Description

Technical Field

[0001] This invention belongs to the field of photovoltaic equipment technology, and in particular to a cadmium telluride photovoltaic module, a photovoltaic roof, and a power-generating glass curtain wall. Background Technology

[0002] Cadmium telluride photovoltaic (CTD) modules, also known as power-generating glass or photovoltaic glass, are solar cells with a cadmium telluride thin film. They convert light energy into electrical energy. Unlike ordinary solar cells, CTD modules have excellent light transmittance, making them a new type of building material in the construction industry. Colored CTD photovoltaic modules consist of a backsheet glass, a CTD substrate, and a surface glass. The CTD substrate is mounted on the backsheet glass. In practical use, the substrate lacks external protection and is easily affected by external factors, especially damaging internal components and structures.

[0003] A search revealed a Chinese patent document (authorization announcement number CN222071958U) concerning a cadmium telluride photovoltaic module, a photovoltaic roof, and a power-generating glass curtain wall. The cadmium telluride photovoltaic module includes a front glass panel, a cadmium telluride structural layer, and a back glass panel. One side of the front glass panel has a frosted surface, while the other side has an embossed surface. The cadmium telluride structural layer is located on one side of the front glass panel and faces it. The back glass panel is located on the side of the cadmium telluride structural layer away from the front glass panel. This invention addresses the problem that colored cadmium telluride photovoltaic modules have strong light reflection capabilities, easily causing light pollution and affecting power generation efficiency. While the aforementioned patent offers good performance, it lacks external protection, making it susceptible to external influences, especially damaging internal instruments and structures. Summary of the Invention

[0004] The purpose of this invention is to provide a cadmium telluride photovoltaic module, a photovoltaic roof, and a power-generating glass curtain wall to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cadmium telluride photovoltaic module, comprising: Cadmium telluride structure; Two glass plates are respectively placed on both sides of the cadmium telluride structure to protect the cadmium telluride structure. An adhesive film connects the glass plates to the cadmium telluride structure. A protective frame is attached to the outer periphery of two glass plates, and an assembly plate is fixedly connected to the back of the protective frame; A counterweight plate is positioned below the assembly plate. A first protective shell is installed at the top of the counterweight plate. A vertical servo motor for tracking light is installed on the inner wall of the first protective shell. The output shaft of the vertical servo motor passes through the first protective shell and is connected to a vertical rotating rod. A second protective shell is installed at the top of the vertical rotating rod. A horizontal servo motor for tracking light is installed on the inner wall of the second protective shell. The output shaft of the horizontal servo motor is connected to a horizontal rotating rod. A T-shaped connecting plate is fixedly connected to the side of the horizontal rotating rod. The connecting plate is detachably connected to the assembly plate.

[0006] In a preferred embodiment, both the first and second protective shells are rotatably connected to an easy-to-operate maintenance door on their sides, and both the first and second protective shells are connected and fixed to the maintenance door by a latch.

[0007] As a preferred embodiment, both the first protective shell and the second protective shell have multiple heat dissipation channels for natural ventilation on their outer periphery.

[0008] As a preferred embodiment, a vertical electric push rod is installed at the top of the counterweight plate, multiple limiting tubes are fixedly connected to the bottom of the protective frame, and multiple round holes are opened at the top of the counterweight plate, with fixing bolts for fixing inside the round holes.

[0009] In a preferred embodiment, the top end of the moving part of the vertical electric push rod is fixedly connected to a mounting plate, and the top end of the mounting plate is connected to a plurality of insert rods for insertion into the limiting tube.

[0010] As a preferred embodiment, a colored light-transmitting film is provided on the side of the cadmium telluride structure away from the assembly plate, and a limiting frame is detachably connected to the inner wall of the protective frame, with the limiting frame located below the cadmium telluride structure.

[0011] As a preferred embodiment, the protective frame, assembly plate, first protective shell, second protective shell and counterweight plate are all made of alloy materials and their outer surfaces are coated with matte paint.

[0012] A photovoltaic roof includes a roof structure for mounting cadmium telluride photovoltaic modules.

[0013] A power-generating glass curtain wall includes a mounting frame for installing cadmium telluride photovoltaic modules.

