[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The purpose of the present invention is to provide an electric car perovskite solar canopy glass that automatically adjusts transparency based on light intensity, which includes, from top to bottom: an outer protective glass for providing physical protection and having good light transmittance; a perovskite thin film power generation layer for absorbing light energy and converting the light energy into electrical energy; a first transparent conductive layer, used as an electrode to allow current to pass without blocking light; an electrolyte layer for ion transmission.

The present invention provides a solution to the problems existing in the solar canopy glass of existing electric vehicles.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] join Figure 1 The embodiment of the present invention discloses a perovskite solar skylight glass for electric vehicles that automatically adjusts transparency based on light intensity, which includes, from top to bottom:

[0034] Outer protective glass, used to provide physical protection and has good light transmission performance;

[0035] The perovskite thin film power generation layer is used to absorb light energy and convert it into electrical energy;

[0036] A first transparent conductive layer, serving as an electrode, allows current to pass through without blocking light;

[0037] Electrolyte layer, used for ion transport.

[0038] An electrochromic material layer for changing transparency according to voltage and adjusting light transmittance;

[0039] a second transparent conductive layer, contacting one side of the electrochromic material layer to form a complete circuit;

[0040] Intermediate insulation and encapsulation layers to provide electrical isolation;

[0041] Basic protective inner layer for internal protection.

[0042] In a specific embodiment, a photosensitive sensor is embedded in the intermediate insulating and encapsulating layer to monitor external light conditions.

[0043] Specifically, the sensor can be fixed to the basic protective inner layer through the sandwich technology. The sensor is protected by the intermediate insulation and packaging layer and is not easily susceptible to external physical damage. The layer structure naturally provides good waterproof performance. At the same time, the sensor is not exposed around or on the surface of the glass, which does not affect the appearance. At the same time, it avoids the complexity and maintenance difficulties caused by being completely embedded in the glass.

[0044] In a specific embodiment, the electrochromic material layer is connected to a photosensitive sensor and an intelligent control unit of an electric vehicle, and the intelligent control unit is used to adjust the transparency of the electrochromic material.

[0045] Specifically, the internal program of the intelligent control unit is prior art.

[0046] In a specific embodiment, an ultraviolet absorbing layer is further disposed between the electrolyte layer and the electrochromic material layer.

[0047] Specifically, the main function of the ultraviolet absorption layer is to reduce the damage of ultraviolet rays to people and objects in the car. Considering that ultraviolet rays mainly come from external light, the ultraviolet absorption layer should be set at the outermost layer of the skylight glass or close to the outermost layer so that it can first contact and absorb ultraviolet rays.

[0048] In a given layer structure, the outer protective glass is the outermost layer, but because it is mainly used to protect the internal structure and provide basic light transmittance, most of the existing ultraviolet absorbing layers are set close to the inner side of the outer protective glass. The ultraviolet absorbing layer close to the outer protective glass may partially block visible light, reduce the overall light transmittance, and affect the brightness of the light inside the car. In addition, the ultraviolet absorbing layer will generate heat after absorbing ultraviolet rays. This heat may accumulate on the surface of the glass, causing local temperature rise, affecting the performance and life of the perovskite thin film power generation layer. The ultraviolet absorbing layer is exposed to the external environment for a long time and is easily affected by environmental factors such as wind, sand, and rain, which causes material aging and reduces its absorption effect. In the present application, the ultraviolet absorbing layer is set between the electrolyte layer and the electrochromic material layer, so that it is close to the outer layer and can ensure light transmittance, which has the following beneficial effects:

[0049] Placing the UV absorption layer inside can reduce its absorption of visible light, improve the overall light transmittance, and ensure sufficient light inside the car;

[0050] The internal UV absorption layer will not directly affect the optical properties of the outer protective glass, maintaining the clarity and transparency of the glass;

[0051] The heat absorbed by the UV absorption layer can be better dispersed into the electrolyte layer and the electrochromic material layer, reducing the risk of local temperature rise and protecting the performance and life of the perovskite thin film power generation layer;

[0052] The internal UV absorption layer can better maintain temperature stability and avoid performance degradation caused by temperature fluctuations;

[0053] Placing the UV absorption layer inside can prevent it from being directly exposed to the external environment, reduce the erosion of environmental factors such as wind, sand, rain, etc. on the material, and extend its service life;

[0054] The internal UV absorption layer can better maintain chemical stability and reduce material aging and degradation;

[0055] The ultraviolet absorption layer can effectively block the direct irradiation of ultraviolet rays on the electrochromic material, reduce the degradation of material performance caused by ultraviolet rays, and improve the cycle stability and response speed of the electrochromic material;

[0056] The internally set UV absorption layer can work better with other functional layers to optimize the performance of the entire skylight glass.

