Description

Technical Field

[0001] This utility model relates to the field of energy-saving doors and windows technology, and in particular to a photovoltaic door and window. Background Technology

[0002] With the rise of Building-Integrated Photovoltaics (BIPV), photovoltaic modules are being used in increasingly diverse applications in buildings, including facades, roofs, and windows. Photovoltaic windows, as one application of photovoltaic modules, not only fulfill basic building functions such as lighting and ventilation but also generate electricity using solar energy, improving the building's energy efficiency.

[0003] Due to the power generation requirements of photovoltaic (PV) doors and windows, the PV cables are usually concealed within the door and window frame during the design process to transmit current, thereby ensuring overall aesthetics and safety. Common PV doors and windows mainly adopt fixed or sliding structures. Sliding doors and windows generally consist of two doors, left and right, both of which can move left and right along guide rails to achieve opening and closing functions.

[0004] However, in the application scenario of BIPV sliding photovoltaic doors and windows, traditional cable transmission methods have obvious drawbacks. Since the opening and closing of sliding photovoltaic doors and windows is achieved by sliding left and right or extending and retracting, the photovoltaic cables need to be bent repeatedly and continuously extend and retract with the movement of the doors and windows, which can easily lead to cable wear and breakage, thereby affecting the long-term reliability of photovoltaic doors and windows, and may even pose safety hazards.

This ensures that during the sliding motion of the photovoltaic panel by the door / window frame, the first conductive structure maintains stable electrical contact with the positive conductive strip, and the second conductive structure maintains stable electrical contact with the negative conductive strip.

[0041] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0042] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0043] Figure 1 This is a structural schematic diagram of a photovoltaic door and window provided in an embodiment of this utility model, as shown below. Figure 1As shown, the photovoltaic door and window includes: a door and window slide rail 1 extending along a first direction X; at least one door and window frame 2 slidably connected to the door and window slide rail 1; at least one photovoltaic panel 3 installed in the door and window frame 2; the photovoltaic panel 3 is provided with a positive conductive strip 41 and a negative conductive strip 42 that are insulated from each other; both the positive conductive strip 41 and the negative conductive strip 42 extend along the first direction X; at least one first conductive structure 51 and at least one second conductive structure 52 are fixed in the door and window slide rail 1; the first end of each first conductive structure 51 is in contact with the positive conductive strip 41 on each photovoltaic panel 3, and the first end of each second conductive structure 52 is in contact with the negative conductive strip 42 on each photovoltaic panel 3.

[0044] Specifically, the window / door track 1 can be understood as a track structure that supports and guides the sliding of the window / door frame 2, and extends along the first direction X. The photovoltaic window / door may include one or more window / door frames 2. The window / door track 1 can be fixed to the top or bottom of each window / door frame 2, or it can be fixed to both the top and bottom of each window / door frame 2 simultaneously, so that each window / door frame 2 can slide smoothly along the first direction X. The arrangement of the window / door track 1, the specific number of window / door frames 2, and the first direction X can be determined according to actual needs, and this utility model does not specifically limit them. For ease of description, unless otherwise specified, reference will continue to be made. Figure 1 In this embodiment of the utility model, the technical solution of the utility model is illustrated by taking the example of a door and window sliding rail 1 fixed to the top of a door and window frame 2, a photovoltaic door and window including a door and window frame 2, and the first direction X being horizontal. The door and window frame 2 can be understood as a structure for supporting the photovoltaic panel 3, and is slidably connected to the door and window sliding rail 1 so that the door and window frame 2 can smoothly drive the photovoltaic panel 3 to slide on the door and window sliding rail 1. It is understood that the photovoltaic door and window may include one or more photovoltaic panels 3, and the photovoltaic panels 3 are installed one-to-one in the door and window frame 2, that is, the number of photovoltaic panels 3 is the same as the number of door and window frames 2. For example, the material of the door and window frame 2 can be high-strength aluminum alloy or steel, etc., to ensure that the photovoltaic panel 3 can be stably installed in the door and window frame 2, avoiding damage to the photovoltaic panel 3 during the sliding of the door and window frame 2 within the door and window sliding rail 1, thereby ensuring the stability and durability of the photovoltaic door and window.

