Technical Field
[0001] This utility model relates to the field of photovoltaic building technology, specifically a perovskite photovoltaic roof. Background Art
[0002] Perovskite photovoltaic materials have become a research hotspot in the photovoltaic field due to their high photoelectric conversion efficiency and tunable bandgap characteristics. Among them, photovoltaic rooftops have become an important application area for solar cells because of their advantages such as not occupying additional land and being ready to use immediately.
[0003] A search revealed Chinese patent application number CN202410455314.4, which relates to a perovskite photovoltaic building roof and its manufacturing method. The roof roof includes a roof substrate; a buffer layer disposed on the roof substrate; a perovskite photovoltaic layer disposed on the buffer layer; the perovskite photovoltaic layer is grown on the buffer layer using vacuum deposition technology to form the perovskite photovoltaic building roof; or, it includes a flexible perovskite photovoltaic thin film disposed on the buffer layer; the flexible perovskite photovoltaic thin film is prepared and then bonded to the buffer layer to form the perovskite photovoltaic building roof. This invention allows the perovskite photovoltaic layer to be better integrated into the building, reducing the impact on the building structure, lowering installation difficulty and costs, and potentially resulting in better aesthetics. It also boasts high reliability and is faster and more efficient to install than existing photovoltaic module installation methods. It achieves high-efficiency energy conversion while being lightweight, aesthetically pleasing, and easy to install.
[0004] Existing perovskite photovoltaic roofs guide rainwater away from the roof of the photovoltaic sunroom through water channels. However, the construction of water channels requires a relatively robust load-bearing structure for the photovoltaic sunroom, which increases the load-bearing requirements. Furthermore, the waterproofing of the water channels involves complicated maintenance and is not suitable for long-term use. Therefore, we need to propose a perovskite photovoltaic roof to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a perovskite photovoltaic roof that incorporates a photovoltaic waterproof component and a waterproof barrier umbrella. By connecting the fixing component and the photovoltaic waterproof component, a rainproof and water-resistant layer is formed on the photovoltaic sunroom body, preventing rainwater from penetrating into the sunroom body. Simultaneously, the waterproof barrier umbrella, positioned above the junction of the fixing component and the photovoltaic waterproof component, prevents rainwater from flowing into the photovoltaic sunroom body through the gap between them. This design eliminates the need to increase the load-bearing requirements of the photovoltaic sunroom during construction and installation, and maintenance only requires applying waterproof sealant between each pair of adjacent perovskite photovoltaic panels. Long-term maintenance costs are low, thus solving the problems mentioned in the background art.

[0007] The photovoltaic waterproof component includes four perovskite photovoltaic panels. The lower ends of the four perovskite photovoltaic panels are fixed to the upper end of the photovoltaic sunroom body. The four perovskite photovoltaic panels work together to form a water-blocking protective shell for the photovoltaic panels. Each pair of adjacent perovskite photovoltaic panels is sealed and bonded together with waterproof adhesive.
[0008] Preferably, each perovskite photovoltaic panel has two fixing ribs welded to its lower end, and the fixing ribs have fixing holes, in which fixing screws are slidably connected.

[0011] Preferably, a positioning plate is integrally formed at the upper end of the supporting rib, a plurality of sliding sleeves are embedded on the positioning plate, a plurality of supporting columns are integrally formed at the upper end of the positioning plate, the waterproof barrier umbrella is fixed to the positioning plate by the plurality of supporting columns, the length of the waterproof barrier umbrella is greater than the length of the positioning plate, and the width of the waterproof barrier umbrella is greater than the width of the positioning plate.
