Perovskite layer 4 uses multi-cation perovskite material (such as FA-Cs-PbI3) to improve photoelectric conversion efficiency and environmental stability. Metal electrode 6 uses copper, silver and other metal electrodes or composite electrodes to ensure conductivity and flexibility. Encapsulation layer 7 can be composed of inorganic materials such as silicon oxide, aluminum oxide and silicon nitride, and POE or silicone and water-blocking film.

[0028] As shown in the figure, Figure 2 , 3As shown, the portable solar sunshade provided by the embodiment comprises a main rod 10, a handle 20 arranged at the bottom of the main rod 10, a foldable framework 30 arranged at the top of the main rod 10, and a sunshade cloth 40 connected to the foldable framework 30. The upper surface of the sunshade cloth 40 is covered with a flexible perovskite solar photovoltaic film 41 for converting solar energy into electric energy. The top of the main rod 10 is further provided with a lighting lamp 11 surrounding the main rod 10. The handle 20 is provided with a dimmer knob 21. The handle 20 is embedded with a storage battery (not shown in the figure). The storage battery is electrically connected with the flexible perovskite solar photovoltaic film 41 and can store the converted electric energy. The lighting lamp 11 is electrically connected with the dimmer knob 21 and the storage battery and is powered by the storage battery for lighting.

[0029] Specifically, the main rod 10 is made of high-strength aluminum alloy or stainless steel and the like to ensure the overall stability of the sunshade. The main rod 10 is hollow inside and arranged with wires connecting the flexible perovskite solar photovoltaic film 41, the storage battery, the dimmer knob 21, and the lighting lamp 11 to ensure smooth transmission of electric energy.

[0030] The foldable framework 30 is made of light metal or high-strength plastic to support the sunshade cloth and maintain its shape. The foldable framework 30 mainly comprises ribs, joints, sliding sleeves, springs, switches, and the like. The ribs are the main supporting part of the framework and are made of multiple slender metal rods or plastic rods connected together through joints, which can be flexibly unfolded and folded. The sliding sleeves and springs are arranged at the joints. The sliding sleeves are used to guide the movement of the ribs to make the opening and closing of the sunshade more smooth. The springs can provide a certain elastic force for the ribs to ensure that the sunshade can maintain a stable shape after being unfolded and can be folded together when being folded. The switches are used to control the opening and closing of the sunshade. The foldable framework 30 in the embodiment adopts the existing conventional structure and will not be described in detail here.

[0031] The sunshade cloth 40 is made of durable and light materials such as nylon or polyester fiber to ensure stability under various weather conditions. The flexible perovskite solar photovoltaic film 41 is tightly adhered to the sunshade cloth 40 by an adhesive and completely covers the upper surface of the sunshade cloth 40, which is integrated with the sunshade cloth 40, has a good overall structure fusion, is more beautiful, and occupies a small space when being stored. The flexible perovskite solar photovoltaic film 41 is adhered to the curved surface of the sunshade cloth 40, which can expand the light energy absorption area, improve the solar energy conversion efficiency, realize efficient use of energy, and also enhance the sun protection performance of the sunshade and improve the comfort of the user.

Compared with the traditional incandescent bulb (luminous efficiency about 15 lm / W), the energy consumption of LED is reduced by 80%, the service life is up to 50,000 hours, and the maintenance cost is significantly reduced. The illuminating lamp 11 is arranged at the top of the main rod 10, when the user holds the handle 20, the illuminating lamp 11 is located at a high position above the user's head and is arranged around the main rod 10, which is less blocked by the human body, the light can be uniformly diffused to the surrounding, and the light source located above has less stimulation to the user's eyes, which improves the comfort and safety. The dimmer knob 21 on the handle 20 can control the opening and closing of the illuminating lamp 11 and adjust the brightness of the illuminating lamp 11, which meets the use needs in different brightness environments and has high flexibility. At night, although street lamps can provide certain illumination, the coverage range of street lamps is limited, and the illumination effect may be affected by weather, terrain and other factors, the illuminating lamp 11 can provide additional illumination, which ensures that the user can clearly see the surrounding environment in the area without street lamps or insufficient light, avoids the danger caused by poor vision, and ensures the safety of outdoor activities. At the same time, the illumination effect of the illuminating lamp 11 makes it easier for drivers driving vehicles in the distance to observe pedestrians, and can more clearly identify road lines, obstacles and traffic signs, thereby effectively reducing traffic accidents.

Further, the handle 20 is further provided with a mode switching button, which is used to switch the illuminating lamp 11 to a constant-on mode or a flashing mode. When the constant-on mode is used, the top surrounding type LED lamp can provide 360° uniform illumination, with a coverage radius of up to 5 meters, which ensures that there is no dark area in the activity area; when the flashing mode is used, for example, in an emergency (such as being in danger in the wild), the user can use the flashing mode (frequency 5 Hz) through the mode switching button to use as an SOS signal lamp, which improves the rescue recognition rate.

[0034] When the sunshade is used in the daytime, the sunlight is irradiated on the flexible perovskite solar photovoltaic film 41 on the surface of the umbrella cloth 40, the flexible perovskite solar photovoltaic film 41 collects solar energy and converts it into electric energy, and the generated electric energy is transmitted to the storage battery in the handle through the wire inside the main rod 10. When used at night, the light bulb 11 can be lit through the light adjusting knob 21 on the handle 20, and the storage battery supplies power to the light bulb 11, and further rotating the light adjusting knob 21 can adjust the light bulb 11 to the appropriate brightness. In the dark place, the constant light mode can be opened through the mode switching button to provide stable lighting; in the scene of crossing the road at night or traveling in rain and fog, etc., the flashing mode can also be opened to send a warning signal or attract attention, thereby improving the safety.

[0035] The above-mentioned embodiments are preferred cases of the present application, and are not used to limit the protection scope of the present application.