[0045] The photovoltaic panel 3 can be specifically understood as a photovoltaic module used to convert solar energy into electrical energy. For example, the photovoltaic panel 3 can be a transparent photovoltaic panel or a semi-transparent photovoltaic panel. After receiving sunlight, the photovoltaic panel 3 can convert light energy into electrical energy. Simultaneously, the photovoltaic panel 3 is provided with mutually insulated positive conductive strips 41 and negative conductive strips 42, so that the positive conductive strip 41 can transmit the positive current generated by the photovoltaic panel 3, and the negative conductive strip 42 can transmit the negative current generated by the photovoltaic panel 3, realizing the power generation function of the photovoltaic window / door. For example, the positive conductive strip 41 and negative conductive strip 42 can be copper strips, which have good conductivity to effectively reduce power loss and improve the transmission efficiency of photovoltaic current. The positive conductive strip 41 and negative conductive strip 42 can be attached to the photovoltaic panel 3 with conductive double-sided adhesive, without the need for additional mechanical fixing devices or welding processes, thus simplifying the installation process. At the same time, the conductive double-sided adhesive ensures good contact between the positive conductive strip 41 and negative conductive strip 42 and the photovoltaic panel 3, reducing contact resistance and thereby improving current transmission efficiency.

[0046] Furthermore, the photovoltaic doors and windows also include one or more first conductive structures 51 and one or more second conductive structures 52 fixed within the door and window slide rail 1. The first end of each first conductive structure 51 is in contact with the positive conductive strip 41 on each photovoltaic panel 3, and the first end of each second conductive structure 52 fixed within the door and window slide rail 1 is in contact with the negative conductive strip 42 on each photovoltaic panel 3. That is, the door and window slide rail 1 is fixed with first conductive structures 51 that are in one-to-one contact with the positive conductive strip 41 on each photovoltaic panel 3, and second conductive structures 52 that are in one-to-one contact with the negative conductive strip 42 on each photovoltaic panel 3. Therefore, the number of first conductive structures 51 and positive conductive strips 41 fixed on the door and window slide rail 1 is the same, and the number of second conductive structures 52 and negative conductive strips 42 fixed on the door and window slide rail 1 is the same.

[0047] Continue to refer to Figure 1 When a photovoltaic door / window includes a door / window frame 2 and a photovoltaic panel 3 installed in the door / window frame 2, a first conductive structure 51 that contacts the positive conductive strip 41 on the photovoltaic panel 3 and a second conductive structure 52 that contacts the negative conductive strip 42 on the photovoltaic panel 3 are fixed on the door / window slide rail 1. For example, both the first conductive structure 51 and the second conductive structure 52 may include conductive pins. The material of the conductive pins may be a gold-plated, silver-plated, or nickel-plated copper alloy to ensure that the first conductive structure 51 maintains a stable electrical connection with the positive conductive strip 41 on the photovoltaic panel 3, and that the second conductive structure 52 maintains a stable electrical connection with the negative conductive strip 42 on the photovoltaic panel 3, effectively reducing contact resistance. The first conductive structure 51 and the second conductive structure 52 may also include cables electrically connected to the conductive pins to stably transmit the current transmitted by the conductive pins to subsequent circuits, improving the efficiency and reliability of current transmission.

[0048] Both the positive conductive strip 41 and the negative conductive strip 42 extend along the first direction X, meaning that the extending directions of the positive conductive strip 41 and the negative conductive strip 42 are consistent with the sliding direction of the door and window frame 2 within the door and window slide rail 1. This ensures that during the sliding process of the door and window frame 2 and the photovoltaic panel 3 installed inside it within the door and window slide rail 1, the first conductive structure 51 and the positive conductive strip 41, and the second conductive structure 52 and the negative conductive strip 42, can always maintain stable electrical contact. This allows the positive current generated by the photovoltaic panel 3 to be transmitted through the positive conductive strip 41 to the first conductive structure 51, and further output through the first conductive structure 51, as well as the photovoltaic... The negative current generated by plate 3 can be transmitted to the second conductive structure 52 through the negative conductive strip 42, and further output through the second conductive structure 52. Since the first conductive structure 51 and the second conductive structure 52 remain stationary, they will not bend as the photovoltaic panel 3 is moved by the window frame 2. This ensures a long service life for the first and second conductive structures 51 and 52, thereby ensuring continuous current transmission during the sliding process of the photovoltaic window, improving the stability of the photovoltaic window during sliding, and enhancing the power generation efficiency and reliability of the photovoltaic window. In an exemplary embodiment, the first conductive structure 51 and the second conductive structure 52 can be fixed at the middle position of the window slide rail 1 along the first direction X, so as to better ensure that the first conductive structure 51 and the positive conductive strip 41, and the second conductive structure 52 and the negative conductive strip 42, maintain stable electrical contact throughout the entire sliding process of the window frame 2 within the window slide rail 1.

