[0036] The present invention provides a photovoltaic-powered bicycle 100 .

[0037] See also Figure 1 In one embodiment of the present invention, the photovoltaic-powered bicycle 100 includes a vehicle body, on-board electronic equipment, and at least one perovskite photovoltaic module 3, and the on-board electronic equipment is mounted on the vehicle body. All perovskite photovoltaic modules 3 are mounted on the vehicle body and electrically connected to the on-board electronic equipment. The perovskite photovoltaic module 3 has a light incident surface, which faces the outside of the vehicle body. The light incident surface can be understood as the surface on which the perovskite photovoltaic module 3 receives light to generate electricity. Among them, the efficiency of the perovskite photovoltaic module 3 is greater than or equal to 17.5%, and the total area of ​​the light incident surfaces of all perovskite photovoltaic modules 3 is greater than or equal to 400 cm 2 The total area of ​​the light incident surfaces of all the perovskite photovoltaic modules 3 can be understood as the sum of the areas of the light incident surfaces of all the perovskite photovoltaic modules 3 on the vehicle body.

[0038] In the technical solution of the present invention, the perovskite photovoltaic material is a direct bandgap semiconductor material with a high absorption coefficient and high photoelectric conversion efficiency, which can convert full-band light into electrical energy output. Compared with the crystalline silicon photovoltaic module, the perovskite photovoltaic module 3 has a higher light absorption capacity, can effectively absorb light under weak light conditions, and can still maintain a high energy conversion efficiency under low light intensity. This means that the perovskite photovoltaic module 3 generates more electricity than the crystalline silicon photovoltaic module under weak light conditions such as early morning, evening or under the shade of trees. The efficiency of the perovskite photovoltaic module 3 is greater than or equal to 17.5%, and the total area of ​​the light incident surface of all perovskite photovoltaic modules 3 is greater than or equal to 400 cm 2 , can provide more power generation, which can provide a more stable power supply for shared bicycles, which are often parked under the shade of trees or eaves, thereby reducing the probability of shared bicycles failing due to low power generation efficiency. It can be understood that the efficiency of the perovskite photovoltaic module 3 is greater than or equal to 17.5%, and the total area of ​​the light-entering surface of all perovskite photovoltaic modules 3 is greater than or equal to 400cm 2 , in a low-light environment, the comprehensive power generation efficiency can at least meet the minimum power demand of one on-board electronic device of a shared bicycle.

[0039] Specifically, perovskite photovoltaic materials have a high absorption coefficient and excellent photoelectric conversion efficiency. Under the same lighting conditions, perovskite photovoltaic modules 3 can generate more electricity, meaning they can maintain high power generation efficiency even in low-light conditions such as early morning, evening, or under the shade of trees. This provides a more stable power supply for devices such as shared bicycles, which are often parked in the shade of trees or under roofs, thereby reducing the chance of shared bicycles failing due to inefficient power generation. Furthermore, the electrical performance parameters of perovskite photovoltaic modules 3 can be quickly adjusted to achieve current and voltage adjustments through a simple laser scribing pattern, meeting the charging needs of various consumer electronics. The overall manufacturing cost is lower than that of existing crystalline silicon photovoltaic modules, simplifying the manufacturing process and facilitating installation. Maintenance and replacement costs are also significantly reduced, achieving cost reduction and efficiency improvement. In bicycle applications, perovskite photovoltaic modules 3 have a lower failure rate and low ongoing operation and maintenance costs. This technology, which combines perovskite photovoltaic modules 3 with shared bicycles, not only improves the energy self-sufficiency of shared bicycles and reduces their dependence on external charging facilities, but also significantly reduces operating costs, improves user experience, and provides a more reliable and economical solution for shared bicycle operating companies.

