Description
Technical Field
The invention relates to the field of energy-saving glass, in particular to special-shaped electrochromic glass capable of being driven in a time-sharing manner, which obtains uniform, effective and rapid voltage distribution and glass coloring speed by changing the shape of the glass, the arrangement mode of electrodes and the time-sharing control mode.
Background
In the prior art, the electrochromic glass with a small area has very uniform color change, but the phenomenon of obvious nonuniform color change can occur in a large area, and the phenomenon greatly troubles the application of large-area electrochromic devices.
With the application of electrochromic glass in building materials, the demand of large-area electrochromic glass is more and more prominent. However, for large-area electrochromic glass, because the top conducting layer and the bottom conducting layer can consume a certain voltage drop, the problem that the middle effective driving voltage is insufficient and the effective driving voltages at two sides are too high exists, so that the electrochromic glass has nonuniform color change and slow overall color change speed, the service life of a device can be influenced by the too high effective driving voltages at two sides, and the problem is more obvious 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 at two sides of the large-area electrochromic glass is too high, and the effective driving voltage in the middle is insufficient, so that the electrochromic glass is not uniform in color change.
The invention aims to solve the technical problems that the electrical effect distance between the end parts of two electrodes is shortened and the effective driving voltage distribution on the electrochromic glass is improved by changing the shape structure, the arrangement mode and the voltage driving mode of the electrodes, so that the large-area electrochromic glass is uniformly discolored.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the invention provides special-shaped electrochromic glass capable of being driven in a time-sharing manner, which is characterized by comprising the following components: a special-shaped base material is formed by a plurality of layers,
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 arranged on the first electrochromic layer;
a top contact electrode disposed on the second conductive layer;
and a forward voltage is applied between the top electrode and the bottom electrode to drive the electrochromic glass to discolor, and a reverse voltage is applied to drive the electrochromic glass to discolor.
In some embodiments, the bottom electrodes are distributed outside the lengths of the edges of the different shapes, and are centered along the length direction of the edges, and the number of the bottom electrodes is equal to the number of the edges;
the top contact electrodes are distributed at the corner parts of the different vertex angles, and the number of the top contact electrodes is equal to the number of side lengths.
In some embodiments, the top-contacting electrode and/or the bottom-contacting electrode are strip-shaped.
In some embodiments, the contoured substrate comprises a regular triangle, or a regular pentagon, or a regular heptagon.
Furthermore, the top electrode and the 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 provided; when the special-shaped base material is regular pentagon, five pairs of electrodes are arranged; when the special-shaped base material is regular heptagon, seven pairs of electrodes are provided.
In some embodiments, each of the top contact electrodes is disposed in a disconnected manner from the bottom contact electrode.
In some embodiments, the bottom-connected electrode length is 40% to 80% of the side length.
In some embodiments, the top-contact electrode length is 20% to 60% of the side length.
In some embodiments, each pair of said electrodes is configured to be driven in turn at a time division, the driving time ranging from 0.1 to 600 seconds.
The invention provides a special-shaped electrochromic device, which is characterized in that multiple pairs of top electrodes and bottom electrodes are distributed on the middle and top corners of each side length in a crossed manner through the special 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 at the outer side applies positive and negative potential difference to the inner part, so that the distribution of effective driving voltage of the electrochromic glass can be greatly improved, and large-area electrochromic is performed more uniformly and more quickly; each section of side length electrode and each section of corner electrode are driven in turn in a time-sharing mode, 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:
the first embodiment is as follows:
the invention provides special-shaped electrochromic glass capable of being driven in a time-sharing manner, as shown in figures 1 and 2, a rectangular electrochromic device 1 is shown, and the preparation process and the film layer structure of the special-shaped electrochromic glass are simply explained by using the rectangular electrochromic device 1; preparing a first conductive layer 5 on the substrate, preparing a first electrochromic layer 6 on the first conductive layer 5 and leaving a space to a bottom electrode, preparing an ion conductive layer 7, a second electrochromic layer 8 and a second conductive layer 9 on the first electrochromic layer 6.

using an equilateral triangular transparent glass substrate 4, depositing a first conductive layer 5 film on the 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 strip vacant sites 16, and the common process is that the bottom electrode is exposed by laser etching; three bottom electrode strip vacancies 16 are formed on the film of the first conductive layer 5, and the bottom electrode strip vacancies 16 are attached to the edge of the side length of the glass substrate 4; the first conductive layer 5 is shaped as a film 17 in fig. 4, and an ion conductive layer 7 film, a second electrochromic layer 8 film and a second conductive layer 9 film are sequentially deposited on the first electrochromic layer 6 by a vacuum coating process, and the film structure is shown in fig. 2.
