Description

Improved electronically controlled all solid state smart dimming product and its glass window

The present invention relates to the field of energy-saving technologies, and in particular relates to an improved electronically controlled all-solid smart dimming product and a preparation method thereof.

A conventional solid state electrochromic system existing in the field of electrochromic technology, consisting of a so-called "six-layer" basic model structure including a transparent substrate: a transparent substrate; a lower transparent electrode layer; a lower electrochromic layer; an ion conducting layer An electrochromic layer; and an upper transparent electrode layer.

The electrochromic system in the above model comprises two layers of reversibly oxidized or reduced materials, one of which is generally transparent, the other is generally transparent, and the transparent conductive layer is connected to an external power source, applied to Appropriate normal-phase DC voltage between the upper and lower transparent conductive electrodes, the ions of the ion storage layer are extracted, pass through the ion conductor, enter the electrochromic layer, and realize the power-free memory. When the reverse voltage is applied, the electrochromic layer is added. The ions are extracted and then enter the storage layer, and the glass returns to a transparent state. By controlling the transmittance and color of the product, the external heat radiation and internal heat diffusion are selectively absorbed or reflected. In some fields of application, a combination of two substrates can be used, each of which can maintain a partial electrochromic function, and the entire dimming system is a combination of two substrates.

Among the electrochromic basic materials, the cathode color changing material amorphous tungsten oxide is most practical, and the counter electrode generally adopts another electrochromic material complementary to the electrochromic layer, that is, if the color changing layer is a cathodic electrochromic material, An anode electrochromic material for electrodes. Under the action of the applied voltage, the cathode and the anode will be colored and discolored at the same time, so that the colored state is darker and the faded state has higher transmittance. A typical combination of such complementary discoloration is WO-NiO, WO is colored in a reduced state, and NiO is colored in an oxidized state, thereby allowing the discoloration to be deepened. Similarly, when WO is in an oxidized state, NiO is in a reduced state, thereby producing a glass having a high transmittance. In addition, solid ion conductors have also received great attention. LiF, LiA ₁ F ₄ , LiN, LiA ₁ C ₁ plasma conductor films have good overall performance.

In order to solve the problem of high production cost of the original all-solid smart dimming product, single color in the case of full light transmission and discoloration, poor visual effect, small size of the finished product, low light transmittance at full penetration, and high temperature preparation of the conductive film. The present invention enhances the visible light transmittance by optimizing the film material, the film layer structure, the process method, and particularly the dielectric composite strengthening layer and the dielectric composite protective layer, and also increases the color selection range in full penetration and discoloration. .

The technical solution of the present invention is as follows: one of the purposes of the present invention is to provide an improved electronically controlled all-solid smart dimming product, comprising a transparent substrate, and at least one side of the transparent substrate is sequentially arranged from bottom to top: a dielectric composite strengthening layer, a lower transparent electrode layer, a lower electrochromic layer, an ion conducting layer, an upper electrochromic layer, an upper transparent electrode layer and a dielectric composite protective layer.