[0049] It is also understandable that before the first conductive structure 51 and the second conductive structure 52 are fixed to the door and window slide rail 1, the first conductive structure 51 and the second conductive structure 52 can move up and down within the door and window slide rail 1 along the second direction Y intersecting the first direction X, to adapt to the height changes of the positive conductive strip 41 and the negative conductive strip 42 provided on the photovoltaic panel 3. After the first end of the first conductive structure 51 establishes good contact with the positive conductive strip 41 on the photovoltaic panel 3, and the first end of the second conductive structure 52 establishes good contact with the negative conductive strip 42 on the photovoltaic panel 3, the positions of the first conductive structure 51 and the second conductive structure 52 can be locked by means of mechanical limiting, magnetic locking, or friction clamping, to ensure a stable electrical connection between the first conductive structure 51 and the positive conductive strip 41, and between the second conductive structure 52 and the negative conductive strip 42. The ability of the first conductive structure 51 and the second conductive structure 52 to move up and down to adjust to the optimal contact position achieves improved durability and installation adaptability of the photovoltaic door and window while ensuring the stability of current transmission.

[0050] In this embodiment, a door / window track extending along a first direction is provided inside the photovoltaic door / window, along with at least one door / window frame slidably connected to the track, enabling each door / window frame to slide smoothly along the first direction. At least one photovoltaic panel is installed within the door / window frame, allowing each panel to slide along the track. The photovoltaic panel converts light energy into electrical energy. Furthermore, the photovoltaic panel is equipped with mutually insulated positive and negative conductive strips, allowing the positive and negative conductive strips to respectively transmit the positive and negative currents generated by the photovoltaic panel, thereby enabling the photovoltaic door / window to generate electricity. Furthermore, both the positive and negative conductive strips extend along a first direction. At least one first conductive structure and at least one second conductive structure are fixed within the door / window sliding track. The first end of each first conductive structure contacts the positive conductive strip on each photovoltaic panel, and the first end of each second conductive structure contacts the negative conductive strip on each photovoltaic panel. This ensures that during the sliding motion of the photovoltaic panel by the door / window frame, the first conductive structure maintains stable electrical contact with the positive conductive strip, and the second conductive structure maintains stable electrical contact with the negative conductive strip. This allows the positive current generated by the photovoltaic panel to be transmitted through the positive conductive strip to the negative conductive strip. A first conductive structure is used, and the output is further through the first conductive structure. The negative electrode current generated by the photovoltaic panel can be transmitted to the second conductive structure through the negative electrode conductive strip, and then output through the second conductive structure. Since the first and second conductive structures remain stationary, they will not bend as the photovoltaic panel moves with the door and window frame. This ensures that the first and second conductive structures of the door have a long service life, thereby ensuring the continuous transmission of current during the sliding process of the photovoltaic door and window, improving the stability of the photovoltaic door and window during the sliding process, and enhancing the power generation efficiency and reliability of the photovoltaic door and window.

[0051] Optional, Figure 2 This is a schematic diagram of another photovoltaic door / window structure provided in this embodiment of the present invention, as shown below. Figure 2 As shown, the first conductive structure 51 includes a first conductive pin 501 and a first cable 502 connected to each other; both the first conductive pin 501 and the first cable 502 are fixed inside the door and window slide rail 1, and the first end of the first conductive pin 501 is in contact with the positive conductive strip 41, and the second end of the first conductive pin 501 is electrically connected to the first cable 502; the second conductive structure 52 includes a second conductive pin 503 and a second cable 504 connected to each other; both the second conductive pin 503 and the second cable 504 are fixed inside the door and window slide rail 1, and the first end of the second conductive pin 503 is in contact with the negative conductive strip 42, and the second end of the second conductive pin 503 is electrically connected to the second cable 504; wherein, the external load 00 is electrically connected between the first cable 502 and the second cable 504.