[0014] Compared with the prior art, the technical effects and advantages of the present invention are as follows: The cadmium telluride photovoltaic module, photovoltaic roof, and power-generating glass curtain wall benefit from the design of the glass panels and protective frame. Two glass panels are respectively attached to both sides of the cadmium telluride structure, directly isolating external physical interference such as dust, rain, and scratches, while avoiding oxidation or aging of the structure due to direct exposure. The protective frame connects the outer perimeter of the two glass panels to form a closed "sandwich" structure, which not only enhances the bonding stability between the glass panels and the cadmium telluride structure, but also prevents moisture, insects, etc. from entering the module. The detachable limiting frame on the inner wall of the protective frame provides additional support from below the cadmium telluride structure, preventing structural displacement caused by gravity or vibration during long-term use of the module, and further ensuring the integrity of the power generation layer. This cadmium telluride photovoltaic module, photovoltaic roof, and power-generating glass curtain wall achieves precise adjustment of the module's orientation through a dual-dimensional drive structure of "vertical + horizontal," solving the efficiency shortcoming of traditional fixed photovoltaic modules that "cannot track the sun's trajectory." The vertical servo motor drives the entire module to rotate around the vertical axis through a vertical rotating rod, achieving "left-right" orientation adjustment, such as tracking the sun's rise and set. The horizontal servo motor drives the module to rotate around the horizontal axis through a horizontal rotating rod, achieving "up-down" tilt adjustment, such as adjusting the tilt angle according to seasonal changes in the sun's altitude angle. The connection between the T-shaped connecting plate and the assembly plate, and the second protective shell's enclosure of the horizontal motor, ensure that the module does not shake during the adjustment process, guaranteeing the accuracy of angle adjustment and structural safety. This cadmium telluride photovoltaic module, photovoltaic roof, and power-generating glass curtain wall not only has excellent protective functions and extends the life of the module, but also offers flexible adjustment and improves photovoltaic conversion efficiency.

[0017] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0018] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0019] Please see Figures 1 to 6 A cadmium telluride photovoltaic module, comprising: The cadmium telluride structure 1 is the core functional layer for realizing photoelectric conversion. Its essence is a "pn junction" structure (the core structure of semiconductor devices, responsible for separating photogenerated charge carriers) mainly composed of cadmium telluride semiconductor materials. Together with other auxiliary functional layers, it completes the process of "absorbing sunlight → generating photogenerated charge → extracting electrical energy". Two glass plates 2 are respectively set on both sides of the cadmium telluride structure 1 to protect the cadmium telluride structure 1. The two glass plates 2 are respectively attached to both sides of the cadmium telluride structure 1 to directly isolate external physical interference such as dust, rain, and scratches, while avoiding oxidation or aging of the structure due to direct exposure. There is an adhesive film connecting the glass plates 2 and the cadmium telluride structure 1. The protective frame 3 is connected to the outer periphery of the two glass plates 2. The back of the protective frame 3 is fixedly connected to the mounting plate 4. The protective frame 3 connects to the outer periphery of the two glass plates 2 to form a closed "sandwich" structure, which not only strengthens the bonding stability between the glass plate 2 and the cadmium telluride structure 1, but also prevents water vapor, insects and other substances from entering the interior of the component. A counterweight plate 5 is positioned below the assembly plate 4. A first protective shell 6 is mounted on the top of the counterweight plate 5. A vertical servo motor 7 for tracking sunlight is mounted on the inner wall of the first protective shell 6. The output shaft of the vertical servo motor 7 passes through the first protective shell 6 and is connected to a vertical rotating rod 8. A second protective shell 9 is mounted on the top of the vertical rotating rod 8. A horizontal servo motor 10 for tracking sunlight is mounted on the inner wall of the second protective shell 9. The output shaft of the horizontal servo motor 10 is connected to a horizontal rotating rod 11. A T-shaped connecting plate 12 is fixedly connected to the side of the horizontal rotating rod 11. The connecting plate 12 is detachably connected to the assembly plate 4. Adjusting the vertical servo motor 7 and the horizontal servo motor 10 can adjust the angle of the cadmium telluride structure 1, allowing the cadmium telluride structure 1 to move with the sun and improve photovoltaic conversion efficiency.

