[0024] 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 outdoor sunshade umbrella based on flexible perovskite solar cells of this utility model.

[0025] Example 1

[0026] Currently, flexible perovskite solar photovoltaic thin films, as a type of solar cell, namely flexible perovskite solar cells, 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 2, a first carrier transport layer 3, a perovskite layer 4, a second carrier transport layer 5, a metal electrode 6, and an encapsulation layer 7. The flexible substrate layer 1 can be made of materials such as polyimide (PI) or polyester film (PET), possessing good mechanical properties and weather resistance. The transparent electrode 2 can be made of materials such as ITO or IZO, forming a high-transmittance electrode through PVD or RPD processes. 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 requirements; the hole transport layer can be made of NiOx material, and the electron transport layer can be made of TiOx material. The perovskite layer 4 uses a multi-cation perovskite material (e.g., FA-Cs-PbI3) to improve photoelectric conversion efficiency and environmental stability. Metal electrode 6 uses metal electrodes such as copper and silver, or composite electrodes, to ensure conductivity and flexibility. Encapsulation layer 7 can be made of inorganic materials such as silicon oxide, aluminum oxide, and silicon nitride, combined with POE or silicone and a water-blocking film.

[0027] like Figure 2 , 3 As shown, this embodiment provides an outdoor sunshade umbrella (hereinafter referred to as an outdoor sunshade umbrella) based on a flexible perovskite solar cell, including a base 10, a supporting main pole 20 disposed on the base 10, umbrella ribs 30 connected to the top of the supporting main pole 20, and an umbrella surface 40 fixed to the umbrella ribs 30. The umbrella surface 40 is covered with a flexible perovskite solar photovoltaic film 41, and a photosensor 42 is installed on the edge of the umbrella surface 40. A lamp 31 is installed on the umbrella ribs 30. A battery (not shown in the figure) is provided in the base 10, and a charging interface 21 is provided on the supporting main pole 20. The flexible perovskite solar photovoltaic film 41 is electrically connected to the charging interface 21 and the battery, and the lamp 31 is electrically connected to the photosensor 42 and the battery.

[0028] Specifically, the umbrella canopy 40 covers the outside of the umbrella ribs 30 and is made of durable and lightweight materials such as nylon or polyester fiber to ensure stability in various weather conditions. A flexible perovskite solar photovoltaic film 41 covers the upward-facing side of the umbrella canopy 40 when it is open. This film is tightly bonded to the umbrella canopy 40 with an adhesive, which not only increases the sun protection performance of the umbrella canopy 40 but also converts solar energy into electrical energy. A photosensor 42 installed on the edge of the umbrella canopy 40 can detect ambient light, facilitating the control of the lighting time of the lamp 31.

[0029] The umbrella ribs 30 are movably connected to the support pole 20, allowing the umbrella canopy 40 to be opened and closed. The umbrella ribs 30 are made of lightweight metal or high-strength plastic to support the umbrella canopy 40 and maintain its shape. The umbrella ribs 30 in this embodiment have the same structure as those in existing outdoor sun umbrellas and will not be described in detail here. A light fixture 31 installed on the umbrella ribs 30 provides illumination at night. In this embodiment, the light fixture 31 uses LED light strips, which are energy-saving, power-efficient, and have a long service life.

[0030] The base 10 can be fixed to the ground using ground stakes or suction cups to ensure the stability of the sun umbrella in strong winds. The base 10 has an embedded battery and control circuitry. The battery stores electrical energy generated by the flexible perovskite solar photovoltaic film 41. In this embodiment, the battery is a rechargeable lithium-ion battery with high energy density and long cycle life. The control circuitry automatically controls the battery to power the lamp 31 and turn on the lighting when the photosensor 42 detects dim ambient light.

[0031] The charging port 21 is located in the middle of the supporting main rod 20. In this embodiment, the charging port 21 integrates a USB-A and USB-C composite port, supports QC4.0 / PD3.1 / PPS multi-protocol adaptive fast charging technology, and is compatible with a wide voltage and current adjustment range from 5V / 1A to 20V / 5A. The charging port 21 intelligently identifies the device's power demand protocol, enabling fully compatible fast charging for various electronic devices such as smartphones, tablets, Bluetooth headsets, portable game consoles, and laptops. Furthermore, the charging port 21 is equipped with a waterproof cover to prevent rainwater or moisture from entering, improving safety.

[0032] In use, the base 10 of the outdoor sun umbrella is fixed to the ground with ground nails or suction cups. The umbrella ribs 30 are opened to unfold the umbrella surface 40, ensuring that the flexible perovskite solar photovoltaic film 41 faces the sunlight and has a smooth, wrinkle-free surface. When exposed to sunlight, the flexible perovskite solar photovoltaic film 41 collects sunlight and converts it into electrical energy to power external devices connected to the charging interface 21. Excess electrical energy is stored in the battery. When the photosensor 42 detects that the ambient light is below a preset threshold, the battery supplies power to the lamp 31, turning it on. Therefore, when users are relaxing under the umbrella, they can charge their mobile phones and other electronic devices through the charging interface 21 without needing a separate power source. At night, the lamp 31 on the umbrella ribs 30 provides illumination, saving energy and making it more convenient to use.

[0033] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