[0052] The first conductive structure 51 includes a first conductive pin 501 and a first cable 502 connected to each other. The second conductive structure 52 includes a second conductive pin 503 and a second cable 504 connected to each other. The first end of the first conductive pin 501 is in contact with the positive conductive strip 41, and the first end of the second conductive pin 503 is in contact with the negative conductive strip 42. The materials of the first conductive pin 501 and the second conductive pin 503 can be gold-plated, silver-plated, or nickel-plated copper alloys to ensure that the first conductive pin 501 and the positive conductive strip 41 maintain a stable electrical connection, and the second conductive pin 503 and the negative conductive strip 42 maintain a stable electrical connection, effectively reducing contact resistance. The second end of the first conductive pin 501 is electrically connected to the first cable 502, and the second end of the second conductive pin 503 is electrically connected to the second cable 504, so that the first cable 502 and the second cable 504 can transmit the positive and negative currents generated by the photovoltaic panel 3 to the external load 00.

[0053] Specifically, after the photovoltaic panel 3 receives sunlight, it converts light energy into electrical energy. The positive current generated by the photovoltaic panel 3 can be transmitted through the positive conductive strip 41 to the first conductive pin 501 and the first cable 502, and further output to the external load 00 through the first cable 502. At the same time, the negative current generated by the photovoltaic panel 3 can be transmitted through the negative conductive strip 42 to the second conductive pin 503 and the second cable 504, and further output to the external load 00 through the second cable 522. The first conductive pin 501, the first cable 502, the second conductive pin 503, and the second cable 504 are all fixed in the door and window sliding rail 1 to ensure that the first conductive pin 501, the first cable 502, the second conductive pin 503, and the second cable 504 will not be pulled or damaged during the sliding of the door and window frame 2, thereby ensuring the continuous transmission of current during the sliding of the photovoltaic door and window and improving the stability of the photovoltaic door and window during the sliding process. In one exemplary embodiment, the first cable 502 and the second cable 504 can be arranged along a first direction in the door / window sliding rail 1, and led out at one end of the door / window sliding rail 1 and directly electrically connected to the external load 00, thereby reducing additional wiring structures and lowering the installation complexity of the photovoltaic door / window. In another exemplary embodiment, the first cable 502 and the second cable 504 can be connected to a junction box installed on or near one end of the door / window sliding rail 1. The junction box integrates terminal blocks or connectors to enable the first cable 502 and the second cable 504 to connect to the external load 00. The junction box can effectively protect the first cable 502 and the second cable 504 from the external environment, such as dust, moisture, mechanical impact, etc., improving the safety and service life of the photovoltaic door / window.

[0054] An external load 00 is electrically connected between the first cable 502 and the second cable 504, enabling the external load 00 to receive and utilize the electrical energy generated by the photovoltaic panel 3. For example, the external load 00 may include a DC device or other AC device connected between the first cable 502 and the second cable 504 via an inverter. The specific design can be tailored to actual needs, and this embodiment of the invention does not impose specific limitations on this design.

[0055] Optional, Figure 3 This is a structural schematic diagram of a photovoltaic panel provided in an embodiment of the present invention, as shown below. Figure 3 As shown, the photovoltaic panel 3 includes a first conductive glass 301, a second conductive glass 302, and a perovskite cell 303 located between the first conductive glass 301 and the second conductive glass 302.

[0056] Specifically, the first conductive glass 301 can be understood as the front glass of the photovoltaic panel 3, possessing high light transmittance to maximize the transmission of sunlight to the internal perovskite cell 303, thereby improving the photovoltaic conversion efficiency of the photovoltaic door / window. The surface of the first conductive glass 301 can be coated with a transparent conductive oxide, such as fluorine-doped tin oxide (FTO) or indium tin oxide (ITO), to collect the photocurrent generated by the perovskite cell 303 and transmit it to the positive conductive strip 41 and negative conductive strip 42 disposed on the first conductive glass 301. Furthermore, the first conductive glass 301 also provides a certain degree of mechanical strength to protect the internal perovskite cell 303 from external impacts or environmental factors such as dust, moisture, and temperature changes.