[0020] The vertical servo motor 7 and the horizontal servo motor 10 are controlled by the controller through encoding and adjusted according to time. The adjustment frequency is set at every ten minutes or every thirty minutes to achieve light tracking.

[0021] Both the first protective shell 6 and the second protective shell 9 have easily operable access doors 13 rotatably connected to their sides. The first protective shell 6 and the second protective shell 9 are fixed to the access doors 13 by latches. The doors can be opened without disassembling the entire structure, which facilitates the inspection, maintenance or replacement of the internal motors and reduces maintenance time. The outer periphery of the first protective shell 6 and the second protective shell 9 are provided with multiple heat dissipation channels for natural ventilation, which can use natural wind to remove the heat generated by the servo motor during operation, avoid damage to the motor due to high temperature overload, and reduce the probability of failure and maintenance frequency.

[0022] For fixation, a vertical electric push rod 14 is installed at the top of the counterweight plate 5, and multiple limiting tubes 15 are fixedly connected to the bottom of the protective frame 3. Multiple round holes are opened at the top of the counterweight plate 5, and fixing bolts for fixing are set in the round holes. Its own weight can offset the swaying torque of the component caused by wind and temperature difference due to sunlight. At the same time, the round holes on the counterweight plate 5, together with the fixing bolts, can anchor the overall structure to the installation foundation (such as concrete base or roof support) to prevent the component from shifting or tipping over. The top of the moving part of the vertical electric push rod 14 is fixedly connected to the mounting plate 16, and the top of the mounting plate 16 is connected to multiple insertion rods 17 for inserting into the limiting tubes 15. In windy weather, the protective frame 3 is adjusted to a specified angle, and the vertical electric push rod 14 is controlled to extend, so that the insertion rods 17 are inserted into the limiting tubes 15, further improving the stability of the protective frame 3 and the auxiliary structure.

[0023] A colored translucent film 18 is also provided on the side of the cadmium telluride structure 1 away from the assembly plate 4. The inner wall of the protective frame 3 is detachably connected to a limiting frame 19, and the limiting frame 19 is located below the cadmium telluride structure 1. The limiting frame 19 detachably connected to the inner wall of the protective frame 3 provides additional support from below the cadmium telluride structure 1 to prevent structural displacement caused by gravity or vibration during long-term use of the module, and further ensure the integrity of the power generation layer. The protective frame 3, assembly plate 4, first protective shell 6, second protective shell 9 and counterweight plate 5 are all made of alloy materials, which have the characteristics of high strength and corrosion resistance (resistance to rust caused by rain and ultraviolet rays). The outer surface is coated with matte paint. The matte paint coating on the outer surface can further enhance the resistance to ultraviolet aging and avoid the strong light reflection pollution of traditional glossy coatings. At the same time, it makes the appearance of the module simpler and more low-key, which is suitable for the aesthetic requirements of building facades (such as photovoltaic curtain walls).

[0024] This solution not only ensures the core power generation performance and structural stability of cadmium telluride photovoltaic modules, but also, through flexible adjustment, convenient operation and maintenance, aesthetic appeal, durability, and functional expansion design, is applicable to various scenarios such as rooftop photovoltaics, ground-mounted power stations, and building-integrated photovoltaics, demonstrating high practicality and market adaptability.

[0025] A photovoltaic roof includes a roof structure for mounting cadmium telluride photovoltaic modules.

[0026] A power-generating glass curtain wall includes a mounting frame for installing cadmium telluride photovoltaic modules.

[0027] The vertical servo motor 7, the horizontal servo motor 10, and the vertical electric push rod 14 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this invention is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the art. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this invention. All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art.

[0028] Working principle The cadmium telluride photovoltaic module, photovoltaic roof and power-generating glass curtain wall are installed in sequence. The vertical servo motor 7 and the horizontal servo motor 10 can adjust the angle of the cadmium telluride structure 1, so that the cadmium telluride structure 1 moves with the sun, thereby improving the photovoltaic conversion efficiency. In windy weather, the protective frame 3 is adjusted to a specified angle, and the vertical electric push rod 14 is extended so that the insertion rod 17 is inserted into the limiting tube 15, further improving the stability of the protective frame 3 and its auxiliary structures.