The first electrochromic layer 6 and the second electrochromic layer 8 have an ion complementary relationship, so that linked color change can be realized; under the action of potential, the first electrochromic layer 6 obtains ions to reduce light transmittance, and the second electrochromic layer 8 loses ions to reduce light transmittance, so that the light transmittance change range of the electrochromic device is enlarged.
As shown in fig. 3, a laser edge deletion or laser scribing process is adopted to lead out strip-shaped bottom electrode connecting strips (13, 14, 15) and strip-shaped top electrode connecting strips (10, 11, 12) at the vacant positions 16 of the bottom electrode connecting strips reserved in the first conducting layer 5 and the outer sides of the top ends of the second conducting layers 9.
The first conductive layer 5 and the second conductive layer 9 are conventional conductive layers, and the materials include 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 to 650 nm.
The first electrochromic layer 6 is a metal oxynitride deposited film of polycrystalline structure, the film thickness may be 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) One or more of (a).
Ion conducting layer7 is selected from lithium silicon oxynitride (LiSi)zOxNy) Lithium tantalum oxynitride (LiTa)zOxNy) Lithium niobium oxynitride (LiNb)zOxNy) Lithium cobalt oxynitride (LiCo)zOxNy) Lithium aluminum oxynitride (LiAl)zOxNy) Lithium phosphorus oxynitride (LiP)zOxNy) Lithium boron oxynitride (LiB)zOxNy) One or more of (a) or (b),

In the material, the parameters of x, y and z are changed correspondingly according to the content of nitrogen.
As shown in fig. 4, the triangular electrochromic device 18 has 6 electrode strips, which are divided into 3 top-connected electrode strips and 3 bottom-connected electrode strips; the top electrode connecting strip and the bottom electrode connecting strip are distributed in an off-line mode: the electrode strips are not contacted with each other and are arranged at intervals; and top electrode connecting strips are arranged on two sides of each bottom electrode connecting strip, bottom electrode connecting strips are arranged on two sides of each top electrode connecting strip, and the top electrode connecting strips are not connected with the bottom electrode connecting strips.
One top electrode connecting strip and one bottom electrode connecting strip of the triangular electrochromic device 18 form a group of electrode drives, and three top electrode connecting strips and three bottom electrode connecting strips are combined to form three groups of electrode drives; three-group electrode time-sharing driving mode: three groups of electrode strips apply equidirectional pulse voltage in turn for equal time. The same direction pulse voltage is applied to only one group of electrode drive at a time, for example: firstly, a group of electrodes are driven and added with 10 seconds of pulse voltage, and then the electrodes are disconnected; when the circuit is switched off, a pulse voltage of 10 seconds is applied to the other group of electrodes for driving, and then the circuit is switched off; and (3) driving a third group of electrodes to add 10 seconds of pulse voltage while disconnecting, repeating the steps, driving three groups of electrodes to add equidirectional pulse voltage in turn, and changing the color of the electrochromic device 16 from three sides because the top electrode strips and the bottom electrode strips of different groups are respectively arranged at the edge position of the side length of the triangular electrochromic device 18, and then uniformly and rapidly changing the color towards the middle until the whole piece of electrochromic glass is uniformly changed in color.
In the embodiment, forward voltage is applied between the triangular electrochromic glass electrodes to drive the electrochromic glass to change color, and the color of the transparent triangular electrochromic glass gradually becomes dark until the transparent triangular electrochromic glass becomes non-transparent glass; the electrochromic glass is driven to fade by applying a reverse voltage, and the color of the electrochromic glass gradually becomes lighter until the electrochromic glass becomes transparent.
Because the electrode is in a regular triangle shape, 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 towards two sides and is gradually close to the opposite electrode strips; after voltage is applied, the potential in the electrochromic device also shows that the effective distance spanned is shortened while the potential extends from the top of the bend to two sides, so that the distribution of effective driving voltage on the electrochromic glass is improved, and the distribution is more uniform. In addition, the distribution distance of the effective driving voltage is reduced, and the voltage drop of the driving voltage on the conducting layer is greatly reduced, so that even if a lower driving voltage is used, enough effective driving voltage can be maintained at the middle part of the electrochromic glass to effectively drive, the material near the electrode strips is prevented from being in a state of higher driving voltage for a long time, the material is prevented from aging too fast, and the service life of the electrochromic glass is prolonged.
Example two, a 5 cm side equilateral triangular glass substrate 19, is illustrated in FIG. 5:
