Description

[Technical Field]

[0001] The present invention relates to a vehicle. [Background technology]

[0002] In recent years, efforts have been made to achieve carbon neutrality by equipping vehicles with solar cells and utilizing the electrical energy generated by the solar cells for driving the vehicle, etc. For example, Patent Document 1 listed below discloses a vehicle in which silicon solar cell modules are placed on the roof and hood of the vehicle, and perovskite solar cell modules are placed on the sides of the doors, thereby improving the amount of power generated by the solar cell modules. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-039144 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the vehicle described in Patent Document 1, the solar cell modules can only be placed on the vehicle body, such as on the roof, hood, and sides of the doors, so there is still room for improvement in the amount of power generated by the solar cell modules.

[0005] The present invention has been made to solve such technical problems, and has an object to provide a vehicle that can further improve the amount of power generation of an on-board solar cell module. [Means for solving the problem]

[0006] The vehicle according to the present invention is a vehicle equipped with a laminated glass for vehicles having two opposing glass plates, and is characterized in that a perovskite solar cell module is sealed between the two glass plates.

[0007] In the vehicle according to the present invention, the perovskite solar cell module is sealed between the two glass plates that form the laminated glass for the vehicle, so that the installation space for the laminated glass for the vehicle can be utilized to install the perovskite solar cell module in that installation space. In this way, by generating power using the perovskite solar cell module installed in the laminated glass for the vehicle in addition to the solar cell module installed in the conventional vehicle body, the amount of power generated by the on-board solar cell module can be further improved. Moreover, because the perovskite solar cell module is thin, light, and flexible, it can be suitably fitted to the shape of the glass plates, and the placement of the perovskite solar cell module has little effect on the laminated glass for the vehicle.

[0008] In the vehicle according to the present invention, the perovskite solar cell module is preferably disposed in the upper area of ​​the vehicle laminated glass as a sunshade, thereby making it possible to utilize the perovskite solar cell module to reduce glare from light.

[0009] Preferably, the vehicle according to the present invention further includes an auxiliary machine and an auxiliary battery, and the perovskite solar cell module and the auxiliary battery are electrically connected via the auxiliary machine. In this way, by directly supplying the electrical energy generated by the perovskite solar cell module to the auxiliary machine, it is possible to prevent energy loss due to conversion compared to when the generated electrical energy is first converted into chemical energy in the auxiliary battery and then converted back into electrical energy for supply to the auxiliary machine.

[0010] Preferably, the vehicle according to the present invention further includes an auxiliary device and an auxiliary battery, and the perovskite solar cell module is electrically connected to the auxiliary device via the auxiliary battery. For example, in the case of an auxiliary device that does not require a constant supply of electrical energy, such as a seat heater or interior illumination, the electrical energy generated by the perovskite solar cell module can be stored in the auxiliary battery, and electrical energy can be supplied from the auxiliary battery when the auxiliary device is to be used. In this way, the cooperation between the perovskite solar cell module and the auxiliary battery makes it possible to adapt to driving a variety of auxiliary devices.

[0011] Furthermore, in the vehicle according to the present invention, it is preferable that the vehicle laminated glass is at least one of a windshield, a front door glass, a rear door glass, and a rear glass. In this case, by providing a perovskite solar cell module on these glasses as necessary, the amount of power generation can be increased. [Effects of the Invention]

[0012] According to the present invention, the amount of power generated by the vehicle-mounted solar cell module can be further improved. [Brief explanation of the drawings]

[Figure 3] FIG. 1 is a diagram illustrating that the perovskite solar cell module and the auxiliary battery are electrically connected via the auxiliary. [Figure 4] FIG. 1 is a diagram illustrating that the perovskite solar cell module is electrically connected to an auxiliary device via an auxiliary battery. DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, an embodiment of a vehicle according to the present invention will be described with reference to the drawings. The vehicle in this embodiment includes automobiles such as passenger cars, buses, and trucks, but the following description will be given taking a passenger car as an example. In the following description, the directions and positions of up / down, left / right, front / rear, and rear are based on the directions as seen by the driver of the vehicle 1.

[0015] Fig. 1 is a perspective view showing a vehicle according to an embodiment. As shown in Fig. 1, the vehicle 1 includes outer panels such as a hood 2, a roof 3, a trunk lid 4, a front fender 5, a rear fender 6, a front door 7, and a rear door 8, as well as a windshield 10, a front door glass 20, a rear door glass 30, and a rear glass 40.

[0016] Laminated glass for vehicles is used for each of the windshield 10, front door glass 20, rear door glass 30, and rear glass 40. The structure of laminated glass for vehicles will be described below using the windshield 10 as an example, as shown in Fig. 2. However, because the structures of the front door glass 20, rear door glass 30, and rear glass 40 are similar to those of the windshield 10, redundant explanations for each will be omitted.