[0057] In a specific embodiment, an ion storage layer is disposed between the second transparent conductive layer and the intermediate insulating and encapsulating layer.

[0058] Specifically, the existing ion storage layer is adjacent to the electrochromic material layer, which may partially block the light and reduce the overall transparency. However, the present application sets the ion storage layer between the second transparent conductive layer and the intermediate insulating and encapsulating layer to form an independent ion storage area. Setting the ion storage layer between the second transparent conductive layer and the intermediate insulating and encapsulating layer can reduce its blocking of light and improve the overall transparency. At the same time, the setting method of the present invention will not directly affect the optical properties of the electrochromic material layer, and maintain the clarity and transparency of the glass. Furthermore, setting the ion storage layer between the second transparent conductive layer and the intermediate insulating and encapsulating layer can reduce the overall thickness of the electrochromic material layer, which is beneficial to the lightweight design of the device. This setting method of the present invention can better integrate the various functional layers and improve the integration and compactness of the overall device.

[0059] In a specific embodiment, a heat insulation layer is further provided between the ion storage layer and the intermediate insulation and packaging layer.

[0060] Specifically, the main function of the heat insulation layer is to reduce the transfer of heat radiation and further reduce the temperature inside the vehicle. Since heat radiation can come from direct irradiation of external light or from conduction and convection of external hot air, the position of the heat insulation layer needs to take these factors into consideration. The present invention arranges the heat insulation layer between the second transparent conductive layer and the intermediate insulation and packaging layer, which can ensure that the heat insulation layer effectively reduces the transfer of heat radiation while not affecting the function of the electrochromic layer.

[0061] In a specific embodiment, the perovskite thin film power generation layer specifically includes, from top to bottom, an electron transport layer, a perovskite thin film, a hole transport layer, and a transparent conductive substrate.

[0062] Specifically, the perovskite film is the core of the power generation layer, which is formed by depositing perovskite solar cell materials (such as CH3, NH3, PbI3 or their modified materials) on a transparent conductive substrate through a specific process. The thickness, surface morphology and crystal structure of the perovskite film have a crucial influence on the photoelectric conversion efficiency. By precisely controlling the deposition conditions, such as temperature, humidity and atmosphere, high-quality perovskite films can be obtained, thereby improving the photoelectric conversion efficiency of the battery.

[0063] Specifically, the transparent conductive substrate is the carrier for the deposition of the perovskite film, which is usually made of glass coated with ITO (indium tin oxide) or FTO (fluorine-doped tin oxide). These materials have good light transmittance and conductivity, and can effectively transfer light energy to the perovskite film and conduct the generated electrical energy. The choice of transparent conductive substrate has an important impact on the performance and stability of the battery.

[0064] Specifically, the electron transport layer is located below the perovskite film, and its main function is to collect the electrons generated in the perovskite film and efficiently transfer them to the electrode layer. In order to obtain efficient electron transfer, the electron transport layer needs to form a good interface contact with the perovskite film and have a high electron mobility, thereby improving the photoelectric conversion efficiency of the battery.

[0065] Specifically, the hole transport layer is located above the perovskite film, and its main function is to collect holes generated in the perovskite film and transfer them to the electrode layer. Similar to the electron transport layer, the hole transport layer also needs to form a good interface contact with the perovskite film and have a high hole mobility. Specifically, the embodiments of the present invention can optimize its interface contact with the perovskite film, further improving the performance of the battery.

[0066] Specifically, the electrode layer is the outermost layer of the perovskite solar cell. Its main function is to collect electrons and holes and conduct them out of the cell to form current. The electrode layer needs to have good conductivity and stability to ensure that the cell can operate stably for a long time.

[0067] Specifically, the design of the perovskite thin film power generation layer of the present invention is also reflected in the overall optimization of its structure with other layers. By accurately controlling the thickness of each layer, material selection, interface contact and other parameters, the performance and stability of the battery can be further improved. At the same time, the perovskite thin film power generation layer also has the advantages of low cost, high efficiency, easy preparation and large-scale production, which make perovskite solar cells have broad application prospects in the field of renewable energy.

