic intelligent window, after a color-changing substance is added between the electrodes, current exists between the applied voltage electrodes, and the voltage drop occurs on the ITO surface, so that the voltage in different areas in an intelligent window device is uneven, the response time close to the electrode is short, the color change is fast, the response time far away from the electrode is long, and the color change is slow.
When the assembly method of the prototype device of the electrochromic smart window is performed, the common method is as follows:
dispensing a piece of conductive glass according to the following figure (as shown in figure 1), leaving an electrode area on one side of the glass, leaving a liquid filling port on a glue frame area, placing a 100 micron blocking agent on a glue line, covering another piece of conductive glass on the glue line, making the conductive surfaces of the two pieces of conductive glass opposite to each other, leaving an electrode area with the same width on the opposite side, curing the glue line by ultraviolet light, filling a color-changing solution from the liquid filling port, sealing by ultraviolet glue, and obtaining an electrochromic prototype device, wherein the front surface is shown in figure 2, and the side surface is shown in figure 23. And a circuit is led out from the conductive material of the electrode area and is connected with a voltage of 1.5V, so that the color change of the device can be realized. As is shown in figure 4. The above method is the most commonly used method for assembling electrochromic smart windows. Because the surface resistance of the ITO glass is low and can reach 3 omega/squr, the intelligent window device manufactured by the method has good color change effect, uniform color change and high and consistent response speed within a certain area. But when the area of the smart window needs to be enlarged continuously (e.g. more than 30 x 30 cm)2During the size), because the ITO conducting layer has voltage drop when the electrochromic window changes color, even the situation that the middle area can not change color occurs, the intelligent window changes color unevenly, and the response time is inconsistent, the voltage drop phenomenon on the ITO electrode limits the enlargement of the area of the electrochromic window. Moreover, research shows that the voltage drop on the electrode has a direct relation with the electrode area, and the larger the electrode area is, the more obvious the voltage drop on the electrode is.