[0017] As shown in Fig. 2, the windshield 10 is disposed between the roof 3 and the dashboard 9, and constitutes the front side of the vehicle interior. The windshield 10 has an outer glass plate 11 located on the outer side of the vehicle, an inner glass plate 12 located on the inner side of the vehicle, and a sealing layer 13 disposed between the outer glass plate 11 and the inner glass plate 12. The outer glass plate 11 and the inner glass plate 12 are formed to have, for example, the same shape, and are disposed opposite each other.

[0018] Known glass plates, heat-absorbing glass, UV-green glass, etc. can be used as the outer glass plate 11 and the inner glass plate 12. However, the outer glass plate 11 and the inner glass plate 12 are formed to have a visible light transmittance that complies with the safety standards of the country in which the automobile is used.

[0019] The thickness of the outer glass plate 11 and the inner glass plate 12 may be the same, but from the viewpoint of realizing a lightweight laminated glass for a vehicle while ensuring the impact resistance performance of the outer glass plate 11 against flying objects, etc., the outer glass plate 11 may be thicker than the inner glass plate 12.

[0020] The sealing layer 13, also called an interlayer film, is formed from a transparent resin sealing material such as polyvinyl butyral resin or ethylene vinyl acetate resin, and bonds the outer glass plate 11 and the inner glass plate 12. In other words, the outer glass plate 11 and the inner glass plate 12 are bonded together by the transparent resin sealing material filled between them.

[0021] Furthermore, the perovskite solar cell module 100 is sealed between the outer glass plate 11 and the inner glass plate 12 by a sealing layer 13. As shown in Figure 2, the perovskite solar cell module 100 has a thin plate shape and is placed in the upper area 10a of the windshield 10 as a sunshade, and is sealed between the outer glass plate 11 and the inner glass plate 12 by the sealing layer 13.

[0022] A known perovskite solar cell module can be used as the perovskite solar cell module 100. For example, the perovskite solar cell module 100 is composed of a transparent substrate, a transparent electrode layer (e.g., ITO (Indium Tin Oxide)), functional layers (e.g., a hole transport layer, a photoelectric conversion layer, and an electron transport layer), and a backside electrode layer (e.g., an Au electrode) laminated in this order on the substrate. The perovskite solar cell module 100 thus configured is placed between an outer glass plate 11 and an inner glass plate 12 with the substrate facing the exterior of the vehicle.

[0023] To be used as a sunshade, a transmissive perovskite solar cell module 100 that can reduce the amount of light transmitted is used for the windshield 10. That is, in this embodiment, the light transmittance of the perovskite solar cell module 100 is adjusted so that the perovskite solar cell module 100 serves as a sunshade. Note that the electrical energy generated by the perovskite solar cell module 100 is supplied to an auxiliary device 110 or an auxiliary battery 102 via a power converter 101, which will be described later.

[0024] As shown in Figure 1, the perovskite solar cell modules 100 are arranged not only on the windshield 10, but also on the upper areas of the front door glasses 20 on both the left and right sides, the upper areas of the rear door glasses 30 on both the left and right sides, and the upper area of ​​the rear glass 40.

[0025] In the vehicle 1 according to this embodiment, the perovskite solar cell module 100 is sealed between two glass plates (for example, the outer glass plate 11 and the inner glass plate 12) that form a laminated glass for the vehicle, and therefore the installation locations of the windshield 10, front door glass 20, rear door glass 30, and rear glass 40 can be utilized to install the perovskite solar cell module 100 in these glass installation locations. In this way, by generating power using the perovskite solar cell modules 100 installed on the windshield 10, front door glass 20, rear door glass 30, and rear glass 40 in addition to the solar cell modules installed on the conventional vehicle body, the amount of power generated by the on-board solar cell module can be further improved, and the effect of improving the fuel efficiency and / or electric power consumption of the vehicle 1 can be expected.

[0026] Furthermore, the perovskite solar cell module 100 is thin, light, and flexible, so it can fit suitably to the shape of the glass plate, and the placement of the perovskite solar cell module 100 has little effect on the windshield 10, front door glass 20, rear door glass 30, and rear glass 40.

[0027] Furthermore, the perovskite solar cell module 100 can be placed as a sunshade in the upper areas of the windshield 10, front door glass 20, rear door glass 30, and rear glass 40, thereby utilizing the perovskite solar cell module 100 to reduce glare from light.

[0028] In this embodiment, the perovskite solar cell module 100 is described as being arranged in the upper area of ​​each of the windshield 10, front door glass 20, rear door glass 30 and rear glass 40, but this is not limited to this, and the perovskite solar cell module 100 may be arranged in the upper area of ​​at least one of the windshield 10, front door glass 20, rear door glass 30 and rear glass 40.

[0029] Furthermore, if privacy glass is installed on the vehicle 1, the perovskite solar cell module 100 can be disposed over the entire privacy glass. Furthermore, the perovskite solar cell module 100 can also be applied to areas where shading is required while creating a sense of openness with a panoramic glass roof.