[0012] Preferably, the upper end of the perovskite photovoltaic panel is fixed with a positioning rib, and a positioning screw is fixed on the positioning rib. One end of the positioning screw passes through a sliding sleeve and is threadedly connected to two positioning nuts of the same structure.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] This invention incorporates a photovoltaic waterproof component and a waterproof barrier umbrella. By connecting and fixing the photovoltaic waterproof component to the photovoltaic sunroom body, a rainproof and water-proof layer is formed without affecting the light transmission of the perovskite photovoltaic panels, preventing rainwater from penetrating into the photovoltaic sunroom body. Simultaneously, the waterproof barrier umbrella, positioned above the junction of the connecting and fixing component and the photovoltaic waterproof component, prevents rainwater from flowing into the photovoltaic sunroom body through the gap between them. This design eliminates the need to increase the load-bearing requirements of the photovoltaic sunroom during construction and installation, and maintenance only requires applying waterproof sealant between each pair of adjacent perovskite photovoltaic panels, resulting in low maintenance costs over long-term use.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] Please see Figure 1-3 This utility model provides a technical solution: a perovskite photovoltaic roof, including a photovoltaic sunroom body 100, on which photovoltaic waterproof components 200 and waterproof barrier umbrellas 300 for preventing rainwater penetration are installed on four sets of support structures. The waterproof barrier umbrellas 300 are frustoconical in shape and located above the photovoltaic waterproof components 200. The photovoltaic waterproof components 200 and the waterproof barrier umbrellas 300 are connected by connecting and fixing components.
[0021] The photovoltaic waterproof component 200 includes four perovskite photovoltaic panels 201. The lower ends of the four perovskite photovoltaic panels 201 are fixed to the upper end of the photovoltaic sunroom body 100. The four perovskite photovoltaic panels 201 work together to form a photovoltaic panel water-blocking protective shell. Each pair of adjacent perovskite photovoltaic panels 201 are sealed and bonded together with waterproof adhesive.
[0022] By connecting the fixing component and the photovoltaic waterproof component 200 on the photovoltaic sunroom body 100, a rainproof and waterproof layer is formed without affecting the light transmission of the perovskite photovoltaic panel 201, preventing rainwater from penetrating into the photovoltaic sunroom body 100. At the same time, the waterproof barrier umbrella 300 is located above the joint between the fixing component and the photovoltaic waterproof component 200 to prevent rainwater from flowing into the photovoltaic sunroom body 100 through the gap between the fixing component and the photovoltaic waterproof component 200. This means that the load-bearing requirements of the photovoltaic sunroom do not need to be increased during the construction and installation of this device, and during maintenance, only waterproof sealant needs to be applied between each two adjacent perovskite photovoltaic panels 201. The maintenance cost is low in the long term.
[0023] Two fixing stiffeners 202 are welded to the lower end of each perovskite photovoltaic panel 201. Fixing holes are provided on the fixing stiffeners 202, and fixing screws 203 are slidably connected in the fixing holes.
[0024] The lower end of the fixing screw 203 is fixed to the upper end of the photovoltaic sunroom body 100. The fixing screw 203 is threaded to a fixing nut 204 at one end that passes through the fixing hole. By twisting the fixing nut 204, the fixing rib plate 202 is clamped between the fixing nuts 204 in the photovoltaic sunroom body 100, thereby fixing the lower end of the perovskite photovoltaic panel 201.
[0025] The connecting and fixing components include a load-bearing rib plate 401, which is embedded in the upper end of the photovoltaic sunroom body 100. A support rib 402 is integrally formed on the upper end of the load-bearing rib plate 401.
[0026] The upper end of the supporting rib 402 is integrally formed with a positioning plate 403, and multiple sliding sleeves 404 are embedded on the positioning plate 403. Multiple support columns 405 are integrally formed on the upper end of the positioning plate 403. The waterproof barrier umbrella 300 is fixed to the positioning plate 403 through the multiple support columns 405. The length of the waterproof barrier umbrella 300 is greater than the length of the positioning plate 403. The width of the waterproof barrier umbrella 300 is greater than the width of the positioning plate 403 to prevent rainwater from entering the photovoltaic sunroom body 100 through the gap between the positioning plate 403 and the perovskite photovoltaic panel 201.
[0027] A positioning rib plate 205 is fixed to the upper end of the perovskite photovoltaic panel 201. A positioning screw 206 is fixed to the positioning rib plate 205. One end of the positioning screw 206 passes through the sliding sleeve 404 and is threaded to two positioning nuts 207 of the same structure. The two positioning nuts 207 of the same structure fix the upper end of the perovskite photovoltaic panel 201 to the positioning plate 403 to prevent the perovskite photovoltaic panel 201 from falling off the positioning plate 403.
[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
