Description
Technical Field
The invention relates to the field of energy-saving glass, in particular to time-division-driven special-shaped electrochromic glass, which is uniform, effective and rapid in voltage distribution and coloring speed of the glass by changing the shape of the glass, the arrangement mode of electrodes and a time-division control mode.
Background
In the prior art, the electrochromic glass with small area has very uniform color change, but the phenomenon of obvious uneven color change can occur in a large area, and the phenomenon greatly puzzles the application of the electrochromic device with large area.
With the application of electrochromic glass to building materials, the need for large area electrochromic glass is becoming more and more prominent. However, for large-area electrochromic glass, because the top conductive layer and the bottom conductive layer consume certain voltage drop, the problem that the effective driving voltage in the middle is insufficient and the effective driving voltage on the two sides is too high exists, so that the electrochromic glass is nonuniform in color change and slow in overall color change speed, the service life of a device can be influenced by the excessively high effective driving voltage on the two sides, and the problem is more remarkable when the area of the electrochromic glass is larger.
Disclosure of Invention
In order to solve the problems existing in the prior art: the effective driving voltage on two sides of the electrochromic glass with large area is too high, and the effective driving voltage in the middle is insufficient, so that the electrochromic glass is uneven in color change.
The invention aims to solve the technical problems that the shape structure, arrangement mode and voltage driving mode of the electrodes are changed, so that the electric effect distance between the two electrode ends is shortened, the effective driving voltage distribution on electrochromic glass is improved, and the color change of the large-area electrochromic glass is uniform.
The technical scheme adopted for solving the technical problems is as follows:
the invention provides a time-sharing driven special-shaped electrochromic glass, which is characterized by comprising the following components in percentage by weight: a special-shaped base material, wherein the base material is a special-shaped base material,
a first conductive layer disposed on the profiled substrate;
a first electrochromic layer and a bottom electrode disposed on the first conductive layer;
an ion conducting layer, a second electrochromic layer, and a second conducting layer disposed on the first electrochromic layer;
a top electrode disposed on the second conductive layer;
and forward voltage is applied between the top electrode and the bottom electrode to drive the electrochromic glass to change color, and reverse voltage is applied to drive the electrochromic glass to change color.
In some embodiments, the bottom electrodes are distributed outside the different side lengths and centered along the side length direction, and the number of the bottom electrodes is equal to the number of the side lengths;
the top connection electrodes are distributed at the corner parts of each abnormal top angle, and the number of the top connection electrodes is equal to the number of the side lengths.
In some embodiments, the top electrode and/or the bottom electrode are stripe-shaped.
In some embodiments, the profiled substrate comprises a regular triangle or a regular pentagon or a regular heptagon.
Further, the one top electrode and the one bottom electrode are a pair of electrodes, and when the special-shaped base material is in a regular triangle shape, three pairs of electrodes are arranged; when the special-shaped base material is a regular pentagon, five pairs of electrodes are arranged; when the special-shaped base material is in a regular heptagon shape, seven pairs of electrodes are arranged.
In some embodiments, each of the top-connected electrodes is in disconnection with the bottom-connected electrode.
In some embodiments, the bottom electrode length is 40% to 80% of the side length.
In some embodiments, the top electrode length is 20% to 60% of the side length.
In some embodiments, each pair of the electrodes is configured to be time-shared, alternating drive for a time period in the range of 0.1 to 600 seconds.
The invention provides a special-shaped electrochromic device, wherein a plurality of pairs of top electrodes and bottom electrodes are distributed on the middle of each side length and the corners of the top end in a crossed manner through the special-shaped shape of a polygon, so that an annular passage is formed from inside to outside after the special-shaped electrochromic device is electrified; when the electrode driving mode is started, the annular passage on the outer side applies positive and negative potential differences to the inner side, so that the distribution of the effective driving voltage of the electrochromic glass can be greatly improved, and the large-area electrochromic can be more uniformly and rapidly carried out; each section of side electrode and corner electrode are driven in turn in time sharing, so that the electric leakage of the device is controlled.

The following is a specific embodiment, and the technical scheme of the invention is further specifically described with reference to the accompanying drawings:
embodiment one:
the invention provides a time-sharing-driven special-shaped electrochromic glass, which is shown as a rectangular electrochromic device 1 in fig. 1 and 2, wherein the rectangular electrochromic device 1 is used for simply describing the preparation flow and the film structure of the special-shaped electrochromic glass; a first conductive layer 5 is prepared on the substrate, a first electrochromic layer 6 is prepared on the first conductive layer 5 leaving an aperture to the bottom electrode, an ion conductive layer 7 is prepared on the first electrochromic layer 6, a second electrochromic layer 8 and a second conductive layer 9. The widths of the first electrochromic layer 6, the ion conducting layer 7 and the second electrochromic layer 8 are consistent with the width of the second conducting layer 9. A strip-shaped bottom electrode 2 is prepared on the empty position of the first conductive layer 5, and a strip-shaped top electrode 3 is arranged at the edge of the second conductive layer 9 in the direction away from the strip-shaped bottom electrode 2.
An equilateral triangle electrochromic device with a side length of 10 cm is shown in fig. 4:
the preparation flow and process of the polygonal electrochromic device are explained by way of example only;
depositing a first conductive layer 5 film on the substrate 4 using an equilateral triangle transparent glass substrate 4; depositing a first electrochromic layer 6 film on the first conductive layer 5 film by adopting a vacuum coating process; as shown in fig. 3: the first electrochromic layer 6 film does not cover the bottom electrode stripe gaps 16, and the common process is that the bottom electrode is exposed by laser etching; three bottom electrode strip connecting vacancies 16 are arranged on the film of the first conductive layer 5, and the bottom electrode strip connecting vacancies 16 are attached to the edge of the side length of the glass substrate 4; the shape of the first conductive layer 5 is shown as a film layer 17 in fig. 4, a vacuum coating process is adopted to sequentially deposit a film of the ion conductive layer 7, a film of the second electrochromic layer 8 and a film of the second conductive layer 9 on the first electrochromic layer 6, and the film layer structure is shown as fig. 2.