[0040] It should be noted that the perovskite photovoltaic module 3 can be fixedly mounted on the spokes of the wheel 13 of the vehicle body, or can be mounted on the vehicle basket 12 of the vehicle body, or can be mounted on other positions of the vehicle body, and can be set according to actual needs. The number of perovskite photovoltaic modules 3 installed on the vehicle body can be 1, 2, 3, 4, 5, etc. This application does not limit the number of perovskite photovoltaic modules 3, and can be set according to actual needs. The total area of ​​the light-entering surface of all perovskite photovoltaic modules 3 can be 400 cm 2 , 500cm 2 , 600cm 2 , 700cm 2 , 800cm 2 , 900cm 2 , 1000cm 2 etc., which are not listed in this application. The total area of ​​the light incident surface is greater than or equal to 400cm 2 The efficiency of the perovskite photovoltaic module 3 can be 17.5%, 18%, 18.5%, 19%, 19.5%, 20%, 20.5%, 21%, 21.5%, 22%, 22.5%, 23%, 23.5%, 24%, 24.5%, 25%, 25.5%, 26%, 26.5%, 27%, 27.5%, 28%, etc., which are not listed one by one in this application. Its efficiency is greater than or equal to 17.5%.

[0041] Please refer to Figure 1 In one embodiment of the present invention, the vehicle body includes a frame 11 and two wheels 13, and the two wheels 13 are rotatably connected to the frame 11. There are multiple perovskite photovoltaic modules 3, and at least one perovskite photovoltaic module 3 is provided on the side of each wheel 13. The perovskite photovoltaic modules 3 are arranged at circumferential intervals around the rotating shaft of the wheel 13. When the wheel 13 rotates, the perovskite photovoltaic modules 3 can also continuously receive sunlight, thereby generating electricity during riding. In addition, the two wheels 13 occupy most of the area of ​​the vehicle body, and a larger area of ​​perovskite photovoltaic modules 3 can be fixedly installed on the spokes of the wheel 13, thereby further improving the power generation of the photovoltaic-powered bicycle 100.

[0042] Please refer to Figure 1In one embodiment of the present invention, each wheel 13 includes a wheel body, an axle, and two conductive rings. The wheel body is equipped with multiple perovskite photovoltaic modules 3 symmetrically arranged relative to the axle, which can reduce the impact of the addition of the perovskite photovoltaic modules 3 on the dynamic balance of the wheel body. The axle passes through the wheel body and is rotatably connected to the wheel body. The two conductive rings are insulated and fixedly connected to opposite sides of the wheel body. Specifically, an insulating frame can be provided to secure the conductive rings to the wheel body, and the insulating frame can be made of plastic. The two ends of the axle are respectively passed through the two conductive rings and are spaced apart from the conductive rings. The perovskite photovoltaic module 3 has a positive electrode and a negative electrode, with the positive electrode electrically connected to one conductive ring and the negative electrode electrically connected to the other conductive ring. The vehicle body also includes four brushes, which are insulated and fixedly connected to the vehicle frame 11. The four brushes are electrically connected to the on-board electronic equipment. The four brushes are in contact with the four conductive rings in a one-to-one correspondence. When the wheel body drives the conductive rings to rotate, the brushes and the conductive rings rub against each other. With this arrangement, when the perovskite photovoltaic module 3 rotates with the wheel, the conductive ring and brushes can be used to electrically connect the perovskite photovoltaic module 3 to the onboard electronic equipment, thereby enabling the transmission of electricity generated by the perovskite photovoltaic module 3 on the wheel to the onboard electronic equipment during the riding of the photovoltaic-powered bicycle 100. It should be noted that the conductive ring can be made of a conductive metal, such as copper. The brush is a sliding contact element that is smooth, wear-resistant, and has good conductivity. Graphite brushes or metal graphite brushes can be used.

[0043] Please refer to Figure 1 In one embodiment of the present invention, the vehicle body further includes a basket 12, a basket cover 14, and an expansion bracket 15. The basket 12 is mounted on the frame 11. The basket 12 is formed with an upward opening. Perovskite photovoltaic modules 3 are respectively provided on at least three different surfaces within the basket 12, and at least one perovskite photovoltaic module 3 is provided on the outer side of the basket 12. Installing perovskite photovoltaic modules 3 on the basket 12 can effectively utilize the surface space of the basket 12, increase additional power output, and will not affect the riding performance of the bicycle. In addition, the perovskite photovoltaic modules 3 are respectively provided on at least three different surfaces within the basket 12, which can receive light projected into the basket 12 from at least three different directions, thereby improving the utilization rate of light. The perovskite photovoltaic modules 3 are provided on the outer side of the basket 12 to further improve the utilization rate of light, thereby improving the reliability of photovoltaic power generation of the entire photovoltaic-powered bicycle 100.

