Description

Technical Field

[0001] The present invention relates to the technical field of electrochromic devices, in particular to a novel electrochromic device and a manufacturing method thereof. Background Art

[0002] Electrochromic devices can effectively change their optical properties by changing the external potential difference. This is mainly caused by the ion embedding / drag-out of the electrochromic material inside the electrochromic device. Through the transformation of the electrochromic device from the colored state to the faded state (transparent state), it can effectively realize a series of applications in smart windows (color-changing rearview mirrors, color-changing skylights); smart buildings (curtain wall glass, interior glass); and smart glasses (VR glasses, sunglasses).

[0003] However, due to the influence of the square resistance of the ITO conductive layer of the device, as the size of the electrochromic device gradually increases, the effective voltage distribution on the electrochromic device is uneven during use, that is, the effective voltage at the edge is greater than the effective voltage at the center. This not only causes the color depth at the center to be much smaller than the color depth at the edge when the product is used, that is, the color change degree is uneven; at the same time, when the electrochromic device changes color, the color change rate at the edge is also much higher than that at the center, that is, the color change rate is uneven. Summary of the invention

[0004] The purpose of the present invention is to provide a novel electrochromic device, by etching ITO glass, cutting off the ITO conductive area, and screen-printing conductive silver paste on the etched area, the high conductivity of the conductive silver paste is used to reduce the overall square resistance of the ITO glass, and at the same time, the small screen-printing width ensures that it cannot be detected by the human eye, ensuring the overall look and feel, and on this basis, an electrochromic device is prepared.

[0005] With the development of technology, screen printing technology has made significant progress. At present, the width of the screen printing line is less than 50μm, which is difficult for the human eye to observe. To this end, the present invention etches the ITO glass, cuts off the ITO conductive area, and screen prints the etched area with conductive silver paste. The high conductivity of the conductive silver paste is used to reduce the overall square resistance of the ITO glass. At the same time, the small screen printing width ensures that the human eye cannot detect it, ensuring the overall look and feel. On this basis, a large-size electrochromic device is prepared. After testing, its color change effect and color change rate are better than those of traditional large-size electrochromic devices.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1 , Figure 2 As shown, the present invention provides a technical solution:

[0034] A novel electrochromic device comprises a first substrate layer 11, a first conductive layer 12, a first silver paste layer 13, a first wiring layer 14, a packaging layer 15, an electrochromic layer 16, a second silver paste layer 17, a second wiring layer 18, a second conductive layer 19 and a second substrate layer 20;

[0035] Specifically, the first conductive layer 12 is disposed on the surface of the first base layer 11, the size of the first conductive layer 12 is the same as that of the first base layer, and the first conductive layer 12 is evenly provided with a plurality of first through grooves penetrating through the wall thickness thereof, and the first through grooves are arranged in a crisscross pattern;

[0036] The first silver paste layer 13 is filled in the first through groove;

[0037] The first wiring layer 14 is arranged at the edge of the first conductive layer;

[0038] The electrochromic layer 16 is disposed on the surface of the first conductive layer 12, and the size of the electrochromic layer 16 is smaller than the size of the first conductive layer 12;

[0045] During the research and development process, the present inventors have attempted to prepare electrochromic devices by reducing the overall square resistance of the ITO glass by screen-printing a conductive silver paste directly on the conductive layer (ITO) without etching the ITO. As a result, it was found that since the original electrochromic layer was very thin (200 μm) and the screen-printed conductive silver paste itself had a certain thickness (80-150 μm), the conductive silver pastes on the upper and lower substrates could easily contact each other and cause a short circuit, and the electrochromic device could not work.

[0046] Specifically, the first silver paste layer 13 divides the first conductive layer 12 into a plurality of rectangular first small units. To ensure that the overall square resistance is small enough, the length of the first conductive layer 12 / the length of the first small unit is ≥20, and the width of the first conductive layer 12 / the length of the first small unit is ≥20. To ensure the overall appearance of the device, the width of the first silver paste layer 13 is ≤100μm. Similarly, the second silver paste layer 17 divides the second conductive layer 19 into a plurality of rectangular second small units. The length of the second conductive layer 19 / the length of the second small unit is ≥20, the width of the second conductive layer 19 / the length of the second small unit is ≥20, and the width of the second silver paste layer 17 is ≤100μm.

[0047] Specifically, to ensure the overall transmittance of the electrochromic device, the visible light transmittance of the first substrate layer 11 and the second substrate layer 20 is greater than 90%; the thickness of the first conductive layer 12, the second conductive layer 19, the first silver paste layer 13 and the second silver paste layer 17 is less than 150nm; the thickness of the first substrate layer 11 and the second substrate layer 20 is less than 1.5mm; to ensure the color changing effect of the entire device, the thickness of the electrochromic layer 16 and the encapsulation layer 15 is less than 300μm; to ensure the color changing efficiency, the square resistance of the first conductive layer 12 and the second conductive layer 19 is less than 15 ohms, and the resistance of the first silver paste layer 13 and the second silver paste layer 17 is less than 5 milliohms; to ensure product stability and reliability, the encapsulation layer 15 has good water and oxygen barrier capabilities.
