Description
Technical Field
The application relates to the field of glass, in particular to automobile and color-changing glass.
Background
The automobile glass is a key part of an automobile, a driver can observe the road condition through the glass, and passengers in the automobile can observe the scenery outside the automobile through the glass. At present, the automobile glass comprises a three-layer structure, two layers of toughened glass and a TPV (Thermoplastic Vulcanizate) layer clamped between the toughened glass, the whole automobile glass is transparent, in order to meet other requirements such as heat insulation and sun protection, an automobile owner needs to paste a film on the automobile glass or use a sun shade, and the like, the automobile glass is very troublesome, and after the film is pasted, the color of the automobile glass is the color of the film, and the adjustment cannot be carried out.
Therefore, how to solve the above technical problems should be a great concern to those skilled in the art.
Disclosure of Invention
The application aims at providing an automobile and color-changing glass, so that the color-changing glass can realize reciprocating adjustment among different colors.
In order to solve the above technical problem, the present application provides a color-changing glass, including the relative glass substrate that sets up, set up transparent colloid layer between the glass substrate still includes:
the thin film layer is arranged between the transparent colloid layer and the glass substrate and comprises a color-changing layer and a semi-transparent perovskite solar cell;
wherein the perovskite solar cell is used for absorbing light energy and converting the light energy into electric energy; the color changing layer realizes reciprocating adjustment among different colors under the condition of voltage generated by the perovskite solar cell or heat energy converted from electric energy.
Optionally, the perovskite solar cell includes an electrode, a hole transport layer, a perovskite light absorption layer, an electron transport layer and a glass substrate, which are stacked in sequence.
Optionally, the color-changing layer includes an electrolyte layer, is located respectively the color-changing unit layer and the ion storage layer of the electrolyte layer both sides, is located respectively the color-changing unit layer is kept away from electrolyte layer one side and the ion storage layer is kept away from the transparent conducting layer of electrolyte layer one side, is located the transparent conducting layer is kept away from the substrate of electrolyte layer one side.
Optionally, the color change layer is made of PEG6 modified by ethylene glycol.
Optionally, the color-changing layer is made of any one of vanadium oxide, polymer gel particles, liquid crystal and ionic liquid.
Optionally, the electrode is MoO 3 /Ag/WO 3 And an electrode.
Optionally, the electrode is made of any one of metal, metal oxide, conductive polymer, carbon nanotube, and graphene.
Optionally, the glass substrate is ultra-white embossed tempered glass.
Optionally, the method further includes:
and the anti-reflection film is arranged on the surface of the ultra-white embossed toughened glass.
The application also provides an automobile, which comprises any one of the color-changing glass.
The application provides a glass discolours, including the relative glass substrate who sets up, set up transparent colloid layer between the glass substrate still includes: the thin film layer is arranged between the transparent colloid layer and the glass substrate and comprises a color-changing layer and a semi-transparent perovskite solar cell; wherein the perovskite solar cell is used for absorbing light energy and converting the light energy into electric energy; the color changing layer realizes reciprocating adjustment among different colors under the voltage generated by the perovskite solar cell or the heat energy converted from electric energy.
It is thus clear that be equipped with discoloration layer and perovskite solar cell in the glass that discolours in this application, perovskite solar cell is translucent state, can satisfy the requirement of glass that discolours in the aspect of the transparency, perovskite solar cell converts light energy into electric energy, and the electric energy can convert heat energy into, and discoloration layer can take place the color change under the condition of heating, or discoloration layer takes place the color change under the voltage that perovskite battery produced. Therefore, the color change can be realized to the glass that discolours in this application self, need not the pad pasting or adjust with the help of other parts, and is very convenient to, the glass that discolours of this application can carry out reciprocating motion between different colours, can satisfy the customer demand to different colours under different scenes.