[0044] Please refer to Figure 3In one embodiment of the present invention, a basket cover 14 is movably connected to the basket 12 and is used to cover the opening; a perovskite photovoltaic module 3 is provided on the side of the basket cover 14 facing away from the basket 12. The basket 12 is formed with an upward opening; the vehicle body further includes a basket cover 14, which is movably connected to the basket 12 and is used to cover the opening; a perovskite photovoltaic module 3 is provided on the side of the basket cover 14 facing away from the basket 12. By integrating the perovskite photovoltaic module 3 on the side of the basket cover 14 facing away from the basket 12, solar energy can be effectively used to generate electricity. Since the basket cover 14 is usually located above the bicycle, it can maximize the reception of sunlight and improve the power generation efficiency of the perovskite photovoltaic module 3. By installing photovoltaic modules on the side walls of the basket 12, the design cleverly utilizes the idle space of the bicycle and increases the area for energy collection without sacrificing the original function of the photovoltaic-powered bicycle 100 or adding additional volume.

[0045] Please refer to Figure 1 In one embodiment of the present invention, an expansion bracket 15 is positioned at the end of the bicycle frame 11 away from the basket 12, and at least one perovskite photovoltaic module 3 is positioned on the side of the expansion bracket 15 facing away from the wheel 13. By mounting the perovskite photovoltaic module 3 on the expansion bracket 15, the design cleverly utilizes the unused space on the bicycle. Furthermore, since the perovskite photovoltaic module 3 mounted on the expansion bracket 15 faces upward, it can maximize sunlight reception and improve its power generation efficiency.

[0046] Please refer to Figure 1 In one embodiment of the present invention, the photovoltaic-powered bicycle 1000 further includes a voltage stabilizer, a control device, and a battery 4. The perovskite photovoltaic module 3 is connected to the control device, the voltage stabilizer is electrically connected to the control device, the voltage stabilizer is electrically connected to the battery 4, and the battery 4 is electrically connected to the onboard electronic equipment. A voltage stabilizer is a device used to maintain a fixed output voltage. Its main function is to regulate changes in input voltage to ensure a stable output voltage, thereby protecting the connected battery from voltage fluctuations. Battery 4 is used to store the electrical energy generated by the perovskite photovoltaic module 3 under sunlight, thereby ensuring that the onboard electronic equipment can operate normally in the absence of sunlight. The presence of battery 4 improves the energy self-sufficiency of the entire system, reduces dependence on external power sources, and thus improves the photovoltaic-powered bicycle 100's ability to operate stably in various environments. The control device is used to control the process of charging the battery 4 with the electrical energy generated by the perovskite photovoltaic module 3. It can regulate the power transmitted from the perovskite photovoltaic module 3 to the battery 4, thereby protecting the battery.

[0047] Please refer to Figure 1In one embodiment of the present invention, the onboard electronic devices include one or more of a computer 21, an electric fan, a mobile phone charger, a light 22, and an electronic lock 25. The electronic lock 25 includes a lock body, an antenna, a GPS receiver, and an IoT card, each mounted on the lock body. The computer 21 displays information such as the shared bicycle's speed, distance traveled, and time, helping users understand their riding status. It draws power from the battery 4 to ensure continuous display of this information. The light 22 includes, but is not limited to, signal lights, warning lights, and illumination lights, and is used to enhance the shared bicycle's visibility at night or in dark environments, while also alerting and providing signals to others and ensuring safe riding. The mobile phone charger 23 provides a USB port or other charging method for users to charge their mobile phones or other electronic devices while riding. The mobile phone charger 23 draws power directly from the battery 4, making it easier for users to maintain device charge while riding. The electronic lock 25 replaces a traditional mechanical lock and is powered by the battery 4. Users can unlock the bicycle using a mobile phone app or a password, improving convenience and safety. The GPS positioning device 24 is used to track the location of shared bikes in real time, making it easier for users to find them and helping operators monitor and manage them. The GPS device requires a continuous power supply to maintain continuous positioning services. The antenna, GPS receiver, and IoT card are integrated into the lock body, optimizing space. The compact design reduces the number of external components and improves aesthetics. Furthermore, integrating components within the lock body enhances security and prevents external intrusion or interference.