[0068] In a specific embodiment, the electrochromic material layer is a smart film of electrochromic material of WO3, NiO or Prussian blue, with a thickness of 100-200nm. WO3, NiO or Prussian blue within this thickness range can provide good transparency, is suitable for adjusting light transmittance, can speed up the response time of color change, improve the reaction speed of the system, has good cycle stability, and can be used repeatedly without significant degradation.

[0069] The specific method for preparing the WO3 electrochromic material layer is as follows:

[0070] Cleaning the substrate: Use an ultrasonic cleaner and deionized water to thoroughly clean the first transparent conductive layer.

[0071] Preparation of WO3 solution: Dissolve the WO3 precursor in a suitable solvent to form a uniform solution.

[0072] Coating WO3: Use spin coating or spray coating to uniformly coat the WO3 solution on the first transparent conductive layer, with the thickness controlled at 100-200 nm.

[0073] Annealing treatment: Place the coated glass substrate into a high temperature furnace and anneal it at an appropriate temperature to form a high-quality WO3 electrochromic material layer.

[0074] The specific method for preparing the NiO electrochromic material layer is as follows:

[0075] Cleaning the substrate: Use an ultrasonic cleaner and deionized water to thoroughly clean the first transparent conductive layer.

[0076] Preparation of NiO solution: Dissolve the NiO precursor in a suitable solvent to form a homogeneous solution.

[0077] Coating NiO: Use spin coating or spray coating to uniformly coat the NiO solution on the first transparent conductive layer, with the thickness controlled at 100-200 nm.

[0078] Annealing treatment: The coated glass substrate is placed in a high temperature furnace and annealed at an appropriate temperature to form a high-quality NiO electrochromic material layer.

[0079] The specific method for preparing the Prussian blue electrochromic material layer is as follows:

[0080] Cleaning the substrate: Use an ultrasonic cleaner and deionized water to thoroughly clean the first transparent conductive layer.

[0081] Prepare Prussian blue solution: Dissolve the Prussian blue precursor in an appropriate solvent to form a homogeneous solution.

[0082] Coating Prussian blue: Use a spin coating method or a spray coating method to uniformly coat the Prussian blue solution on the first transparent conductive layer, and the thickness is controlled to be 100-200 nm.

[0083] Annealing treatment: The coated glass substrate is placed in a high temperature furnace and annealed at an appropriate temperature to form a high-quality Prussian blue electrochromic material layer.

[0084] In a specific embodiment, the material of the first transparent conductive layer is AZO aluminum-doped zinc oxide or ITO indium tin oxide, with a thickness of 50-70 nm. This thickness can improve transparency and reduce absorption and scattering of visible light. Within this thickness range, AZO and ITO can both provide good conductivity and meet the requirements of the electrochromic material layer. The film layer within this thickness range has sufficient mechanical strength to withstand stress during processing and use.

[0085] In a specific embodiment, the material of the second transparent conductive layer is AZO aluminum-doped zinc oxide or ITO indium tin oxide, with a thickness of 50-70nm. Similar to the first transparent conductive layer, the film layer of this thickness can improve transparency. Within this thickness range, both AZO and ITO can provide good conductivity to ensure that the voltage regulation function of the electrochromic material layer works normally. The film layer within this thickness range has sufficient mechanical strength to withstand stress during processing and use.

[0086] In a specific embodiment, the stronger the light intensity, the greater the power generation of the perovskite thin film power generation layer. The electrochromic material layer located below the perovskite thin film power generation layer is connected in parallel / series in the top perovskite battery power generation collection circuit. The current and voltage in the electrochromic material layer circuit loop increase, which reduces the transparency of the electrochromic material layer and increases the bottom reflection, thereby reducing the transmittance of the incident light of the perovskite thin film power generation layer. The power generation of the perovskite thin film power generation layer battery is enhanced, making the perovskite thin film power generation layer generate more power, and reducing the light transmittance of the skylight glass, thereby reducing the temperature inside the car.

[0087] When the light intensity decreases, the power generation of the perovskite thin film power generation layer decreases, and the current or voltage in the electrochromic material layer circuit loop decreases, which increases the transparency of the electrochromic material layer. While maintaining the power generation of the perovskite thin film power generation layer battery, it increases the transmittance of the incident light, ensuring sufficient light and stable temperature in the car.
