Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, provide a detailed description of the backpack-style multifunctional flexible perovskite solar cell tent of this utility model.

[0028] Example 1

[0029] Currently, flexible perovskite solar photovoltaic thin films, as a type of solar cell, have broad application prospects due to their advantages such as simple manufacturing process and low cost. For example... Figure 1 As shown, flexible perovskite solar photovoltaic films are generally composed of a multi-layered composite structure, sequentially including a flexible substrate layer 1, a transparent electrode layer 2, a first carrier transport layer 3, a perovskite light absorption layer 4, a second carrier transport layer 5, a metal electrode layer 6, an encapsulation intermediate layer 7, and a backplane 8. The flexible substrate layer 1 is the basic supporting part of the solar cell and can be made of polymer films such as polyethylene terephthalate (PET), polyimide (PI), or PEN, possessing good optical transparency, mechanical properties, and chemical stability, providing good physical support for the cell. The transparent electrode layer 2 can be made of indium tin oxide (ITO), fluorine-doped tin oxide (FTO), or tungsten-doped tin oxide (IWO), which have high conductivity and good optical transparency, and are compatible with various perovskite cell structures and materials. The first carrier transport layer 3 is a hole transport layer, and the second carrier transport layer 5 is an electron transport layer; or vice versa, with the first carrier transport layer 3 being an electron transport layer and the second carrier transport layer 5 being a hole transport layer, which can be selected according to the application. The hole transport layer can be made of materials such as NiOx, Spiro-OMeTAD, and PTAA, while the electron transport layer can be made of materials such as C60, SnOx, TiOx, and BCP. The perovskite light absorption layer 4, as the core part of the battery, is used to absorb light energy and generate electron-hole pairs. By changing the composition of the perovskite material (such as the replacement or ratio adjustment of cations and anions), the photoelectric conversion efficiency can be improved. The metal electrode layer 6 uses a metal with good conductivity (such as gold, silver, copper, carbon, etc.) or a metal oxide with metallic properties (such as ITO, IWO, etc.), or a composite electrode of metal and metal oxide. The metal material is prepared by thermal evaporation or magnetron sputtering deposition, while the metal oxide is usually prepared by magnetron sputtering. The encapsulation intermediate layer 7 is made of organic polymers such as PVB and PI, and is prepared by technologies such as solution spin coating or ALD. The packaging backplane 8 is encapsulated by lamination or bonding, and common materials include PET composite film and aluminum foil. It provides mechanical support and blocks water and oxygen intrusion, achieves electrical insulation, and has good weather resistance.

[0030] like Figure 2As shown, this embodiment provides a backpack-style multifunctional flexible perovskite solar cell tent, including a tent body 10 and several tent poles 20 passing through the tent body 10. When the tent body 10 is unfolded and supported, it is cone-shaped with a smaller top and a larger bottom, including a front tent surface 11, a rear tent surface, a left tent surface, a right tent surface 12, a tent top surface 13, and a tent bottom surface. The front tent surface 11 is provided with an entrance 111 and a door curtain 112. The left tent surface and the right tent surface 12 are provided with windows and curtains 121. Two shoulder straps 30 are connected to the rear tent surface. The front tent surface 11, the left tent surface, the right tent surface 12, and the rear tent surface are each provided with two zipper toothed straps 14 extending from the tent top surface 13 to the tent bottom surface. The backpack-style multi-functional flexible solar cell tent also includes an energy storage battery 40. A flexible perovskite solar photovoltaic film 50, electrically connected to the energy storage battery 40, is covered on the outer surface of the door curtain 112 and curtain 121 facing the tent body 10. The flexible perovskite solar photovoltaic film 50 is detachably connected to the door curtain 112 / curtain 121 via Velcro, and the flexible perovskite solar photovoltaic film 50 on the door curtain 112 and curtain 121 is located between two zipper teeth 14 on the same side. Two adjacent zipper teeth 14 on different sides of the tent body 10 are mutually compatible and detachably connected via a zipper pull.

[0031] Specifically, the tent body 10 is made of nylon tent fabric, which is lightweight, wear-resistant, waterproof, and quick-drying, making it suitable for various complex environments. Fixing straps are sewn at the joints of the front tent panel 11, left tent panel, rear tent panel, and right tent panel 12 of the tent body 10, allowing the tent poles 20 to pass through. The tent poles 20 are telescopic poles used to support the tent body 10 and ensure the stability of the tent during use. In this embodiment, the tent poles 20 are made of carbon fiber tubing, which is lightweight, highly stable, and easy to carry and store. The back of the flexible perovskite solar photovoltaic film 50 and the surface of the curtain 112 / curtain 121 are respectively fitted with hook and loop fasteners, allowing for flexible adjustment of the adhesive position and angle of the flexible perovskite solar photovoltaic film 50 according to the tent's location and lighting conditions. This facilitates disassembly, cleaning, and maintenance, minimizes damage to the surface of the tent body 10, and extends the tent's lifespan. The energy storage battery 40 is placed inside the tent body 10 and connected to the flexible perovskite solar photovoltaic film 50 via lightweight flexible conductive lines (such as flexible copper foil or conductive fibers). This allows the electrical energy generated by the flexible perovskite solar photovoltaic film 50 to be stored in the energy storage battery 40, ensuring the stability and safety of power transmission. The energy storage battery 40 also has a USB interface and a power socket, making it convenient for users to use various electrical appliances, such as lights, heating pads, and communication devices.