[0057] The perovskite solar cell 303 is used for photoelectric conversion. Specifically, the perovskite solar cell 303 may include a first electrode layer, a second electrode layer, a hole transport layer, an electron transport layer, and a perovskite layer located between the first and second electrode layers. The perovskite layer can be understood as a light-absorbing layer in the perovskite solar cell 303, used to absorb light energy and generate electron-hole pairs under the excitation of light energy. The perovskite layer is composed of perovskite materials, such as methylamine lead iodide perovskite (CH3NH3PbI3). The first and second electrode layers are used to transport different types of charge carriers, thereby forming a current between the first and second electrode layers. For example, electrons can flow to the second electrode layer, while positive holes flow to the first electrode layer. In this case, the first electrode layer can be the positive electrode of the perovskite solar cell 303, and can include a conductive metal material, such as aluminum or silver. The second electrode layer can be the negative electrode of the perovskite solar cell 303, and can be a transparent conductive layer, which can include a conductive oxide material, such as tin oxide or indium tin oxide. The hole transport layer is located between the first electrode layer and the perovskite layer, and is used to transport positive holes generated in the perovskite layer to the first electrode layer; the electron transport layer is located between the second electrode layer and the perovskite layer, and is used to transport electrons generated in the perovskite photoelectric layer to the second electrode layer, thereby generating photogenerated carriers between the first electrode layer and the second electrode layer, thus achieving efficient photoelectric conversion and improving the power generation efficiency of photovoltaic doors and windows.

[0058] The second conductive glass 302 can be specifically understood as the back glass of the photovoltaic panel 3. The second conductive glass 302 enhances the overall strength of the photovoltaic panel 3 and forms a sealed structure to prevent environmental factors such as water vapor and oxygen from affecting the perovskite cell 303, thereby improving the durability of the photovoltaic door and window. The surface of the second conductive glass 302 can be coated with a transparent conductive oxide, such as fluorine-doped tin oxide (FTO) or indium tin oxide (ITO), to collect the photocurrent generated by the perovskite cell 303 and transmit it to the positive conductive strip 41 and negative conductive strip 42 disposed on the second conductive glass 302.

[0059] By setting the photovoltaic panel 3 as a sandwich structure including a first conductive glass 301, a second conductive glass 302, and a perovskite cell 303, it is possible to ensure that the photovoltaic doors and windows generate electricity efficiently while having good light transmittance, mechanical strength, and durability.

[0060] In an optional embodiment, the positive conductive strip 41 and the negative conductive strip 42 can be located on the front and back sides of the photovoltaic panel 3, respectively. That is, the positive conductive strip 41 can be located on the first conductive glass 301 of the photovoltaic panel 3, and the negative conductive strip 42 can be located on the second conductive glass 302 of the photovoltaic panel 3, so that the positive conductive strip 41 and the negative conductive strip 42 can respectively transmit the positive current and the negative current generated by the photovoltaic panel 3.

[0061] In another alternative embodiment, reference continues... Figure 2 The positive conductive strip 41 and the negative conductive strip 42 are located on the same side of the photovoltaic panel 3 and are arranged sequentially along the second direction Y; the second direction Y intersects with the first direction X.

[0062] Specifically, the positive conductive strip 41 and the negative conductive strip 42 can be located on the same side of the photovoltaic panel 3, that is, the positive conductive strip 41 and the negative conductive strip 42 are both located on the first conductive glass 301 of the photovoltaic panel 3, or the positive conductive strip 41 and the negative conductive strip 42 are both located on the second conductive glass 302 of the photovoltaic panel 3. In this case, the positive conductive strip 41 and the negative conductive strip 42 are arranged sequentially along the second direction Y that intersects with the first direction X. By arranging the positive conductive strip 41 and the negative conductive strip 42 sequentially along the direction intersecting with the sliding direction of the door and window frame 2, the first conductive structure 51 fixed in the door and window slide rail 1 and the positive conductive strip 41, and the second conductive structure 52 fixed in the door and window slide rail 1 and the negative conductive strip 42 can always maintain stable electrical contact during the sliding process of the photovoltaic door and window, ensuring continuous current transmission during the sliding process, improving the stability of the photovoltaic door and window during the sliding process, and enhancing the power generation efficiency and reliability of the photovoltaic door and window.

[0063] Optional, continue to refer to Figure 2 The width L1 of the positive electrode conductive strip 41 along the second direction Y is in the range of 2mm≤L1≤10mm; and / or the width L2 of the negative electrode conductive strip 42 along the second direction Y is in the range of 2mm≤L2≤10mm; the second direction Y intersects with the first direction X.