[0030] The electrical energy generated by the perovskite solar cell module 100 is preferably supplied to an auxiliary device that is driven at a low voltage. In recent years, the number of auxiliary devices has increased with the electrification of automobiles. This has resulted in an increase in the power consumption of the auxiliary devices and an increase in the load on the auxiliary battery. In response to this, in this embodiment, the electrical energy generated by the perovskite solar cell module 100 is supplied directly to the auxiliary device 110 or to the auxiliary battery 102 for charging, thereby covering the power consumption of the auxiliary devices and contributing to reducing the load on the auxiliary battery 102. The supply of electrical energy to the auxiliary device or auxiliary battery will be described below with reference to FIGS. 3 and 4.

[0031] Fig. 3 is a diagram illustrating the electrical connection between the perovskite solar cell module and the auxiliary battery via the auxiliary equipment. As shown in Fig. 3, the vehicle 1 further includes an auxiliary equipment 110 and an auxiliary equipment battery 102 as a power source for the auxiliary equipment system. The auxiliary equipment 110 is, for example, a device that operates at a low voltage, such as a digital rearview mirror 111 or a drive recorder 112.

[0032] The perovskite solar cell module 100 is electrically connected to an auxiliary device 110 via a power converter 101 for adjusting the voltage. The auxiliary device 110 is further electrically connected to an auxiliary battery 102. In this manner, the electrical energy generated by the perovskite solar cell module 100 is directly supplied to the auxiliary device 110 after its voltage is adjusted by the power converter 101.

[0033] 3, as long as the perovskite solar cell module 100 is generating power, the auxiliary device 110 can be driven by the power generated by the perovskite solar cell module 100 without receiving a supply of electrical energy from the auxiliary battery 102. In this way, the power consumption of the auxiliary device 110 can be covered, thereby reducing the load on the auxiliary battery 102 and contributing to an increase in the cruising range of the vehicle 1.

[0034] The digital rearview mirror 111 and the drive recorder 112 are disposed near the windshield 10 or the front door glass 20. Therefore, it is preferable to supply electrical energy generated by the perovskite solar cell module 100 disposed on the windshield 10 and / or the perovskite solar cell module 100 disposed on the front door glass 20 to the digital rearview mirror 111 and the drive recorder 112. In this manner, electrical energy generated by the perovskite solar cell module 100 can be supplied to and consumed by an auxiliary device disposed nearby, thereby shortening the electrical wiring connecting the perovskite solar cell module 100 and the auxiliary device 110. As a result, the electrical energy transport path can be shortened, reducing energy loss and enabling effective use of the electrical energy generated by the perovskite solar cell module 100.

[0035] That is, the auxiliary battery 102 is often placed in the engine compartment, trunk, etc. For example, if the electrical energy generated by the perovskite solar cell module 100 is supplied to and stored in the auxiliary battery 102, the wiring path for connecting to the auxiliary battery 102 becomes longer as the distance to the auxiliary battery 102 increases. This not only increases the complexity of the wiring, but also increases the energy loss during transportation.

[0036] In this embodiment, the electrical energy generated by the perovskite solar cell module 100 arranged on the windshield 10 and / or front door glass 20 is directly supplied to the digital rearview mirror 111 and the drive recorder 112 arranged near the windshield 10 and / or front door glass 20, thereby shortening the wiring path. As a result, wiring costs can be reduced, which contributes to a reduction in the weight of the vehicle 1, and energy loss during transportation can also be suppressed.

[0037] Furthermore, by directly supplying the electrical energy generated by the perovskite solar cell module 100 to the auxiliary equipment 110, it is possible to prevent energy loss due to conversion compared to when the generated electrical energy is first converted into chemical energy in the auxiliary equipment battery 102 and then converted back into electrical energy before being supplied to the auxiliary equipment 110.

[0038] Fig. 4 is a diagram illustrating that the perovskite solar cell module is electrically connected to an auxiliary device via an auxiliary battery. As shown in Fig. 4, the perovskite solar cell module 100 is not electrically connected to the auxiliary device 110 via the power converter 101 as in Fig. 3, but is electrically connected to the auxiliary battery 102 via the power converter 101. The auxiliary device 110 is then electrically connected to the auxiliary battery 102.

[0039] 4, the electrical energy generated by the perovskite solar cell module 100 is stored in the auxiliary battery 102 (in other words, it is used to charge the auxiliary battery 102). In the case shown in FIG. 4, the auxiliary device 110 further includes a seat heater 113 and interior illumination 114 in addition to the digital rearview mirror 111 and the drive recorder 112.

[0040] In the case of accessories that do not require a constant supply of electrical energy, such as seat heaters 113 and interior illumination 114, it is preferable to store the electrical energy generated by the perovskite solar cell module 100 in the auxiliary battery 102 and supply electrical energy from the auxiliary battery 102 when it is desired to use the seat heaters 113 or interior illumination 114. In this way, the perovskite solar cell module 100 and auxiliary battery 102 work together to enable the driving of a variety of accessories.

[0041] Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various design modifications can be made without departing from the spirit of the present invention as defined in the claims. For example, the auxiliary device 110 is not limited to the above-described content. [Explanation of symbols]