[0032] Furthermore, the two zipper teeth 14 on the front tent panel 11 are the front left zipper tooth 14a and the front right zipper tooth 14b, the two zipper teeth 14 on the left tent panel are the left front zipper tooth 14 and the left rear zipper tooth 14, the two zipper teeth 14 on the right tent panel 12 are the right front zipper tooth 14c and the right rear zipper tooth 14d, and the two zipper teeth 14 on the rear tent panel are the rear left zipper tooth 14 and the rear right zipper tooth 14. The two zipper teeth 14 located on the same side of the tent body 10 are symmetrically arranged, and the distance between the upper ends of the two zipper teeth 14 is less than or equal to the distance between their lower ends. When folded up, the front left zipper toothed belt 14a and the left front zipper toothed belt, the front right zipper toothed belt 14b and the right front zipper toothed belt 14c, the rear left zipper toothed belt and the left rear zipper toothed belt, and the rear right zipper toothed belt and the right rear zipper toothed belt 14d are respectively engaged by a zipper head, thereby folding the tent body 10 into a backpack shape, with the tent top surface 13 serving as the bottom surface of the backpack.

[0033] Furthermore, one end of the carrying strap 30 is connected near the bottom of the tent, and the other end is connected near the top of the tent 13. The length can be adjusted using conventional methods such as setting a connecting buckle. The section of the carrying strap 30 near the bottom of the tent also has a cushioning layer, which can be made of flexible padding materials such as sponge, to distribute shoulder pressure when carrying the load and improve the user experience.

[0034] Furthermore, the tent body 10 is also equipped with several sensors 60 and a display panel 70. The display panel 70 is electrically connected to the energy storage battery 40 and / or the flexible perovskite solar photovoltaic film 50, and is powered by the energy storage battery 40 and / or the flexible perovskite solar photovoltaic film 50. In this embodiment, the display panel 70 is an organic light-emitting diode (OLED) flexible display obtained by arranging and connecting light-emitting sub-units in an array. The sensors 60 include temperature sensors, humidity sensors, etc., and are installed on the curtain 121 and the door curtain 112. The display panel 70 is also equipped with a Bluetooth module, which can communicate with devices such as temperature sensors, humidity sensors, and energy storage batteries 40 via Bluetooth, and can display information such as temperature, humidity, and energy storage battery power in real time. The display panel 70 can also connect to electronic devices such as mobile phones via Bluetooth to transmit information to the mobile phone for easy viewing by the user.

[0035] When using the backpack-style multifunctional flexible perovskite solar cell tent of this embodiment, first unfold the tent body 10, and support and fix it to the ground at the four corners with tent poles 20. After the door curtain 112 and / or curtain 121 on the tent body 10 are opened, their lower edges can be supported and fixed by several support poles to ensure that the entrance 111 and window are unobstructed. At the same time, the door curtain 112 and curtain 121 can also serve as sunshade cloths. Further adjust the position and angle of the flexible perovskite solar photovoltaic film 50 on the door curtain 112 and curtain 121 according to the sunlight conditions so that it can receive sunlight to the maximum extent and convert light energy into electrical energy for use. At the same time, it also enhances the sunshade effect of the door curtain 112 and curtain 121.

[0036] When it is necessary to fold up the backpack-style multifunctional flexible perovskite solar cell tent of this embodiment, firstly, the tent poles 20 are folded up and shortened. Then, the zipper teeth 14 on the four sides of the tent body 10 are engaged one by one by the zipper pulls, thereby folding up the four corners of the tent body 10 and shrinking it into a backpack shape. Then, the tent body 10 is flipped over so that the smaller tent bottom is at the bottom, serving as the bottom of the backpack. The tent poles 20 can be stored in the backpack or adjusted to a suitable length to serve as a frame support inside the backpack. Other outdoor supplies can also be placed inside the backpack. When it is necessary to move to another location, the user can carry the backpack formed by folding up the tent on their back using the shoulder straps 30. The flexible perovskite solar photovoltaic film 50 located on the front tent surface 11, left tent surface, and right tent surface 12 of the tent body 10 is exposed outside the backpack and can still receive sunlight and convert it into electrical energy for storage during movement.

[0037] In summary, the backpack-style multifunctional flexible perovskite solar cell tent of this embodiment has a simple overall structure. The flexible perovskite solar photovoltaic film 50 itself is thin and lightweight with good bending performance. After folding and storage, the tent is small in size and light in weight, making it convenient to carry and transport. Compared with traditional tents with rigid solar panels, the tent using the flexible perovskite solar photovoltaic film 50 can reduce the overall weight by 30% to 80%. The flexible perovskite solar photovoltaic film 50 installed on the tent door curtain 112 and curtain 121 can collect sunlight over a large area and convert it into electrical energy. It can also be used as a sunshade to achieve the function of sunshade and heat insulation, realizing the organic combination of power generation and sunshade. Under sunlight conditions, the tent can continuously collect solar energy and convert it into electrical energy for storage, whether unfolded or folded. It can power various electrical devices inside and outside the tent around the clock, such as mobile phones, GPS devices, lights, electric heating pads, etc., greatly reducing the demand for external power during outdoor activities and making it more energy-efficient and environmentally friendly. Furthermore, the tent structure of this embodiment can be easily transformed into a wearable backpack, which is easy to assemble and disassemble, highly flexible, and easy to carry, making it suitable for outdoor activities such as hiking, cycling, mountaineering, and wilderness exploration.