The first electrochromic layer 6 and the second electrochromic layer 8 have ion complementation relationship, so that linkage color change can be realized; the first electrochromic layer 6 obtains ions under the action of the electric potential to reduce the light transmittance, and the second electrochromic layer 8 loses ions to reduce the light transmittance, so that the light transmittance change range of the electrochromic device is enlarged.
As shown in fig. 3, the strip-shaped bottom electrode strips (13, 14, 15) and the strip-shaped top electrode strips (10, 11, 12) are led out from the empty spaces 16 of the bottom electrode strips and the outer sides of the top ends of the second conductive layers 9, which are reserved by the first conductive layers 5, by adopting a laser trimming or laser scribing process.
The first conductive layer 5 and the second conductive layer 9 are conventional conductive layers, and the material comprises one or more of Indium Tin Oxide (ITO), aluminum doped zinc oxide (AZO), boron doped zinc oxide (BZO) and fluorine doped tin oxide (FTO), and the thickness is 150-650 nm.
The first electrochromic layer 6 is a polycrystalline metal oxynitride deposited film with a thickness of 150 to 650nm, and the material used specifically includes tungsten oxynitride (WO x N y ) Molybdenum oxynitride (MoO) x N y ) Niobium oxynitride (NbO) x N y ) Titanium oxynitride (TiO) x N y ) Tantalum oxynitride (TaO) x N y ) One or more of the following.
Ion conducting layer 7 is selected from lithium silicon oxynitride (LiSi) z O x N y ) Tantalum lithium oxynitride (LiTa) z O x N y ) Lithium niobium oxynitride (LiNb) z O x N y ) Cobalt lithium oxynitride (LiCo) z O x N y ) Lithium aluminum oxynitride (LiAl) z O x N y ) Lithium phosphorus oxynitride (LiP) z O x N y ) Boron lithium oxynitride (LiB) z O x N y ) In (c) a plurality of the above,
the second electrochromic layer 8 has a thickness of 150 to 650nm and is made of a material selected from nickel oxynitride (NiO) x N y ) Iridium oxynitride (IrO) x N y ) Manganese oxynitride (MnO) x N y ) Cobalt oxynitride (CoO) x N y ) Tungsten nickel oxynitride (WNi) z O x N y ) Tungsten iridium oxynitride (WIr) z O x N y ) Tungsten manganese oxynitride (WMn) z O x N y ) Tungsten cobalt oxynitride (WCo) z O x N y ) The mole number of nitrogen atoms in the film layer accounts for about 0.05-15% of the mole number of the whole atoms.
In the above materials, the parameters of x, y and z are correspondingly changed according to the difference of nitrogen content.
As shown in fig. 4, the triangular electrochromic device 18 has 6 electrode bars, which are divided into 3 top electrode bars and 3 bottom electrode bars; the top electrode strips and the bottom electrode strips are in disconnection distribution, and the disconnection distribution mode is as follows: the electrode strips are not contacted with each other and are distributed at intervals; the two sides of each bottom electrode strip are top electrode strips, the two sides of each top electrode strip are bottom electrode strips, and the top electrode strips are not connected with the bottom electrode strips.
One top electrode bar and one bottom electrode bar of the triangular electrochromic device 18 form a group of electrode drives, and three top electrode bars and three bottom electrode bars are combined to form three groups of electrode drives; three groups of electrodes time-sharing driving mode: the three groups of electrode strips alternately add the same-time same-direction pulse voltages. Only one set of electrode drives is pulsed with the same direction at a time, for example: firstly, pulse voltage is applied to a group of electrode drives for 10 seconds, and then the electrode drives are disconnected; the other group of electrode drives are added with pulse voltage for 10 seconds while being disconnected, and then disconnected; the third group of electrode drives are simultaneously applied with pulse voltage of 10 seconds while the third group of electrode drives are disconnected, and the same-direction pulse voltage is applied to the three groups of electrode drives in turn, and as the top electrode strips and the bottom electrode strips of different groups are respectively arranged at the edge positions of the side length and the edge of the triangular electrochromic device 18, the electrochromic device 16 changes color from three sides, then changes color evenly and rapidly towards the middle until the whole electrochromic glass is evenly changed.
The triangle electrochromic glass electrode in the embodiment is driven by a forward voltage to change the color of the electrochromic glass, and the color of the transparent triangle electrochromic glass gradually darkens until the transparent triangle electrochromic glass becomes non-transparent glass; the application of a reverse voltage drives the electrochromic glass to fade, and the electrochromic glass will fade gradually until it becomes transparent.
Because of the regular triangle, the distance between the top of the top electrode and the middle position opposite to the bottom electrode strip is the largest, and the top extends to two sides and gradually approaches to the opposite electrode strips; after the voltage is applied, the potential in the electrochromic device also presents a shortened effective distance which extends from the bent top to two sides and spans at the same time, so that the distribution of the effective driving voltage on the electrochromic glass is improved, and the distribution is more uniform. In addition, the distance of effective driving voltage distribution becomes smaller, so that the voltage drop consumed by the driving voltage on the conductive layer is greatly reduced, and even if lower driving voltage is used, enough effective driving voltage can be maintained to effectively drive the middle part of the electrochromic glass, materials near the electrode strips are prevented from being in a state with higher driving voltage for a long time, the materials are prevented from aging too fast, and the service life of the electrochromic glass is prolonged.