[0064] Specifically, the widths of the positive conductive strip 41 and the negative conductive strip 42 along the second direction Y, which intersects the first direction X, are both between 2mm and 10mm. If the widths of the positive conductive strip 41 and the negative conductive strip 42 are too narrow, the resistance may be too high, affecting the current transmission capacity. It may also result in insufficient contact area between the conductive strip and the conductive structure, making it prone to open circuits during door / window frame 2 failure. If the widths of the positive conductive strip 41 and the negative conductive strip 42 are too wide, they will occupy too much of the photovoltaic panel 3's surface area, affecting the effective power generation area of ​​the photovoltaic panel 3 and reducing the overall photoelectric conversion efficiency of the photovoltaic door / window. By limiting the widths of the positive conductive strip 41 and the negative conductive strip 42 within a suitable range, it is possible to ensure the current transmission capacity of the photovoltaic panel 3 while minimizing shading of the effective light-receiving area of ​​the photovoltaic panel 3, thereby maximizing the photoelectric conversion efficiency of the photovoltaic door / window.

[0065] Optional, Figure 4 This is a side view structural diagram of a photovoltaic door and window provided in an embodiment of this utility model, as shown below. Figure 4 As shown, the thickness T1 of the positive electrode conductive strip 41 is in the range of 0.05mm≤T1≤5mm; and / or, the thickness T2 of the negative electrode conductive strip 42 is in the range of 0.05mm≤T2≤5mm.

[0066] Specifically, the thickness of both the positive conductive strip 41 and the negative conductive strip 42 ranges from 0.05 mm to 5 mm. If the thickness of the positive conductive strip 41 and the negative conductive strip 42 is too narrow, it may lead to excessive resistance, resulting in increased current transmission loss, and is also prone to breakage or deformation due to mechanical stress. If the thickness of the positive conductive strip 41 and the negative conductive strip 42 is too thick, material consumption increases, leading to higher costs, and may also cause the conductive strips to be too heavy, affecting the smoothness of the sliding of the door and window frame 2. By limiting the thickness of the positive conductive strip 41 and the negative conductive strip 42 to a suitable range, it is ensured that the positive conductive strip 41 and the negative conductive strip 42 provide good conductivity without significantly increasing the weight of the door and window. This ensures continuous current transmission during the sliding process of the photovoltaic door and window, improves the stability of the photovoltaic door and window during the sliding process, and enhances the power generation efficiency and reliability of the photovoltaic door and window.

[0067] Optional, Figure 5 This is a schematic diagram of another photovoltaic door / window structure provided in this embodiment of the present invention, as shown below. Figure 5 As shown, when a photovoltaic door and window includes multiple door and window frames 2 and multiple photovoltaic panels 3, each photovoltaic panel 3 is installed in a corresponding manner within the door and window frame 2; the positive conductive strip 41 of each photovoltaic panel 3 is electrically connected to the same first cable 502 through each first conductive pin 501 in each first conductive structure 51; the negative conductive strip 42 of each photovoltaic panel 3 is electrically connected to the same second cable 504 through each second conductive pin 503 in each second conductive structure 52.

[0068] For details, please refer to [link / reference]. Figure 5 When the photovoltaic door and window includes a first door and window frame 21 and a second door and window frame 22, and a first photovoltaic panel 31 and a second photovoltaic panel 32, the first photovoltaic panel 31 is correspondingly disposed in the first door and window frame 21, and the second photovoltaic panel 32 is correspondingly disposed in the second door and window frame 22, so that the first door and window frame 21, the first photovoltaic panel 31, the second door and window frame 22, and the second photovoltaic panel 32 can all slide smoothly along the first direction X. Meanwhile, the first photovoltaic panel 31 is provided with a first positive conductive strip 411 and a first negative conductive strip 421 that are insulated from each other, and the second photovoltaic panel 32 is provided with a second positive conductive strip 412 and a second negative conductive strip 422 that are insulated from each other. The first positive conductive strip 411 is in contact with the first first conductive structure 511, the first negative conductive strip 421 is in contact with the first second conductive structure 521, the second positive conductive strip 412 is in contact with the second first conductive structure 512, and the second negative conductive strip 422 is in contact with the second second conductive structure 522. All three conductive structures 511, 521, 512, and 522 are fixed within the door / window sliding track 1. The first first conductive structure 511 and the first second conductive structure 521 are used to transmit the positive and negative currents generated by the first photovoltaic panel 31, respectively, and the second first conductive structure 512 and the second second conductive structure 522 are used to transmit the positive and negative currents generated by the second photovoltaic panel 32, respectively.

