Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic glass, in particular to a light-conversion transparent conductive glass, a preparation method and application thereof. BACKGROUND

[0002] The conventional transparent conductive glass (such as ITO glass) generally only has the functions of electric conduction and light transmission, and cannot adjust or convert the wavelength of incident light, which results in a low light utilization rate of photovoltaic components for ultraviolet light or infrared light. The ultraviolet light (wavelength < 380 nm) is easy to penetrate and causes glass aging, and a high infrared transmittance (wavelength > 780 nm) increases the building heat load. Therefore, it is necessary to use light conversion materials in the conductive glass, but the light conversion materials (such as fluorescent powder and quantum dots) in the prior art generally exist in the form of an independent coating on the conductive glass, which easily causes interface defects or a decrease in the electric conductivity when combined with the conductive layer, and the following problems exist: (1) poor weather resistance: easy to degrade under high temperature or long-term ultraviolet irradiation; (2) weak combination with glass: the coating is easy to fall off or affect the light transmittance; (3) complex process: difficult to integrate with the conductive layer; and (4) poor compatibility: when the light conversion material (such as quantum dots) directly contacts the conductive layer, the interface defects cause an increase in the carrier recombination rate, and a decrease in the efficiency of the photovoltaic device. SUMMARY

[0003] The present application provides a light-conversion transparent conductive glass and a preparation method thereof, which solve the above problems.

[0004] To achieve the above-mentioned purpose, the present application is realized by the following technical scheme:

[0005] The present application provides a light-conversion transparent conductive glass, characterized in that the glass comprises a glass substrate, a light spectrum conversion material and a transparent conductive layer.

[0006] The light spectrum conversion material is used to convert the wavelength of ultraviolet light, and is combined with the glass substrate by means of internal doping and / or external coating. The light spectrum conversion material is externally coated on one surface of the glass substrate to form a light conversion layer, and the transparent conductive layer is stacked on the light conversion layer or directly stacked on one surface of the glass substrate.

[0007] The light spectrum conversion material has a core-shell structure, which comprises a down-conversion material as an inner core, and a first protective layer and a second protective layer successively coated on the outer side of the down-conversion material. The first protective layer is formed by a light stabilizer, and the second protective layer is formed by an organic and / or inorganic material.

[0008] Specifically, the spectrum conversion material of the present invention can convert ultraviolet light into visible light, addressing the aging problem of glass caused by ultraviolet light. Furthermore, the converted ultraviolet light can be used by photovoltaic modules, improving light utilization and boosting the power generation of photovoltaic modules.

[0009] Furthermore, a light-converting transparent conductive glass also includes an up-conversion material for converting the wavelength of infrared light. After the up-conversion material is mixed with the spectrum conversion material, it is combined with the glass substrate by internal doping and / or external coating.

[0010] Specifically, combining spectral conversion materials with upconversion materials can convert ultraviolet and infrared light into visible light, addressing both the aging issues associated with ultraviolet light and the increased heat load associated with infrared light. Therefore, when this conductive glass is used to create photovoltaic modules, these modules, when used as curtain walls in buildings, will not increase the building's heat load and will be more resistant to aging.

[0011] Specifically, the upconversion material can be NaYF4:Yb 3+ ,Er 3 (sodium yttrium fluoride doped with ytterbium and erbium) or NaYF4:Yb 3+ ,Tm 3+ (sodium yttrium fluoride doped with ytterbium and thulium); NaYF4:Yb 3+ ,Er 3 Can convert infrared light into green light, NaYF4:Yb 3+ ,Tm 3+ Can convert infrared into blue light.

[0014] Furthermore, a light-converting transparent conductive glass: the rare earth doping amount in the nanomaterial is 0.1-10.0wt%, and the rare earth element is selected from Eu 3+ 、Ce 3+ 、Yb 3+ 、Er 3+ One or more of the following: the quantum dot material is CdSe or CsPbBr3.

[0015] Further, a light-conversion transparent conductive glass: the light stabilizer is selected from light stabilizer 765 or light stabilizer 770.

[0016] The present application also provides a preparation method of the light-conversion transparent conductive glass, characterized in that the method is suitable for combining the glass substrate with the spectrum conversion material by internal doping, and comprises the following steps:

[0017] S1, taking the raw materials required for preparing the glass substrate, and then mixing the spectrum conversion material with the raw materials to form a glass liquid by melting;

[0018] S2, drawing the glass liquid to form the glass substrate internally doped with the spectrum conversion material;

[0019] S3, selecting to coat the spectrum conversion material on or not on one surface of the glass substrate obtained in step S2 to form a light conversion layer, and selecting to deposit a transparent conductive layer on the light conversion layer or on the other surface of the glass substrate to obtain the light-conversion transparent conductive glass.

[0020] Further, a preparation method of the light-conversion transparent conductive glass: the doping amount of the spectrum conversion material is 3.0-5.0% of the total weight of the raw materials.

[0021] The present application also provides another preparation method of the light-conversion transparent conductive glass, characterized in that the method is suitable for combining the glass substrate with the spectrum conversion material by external coating, and comprises the following steps:

[0022] S1, providing a glass substrate with two opposite surfaces;

[0023] S2, coating the spectrum conversion material on one surface of the glass substrate to form a light conversion layer;

[0024] S3, depositing a transparent conductive layer on the light conversion layer or on the other surface of the glass substrate to obtain the light-conversion transparent conductive glass.

[0025] The present application also provides the use of the light-conversion transparent conductive glass in laminating to prepare a perovskite photovoltaic module.

[0026] The present application has the following beneficial effects:

[0027] (1) The light-conversion transparent conductive glass provided by the present application directly incorporates the spectrum conversion material into the glass substrate, combines the conductive function of the conductive layer, realizes the effect of the conductive glass having both light conversion and conductivity, and avoids the problem of poor combination of the spectrum conversion material with the glass substrate or the conductive layer.

[0028] (2) The light conversion transparent conductive glass provided by the application can realize light conversion and conductive functions in a single glass substrate, and the glass integrates the light spectrum conversion function and transparent conductive performance, and realizes the synergistic effect of light and electricity.

[0029] (3) The application can solve the interface matching problem of the existing light conversion material and the conductive layer by using special spectrum conversion materials. At the same time, the spectrum conversion material and the up-conversion material can convert ultraviolet and infrared light into visible light, so that the ultraviolet and infrared light can also be used for photovoltaic power generation, which can improve the light utilization rate and is beneficial to the improvement of the power generation capacity of the photovoltaic assembly. At the same time, since the ultraviolet light is converted into visible light, the problem of degradation of the perovskite photovoltaic assembly caused by ultraviolet light is reduced; since the infrared light is converted into visible light, the problem of increased heat load caused by infrared light is solved.
