[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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0031] The purpose of this utility model is to provide a perovskite solar skylight glass for electric vehicles that automatically adjusts its transparency based on light intensity. The glass comprises, from top to bottom, an outer protective glass layer for physical protection and good light transmittance; a perovskite thin-film power generation layer for absorbing light energy and converting it into electrical energy; a first transparent conductive layer, serving as an electrode, allowing current to pass without blocking light; an electrolyte layer for ion transport; an electrochromic material layer for changing transparency based on voltage and adjusting light transmittance; a second transparent conductive layer in contact with one side of the electrochromic material layer to form a complete circuit; an intermediate insulating and encapsulating layer for electrical isolation; and a base protective inner layer for internal protection. This utility model provides a solution to the problems existing in solar skylight glass for 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 implementation methods.

[0033] join Figure 1 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 have good light transmission performance;

[0035] Perovskite thin film power generation layer, used to absorb light energy and convert it into electrical energy;

[0036] a first transparent conductive layer, serving as an electrode, allowing current to pass without blocking light;

[0037] Electrolyte layer, used for ion transport.

[0038] An electrochromic material layer, which is used to change transparency according to voltage and adjust light transmittance;

[0039] a second transparent conductive layer in contact with one side of the electrochromic material layer to form a complete circuit;

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

[0041] Basic protective inner layer for internal protection.

[0042] In a specific embodiment, a light-sensitive 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 interlayer 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 on the sides or surface of the glass, which does not affect the appearance, and avoids the complexity and maintenance difficulties brought by being completely embedded in the glass.

[0044] In a specific embodiment, the electrochromic material layer is connected to a photosensor 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 provided between the electrolyte layer and the electrochromic material layer.

[0047] Specifically, the UV absorption layer's primary function is to reduce UV damage to people and objects inside the vehicle. Considering that UV rays primarily originate from external light, the UV absorption layer should be located at or near the outermost layer of the skylight glass so that it is the first to be exposed to and absorb UV 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. The present application arranges the ultraviolet absorbing layer 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 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] Setting 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, and rain 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 exposure of ultraviolet rays to 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 one 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 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 conducive 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 insulating and packaging layer.

[0060] Specifically, the main function of the thermal insulation layer is to reduce the transfer of heat radiation, further lowering the temperature inside the vehicle. Since heat radiation can originate from direct exposure to external light, as well as conduction and convection from external hot air, the placement of the thermal insulation layer requires comprehensive consideration of these factors. The present invention places the thermal insulation layer between the second transparent conductive layer and the intermediate insulating and encapsulating layer, ensuring that the thermal insulation layer effectively reduces the transfer of heat radiation while maintaining the functionality of the electrochromic layer.

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

[0062] Specifically, the perovskite film is the core of the power generation layer. It 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 impact 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 cell.

[0063] Specifically, the transparent conductive substrate, the carrier for the perovskite thin film deposition, is typically made of glass coated with ITO (indium tin oxide) or FTO (fluorine-doped tin oxide). These materials have excellent light transmittance and conductivity, effectively transmitting light energy to the perovskite thin film and conducting the generated electrical energy out. The choice of transparent conductive substrate has a significant impact on the performance and stability of the battery.

[0064] Specifically, the electron transport layer is located below the perovskite film. Its main function is to collect electrons generated in the perovskite film and efficiently transfer them to the electrode layer. To achieve 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. Its primary 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 with the perovskite film and have a high hole mobility. Specifically, embodiments of the present invention can optimize its interface contact with the perovskite film, further improving battery performance.

[0066] Specifically, the electrode layer is the outermost layer of a perovskite solar cell. Its primary function is to collect electrons and holes and conduct them out of the cell to form an electric current. The electrode layer needs to have good conductivity and stability to ensure the long-term stable operation of the cell.

[0067] Specifically, the design of the perovskite thin-film power generation layer in this utility model is also reflected in the overall optimization of its structure with other layers. By precisely controlling parameters such as the thickness, material selection, and interface contact of each layer, the performance and stability of the cell can be further improved. Furthermore, the perovskite thin-film power generation layer offers advantages such as low cost, high efficiency, ease of preparation, and large-scale production. These advantages make perovskite solar cells promising for broad application in the renewable energy sector.

[0068] In one embodiment, the electrochromic material layer is a smart film of WO3, NiO, or Prussian blue, with a thickness of 100-200 nm. WO3, NiO, or Prussian blue within this thickness range provides good transparency, is suitable for adjusting light transmittance, accelerates color change response time, improves system responsiveness, and exhibits good cycling stability, allowing for repeated use 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 an appropriate solvent to form a uniform solution.

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

[0073] Annealing treatment: Place the coated glass substrate in a high-temperature furnace and anneal 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 an appropriate 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: Place the coated glass substrate in a high-temperature furnace and anneal 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, with a thickness controlled at 100-200 nm.

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

[0084] In one specific embodiment, the first transparent conductive layer is made of AZO (aluminum-doped zinc oxide) or ITO (indium tin oxide), with a thickness of 50-70 nm. This thickness improves transparency and reduces visible light absorption and scattering. Within this thickness range, both AZO and ITO provide good conductivity, meeting the requirements of an electrochromic material layer. The film layer within this thickness range also has sufficient mechanical strength to withstand the stresses experienced during processing and use.

[0085] In one specific embodiment, the second transparent conductive layer is made of AZO (aluminum-doped zinc oxide) or ITO (indium tin oxide), with a thickness of 50-70 nm. Similar to the first transparent conductive layer, this thickness improves transparency. Within this thickness range, both AZO and ITO provide good conductivity, ensuring the proper function of the voltage regulation function of the electrochromic material layer. The film within this thickness range also provides sufficient mechanical strength to withstand the stresses experienced 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 increase in current and voltage in the electrochromic material layer circuit loop reduces the transparency of the electrochromic material layer, increases the bottom surface reflection, and reduces 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 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.