[0069] The first conductive structure 511 includes a first conductive pin 5011, and the second conductive structure 512 includes a second conductive pin 5012. The first conductive pin 5011 and the second conductive pin 5012 are electrically connected to the same first cable 502. The first conductive structure 521 includes a first conductive pin 5031, and the second conductive structure 522 includes a second conductive pin 5032. The first conductive pin 5031 and the second conductive pin 5032 are electrically connected to the same second cable 504, so that the first photovoltaic panel 31 and the second photovoltaic panel 32 are connected in parallel. That is, the first photovoltaic panel 31 and the second photovoltaic panel 32 can generate electricity independently. Even if one of the first photovoltaic panel 31 or the second photovoltaic panel 32 is partially blocked, attenuated, or damaged, the other photovoltaic panel can still transmit the positive and negative current generated by the photovoltaic panel to the external load 00 through the first cable 502 and the second cable 504, thereby improving the overall stability and reliability of the photovoltaic door and window. In addition, photovoltaic doors and windows can ensure continuous current transmission for each photovoltaic panel during the simultaneous sliding process, thereby effectively improving the power generation efficiency, reliability and applicability of photovoltaic doors and windows.

[0070] It is understandable that the first conductive glass 301 in the first photovoltaic panel 31 and the second photovoltaic panel 32 should both face the light-receiving surface so that the first conductive glass 301 can transmit as much sunlight as possible to the perovskite cells 303 in the first photovoltaic panel 31 and the second photovoltaic panel 32, thereby improving the photovoltaic conversion efficiency of the photovoltaic doors and windows. It is also understood that the first positive conductive strip 411 and the first negative conductive strip 421 of the first photovoltaic panel 31, and the second positive conductive strip 412 and the second negative conductive strip 422 of the second photovoltaic panel 32 are respectively disposed on opposite sides of their respective photovoltaic panels. That is, when the first positive conductive strip 411 and the first negative conductive strip 421 of the first photovoltaic panel 31 are disposed on the first conductive glass 301 of the first photovoltaic panel 31, the second positive conductive strip 412 and the second negative conductive strip 422 of the second photovoltaic panel 32 should be disposed on the second conductive glass 302 of the second photovoltaic panel 32; when the first positive conductive strip 411 and the first negative conductive strip 421 of the first photovoltaic panel 31 are disposed on the second conductive glass 302 of the first photovoltaic panel 31... The second positive conductive strip 412 and the second negative conductive strip 422 of the second photovoltaic panel 32 should be disposed on the first conductive glass 301 of the second photovoltaic panel 31, so that the first positive conductive strip 411, the first negative conductive strip 421, the second positive conductive strip 412, the second negative conductive strip 422, the first first conductive structure 511, the first second conductive structure 521, the second first conductive structure 512, and the second second conductive structure 522 will not affect the simultaneous sliding of the first photovoltaic panel 31 and the second photovoltaic panel 32 in the door and window slide rail 1, thereby enabling the photovoltaic door and window to ensure the continuous transmission of current in each photovoltaic panel during the simultaneous sliding of multiple photovoltaic panels, effectively improving the power generation efficiency, reliability, and applicability of the photovoltaic door and window.

[0071] Optional, Figure 6 This is a side view structural diagram of another photovoltaic door and window provided in this embodiment of the present invention, as shown below. Figure 6 As shown, the door and window sliding rail 1 includes a track 101 and a housing 102; the door and window frame 2 is slidably connected to the track 101; the housing 102 surrounds part of the door and window frame 2 and part of the photovoltaic panel 3, and the positive electrode conductive strip 41 and the negative electrode conductive strip 42 disposed on the photovoltaic panel 3 are located inside the housing 102.

[0072] The door and window frame 2 is slidably connected to the track 101. The track 101 is used to provide a stable sliding path for the door and window frame 2, so as to ensure that the door and window frame 2 and the photovoltaic panel 3 can move smoothly within the track 101. The track 101 can be made of aluminum alloy or stainless steel, which can improve the wear resistance and weather resistance of the track and extend the service life of the photovoltaic door and window.