[0048] Please refer to Figure 1 In one embodiment of the present invention, the starting voltage received by the control device is greater than or equal to 200mV, the starting power received by the control device is greater than or equal to 10μW, the voltage output by the control device is in the range of 1V to 50V, and the current output by the control device is in the range of 5mA to 2A. With this arrangement, the control device can achieve a cold start in a low-voltage and low-power energy input scenario, and after starting, it can obtain direct current from the perovskite photovoltaic module 3 to charge the battery 4. On the other hand, if the current generated by the perovskite photovoltaic module 3 is directly charged into the battery 4, it is easy to cause damage to the battery 4, seriously reducing the life of the battery. The use of a control device can control the charging current and voltage to ensure that the battery 4 is charged in the optimal state, thereby extending the service life of the battery 4.

[0049] It should be noted that the starting voltage received by the control device can be 200mV, 300mV, 400mV, 500mV, 600mV, etc., which are not listed one by one in this application. The starting voltage received by the control device can be greater than or equal to 200mV. The starting power received by the control device can be 10μW, 20μW, 30μW, 40μW, 50μW, etc., which are not listed one by one in this application. The starting power received by the control device can be greater than or equal to 10μW. The voltage range output by the control device can be 1V, 10V, 20V, 30V, 40V, 50V, etc., which are not listed one by one in this application. The voltage range output by the control device can be 1V to 50V. The current output by the control device can be 5mA, 10mA, 50mA, 1A, 2A, etc., which are not listed one by one in this application. The current range output by the control device can be 5mA to 2A.

[0050] Please refer to Figure 2 In one embodiment of the present invention, the perovskite photovoltaic module 3 includes a cover plate 31, an encapsulant film layer 32, a functional film layer 33, a backing layer 34, and a functional protective layer 35. The encapsulant film layer 32 is provided on the cover plate 31, the functional film layer 33 is provided on the side of the encapsulant film layer 32 facing away from the cover plate 31, the backing layer 34 is provided on the side of the functional film layer 33 facing away from the encapsulant film layer 32, and the functional protective layer 35 is provided on the side of the backing layer 34 facing away from the functional film layer 33. The encapsulant film layer 32 effectively protects the functional film layer 33 within the perovskite photovoltaic module 3, preventing them from being corroded and damaged by external environmental factors such as moisture, oxygen, and temperature changes, thereby extending the service life of the perovskite photovoltaic module 3. The functional protective layer 35 effectively protects the functional film layer 33, preventing it from being damaged by external objects.

[0051] It is understood that the material of the encapsulating film layer 32 can be polyvinyl butyral or butyl rubber. In one embodiment of the present invention, the encapsulating film layer 32 is made of butyl rubber. Butyl rubber has excellent corrosion resistance to most inorganic and organic acids and is resistant to corrosion by chemicals such as acids and bases. It is also resistant to environmental factors such as ultraviolet rays, temperature fluctuations, and humidity, and is not susceptible to aging and degradation. Therefore, butyl rubber is preferably used as the material for the encapsulating film layer 32.

[0052] Please refer to Figure 2 In one embodiment of the present invention, the surface of the functional protection layer 35 facing away from the back layer 34 is a frosted surface, which can easily remove adhesions, effectively solving the problem of difficult removal of small advertisements on the back of the perovskite photovoltaic module 3 when used outdoors.

[0053] Please refer to Figure 2In one embodiment of the present invention, the functional protective layer 35 includes an ethylene-octene copolymer layer and a polyethylene terephthalate layer. The ethylene-octene copolymer layer is disposed on the side of the backplane layer 34 facing away from the functional film layer 33, and the polyethylene terephthalate layer is disposed on the side of the ethylene-octene copolymer layer facing away from the backplane layer 34. The ethylene-octene copolymer layer and the polyethylene terephthalate layer are laminated together. Thus, after undergoing a special surface treatment, the functional protective layer 35 has a high surface hardness that resists scratches and a hydrophobic surface that resists staining. This reduces the likelihood of dirt such as insect carcasses, bird droppings, resin, acid rain stains, and heavy scale remaining on the surface of the perovskite photovoltaic module 3, causing a decrease in light source illumination and thus affecting the power generation efficiency of the perovskite photovoltaic module 3. Lamination between the ethylene-octene copolymer layer and the polyethylene terephthalate layer refers to laminating a layer of frosted PET (polyethylene terephthalate) with POE (ethylene-octene copolymer). It should be noted that lamination molding is an existing technology, and ethylene-octene copolymer and polyethylene terephthalate are also existing materials.