[0073] The outer casing 102 surrounds part of the door / window frame 2 and part of the photovoltaic panel 3. The positive conductive strip 41 and negative conductive strip 42, which are disposed on the photovoltaic panel 3, are located inside the outer casing 102. This allows the outer casing 102 to effectively prevent the positive conductive strip 41 and negative conductive strip 42 from being affected by external environmental factors such as dust, moisture, and corrosive gases. This avoids poor contact caused by oxidation or contamination of the positive conductive strip 41 and negative conductive strip 42, thus improving the stability of current transmission in the photovoltaic door / window. In addition, the outer casing 102 can reduce damage to the positive conductive strip 41 and negative conductive strip 42, as well as the first conductive structure 51 and the second conductive structure 52, caused by external mechanical friction, thereby improving the durability, safety, and stability of the photovoltaic door / window.

[0074] Optional, continue to refer to Figure 6 The door and window sliding track 1 also includes an insulating protective layer 103; the insulating protective layer 103 is disposed between the outer shell 102 and the photovoltaic panel 3.

[0075] Specifically, the insulating protective layer 103 in the door and window sliding track 1 is disposed between the outer casing 102 and the photovoltaic panel 3, so that the insulating protective layer 103 can effectively block direct contact between the first conductive strip 41, the second conductive strip 42, the first conductive structure 51, and the second conductive structure 52 and the outer casing 102, thereby preventing current leakage and improving the electrical safety of the photovoltaic door and window. For example, the material of the insulating protective layer 103 can be polyimide, polytetrafluoroethylene, silicone layer, or epoxy resin coating, etc., to provide insulation protection for the photovoltaic door and window according to different application environments.

[0076] Optional, continue to refer to Figure 6 The door and window sliding track 1 also includes a shielding plate 104; the outer shell 102 includes an outer shell side 1021 and an outer shell bottom 1022, the outer shell side 1021 surrounds the outer shell bottom 1022, and the first end of the outer shell side 1021 is connected to the outer shell bottom 1022; the shielding plate 104 includes a first shielding plate 1041 and a second shielding plate 1042 opposite to each other; the first shielding plate 1041 and the second shielding plate 1042 are located on opposite sides of the door and window frame 2, and the first shielding plate 1041 and the second shielding plate 1042 are assembled on the second end of the outer shell side 1021; the shielding plate 104 and the outer shell 102 form an accommodating space; the positive electrode conductive strip 41 and the negative electrode conductive strip 42 are located in the accommodating space; wherein, the first end and the second end of the outer shell side 1021 are opposite ends of the outer shell side 1021.

[0077] Specifically, the outer casing 102 of the door and window sliding track 1 includes a casing side 1021 and a casing bottom 1022. The casing side 1021 surrounds the casing bottom 1022, and the first end of the casing side 1021 is connected to the casing bottom 1022, so that the casing 102 can surround part of the door and window frame 2 and part of the photovoltaic panel 3, so that the casing 102 can effectively prevent the external environment from affecting the positive conductive strip 41 and the negative conductive strip 42. In addition, the shielding plate 104 includes a first shielding plate 1041 and a second shielding plate 1042 located on opposite sides of the door and window frame 2, and the first shielding plate 1041 and the second shielding plate 1042 are assembled at the second end of the casing side 1021 opposite to the first end of the casing side 1021, so that the shielding plate 104 and the casing 102 form a receiving space, and the positive conductive strip 41 and the negative conductive strip 42 are located in the receiving space. The enclosure formed by the shielding plate 104 and the outer shell 102 prevents external environmental factors, such as dust, moisture, rain, and sandstorms, from directly affecting the positive conductive strip 41 and the negative conductive strip 42. This reduces oxidation, corrosion, and aging of the positive and negative conductive strips 41 and 42 caused by environmental erosion, improving the long-term stability and reliability of the photovoltaic window. The enclosure also provides a sealed support environment, reducing displacement, bending, or detachment of the positive and negative conductive strips 41 and 42 due to external forces. This ensures continuous current transmission during the sliding process of the photovoltaic window, improving its stability and enhancing its power generation efficiency and reliability.

[0078] Furthermore, the enclosure formed by the shielding plate 104 and the outer casing 102 can enclose all electrical connections of the photovoltaic window / door within, effectively concealing the wiring and making the photovoltaic window / door more concise and aesthetically pleasing. Simultaneously, the outer casing 102 and the shielding plate 104 can be made of different materials, colors, and surface treatments, such as brushed metal, spraying, and glass lamination, allowing for customized designs to suit different architectural styles. This enables the photovoltaic window / door to better integrate into the building's appearance, achieving a combination of functionality and aesthetics.
