Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Figure 1 A photovoltaic cell provided by an embodiment of the present invention is shown, comprising a back sheet 101, a photovoltaic cell 102, and a light-transmitting front sheet 103. The back sheet 101, the photovoltaic cell 102, and the light-transmitting front sheet 103 are bonded together by an adhesive film 104, wherein:

In this embodiment, a photovoltaic cell is combined with an alumina sheet, and this photovoltaic cell sheet serves as the blades of the Venetian blinds. This simplifies the manufacturing process, effectively reduces the weight of the blades, and ensures power generation.

[0039] Figure 2a and Figure 2b The photovoltaic shutter provided by the embodiment of the present invention comprises Figure 1 The photovoltaic cell 201, the wire 202 and the blind host 203 are shown, and the blind host 203 includes a battery and a processing component;

[0040] The photovoltaic cell 201 is provided with a through hole. One end of the wire 202 is fixed to the last photovoltaic cell. The other end of the wire passes through the through hole and is connected to the blind main unit 203. The photovoltaic cell 201 is connected to the blind main unit 203 via the wire 202.

[0041] The processing component is used to receive the electrical energy of the photovoltaic cell 201 and store it in the battery, and is also used to control the lifting and turning of the photovoltaic cell.

[0042] Specifically, the photovoltaic cell 201 converts light energy into electrical energy and transmits the electrical energy to the battery in the blinds host through a wire. The battery serves as the power supply for the entire photovoltaic blinds and supplies power to other electrical components. The processing component includes a micro motor and a switch. The micro motor is used to control the lifting and flipping of the photovoltaic cell 201. The switch is used to provide relevant switch options and provide relevant operations for the user. The through hole provided on the photovoltaic cell 201 has a strong magnetic material wrapped by a conductive material. The conductive material can be copper foil or the like. More specifically, the two ends of the photovoltaic cell are divided into the positive and negative poles of the photovoltaic cell. The conductive material of the through hole serves as the guide bar of the photovoltaic cell, which collects the electrical energy generated by the photovoltaic cell. After contacting the wire, the photovoltaic cells are connected in parallel and send the generated electrical energy to the battery through the wire.

[0043] Furthermore, the conductive wire 202 includes an inner core and a first outer sheath wrapping the inner core, the inner core includes an adsorption material, and the first outer sheath is made of a conductive material.

[0044] Furthermore, the conductive wire 202 further includes a second outer skin, which is made of an insulating material. The second outer skin is included at a non-contact point between the conductive wire and the photovoltaic cell 201 .

[0045] In a specific application, the adsorption material is a ferromagnetic material, and the first outer skin is a copper braided hose.

[0046] Furthermore, the blind host 203 also includes a mounting body 2031 connected at both ends, a fan 2032 and an air purification filter element. The mounting body 2031 is provided with an air inlet and an air outlet 2033. The air inlet is provided at both ends of the mounting body 2031, and the air outlet 2033 is provided around the mounting body 2031.

[0047] The battery and the processing component are placed in the installation body 2031, the fan 2032 is arranged at the air inlet of the installation body 2031, and the air purification filter is arranged at the rear end of the fan 2032 to filter the air inhaled by the fan 2032, and the filtered air is discharged from the air outlet 2033.

[0048] In the specific implementation process, the material of the air purification filter can be selected according to actual needs, such as photocatalyst, activated carbon, synthetic fiber, HEPA high-efficiency material, negative ion generator, or a composite type can be used, that is, multiple purification technologies and material media are used at the same time.

[0049] Furthermore, the blind host 203 also includes a lighting component 2034 and a communication component

[0050] The lighting component is connected to the battery and the processing component, and is used to turn on or off lighting under the control of the processing component.

[0051] The communication component is connected to the processing component and is used to exchange information with an external system through a communication protocol.

[0052] Specifically, the lighting assembly can be implemented by LED lamps or LED light strips. In actual applications, the LED lamps can be set around the air inlets at both ends of the mounting body, or the LED light strips can be set on the mounting body. The processing component uses a built-in clock module to achieve timed on and off of the lighting assembly. At the same time, the user can also turn the lighting assembly on or off by using a switch. The communication component includes a WiFi module, an infrared module, a 4G module, or a 5G module. The communication component is connected to the processing component and exchanges information with the external system through a wireless transmission protocol. It receives control instructions or setting instructions sent by the external system, and sends the control instructions or setting instructions to the processing component so that the processing component performs corresponding operations according to the control instructions or setting instructions.

[0053] The photovoltaic blinds provided in an embodiment of the present invention also include an adjustment component, a mosquito repellent component or a disinfection component. The adjustment component is used to automatically adjust the opening and closing angle of the photovoltaic cell according to sunlight, the mosquito repellent component is used to repel mosquitoes using ultrasound, and the disinfection component is used to disinfect using an ultraviolet germicidal lamp.

[0054] Take the lighting component as a colored night light and the photovoltaic cell as a CIGS cell as an example, combined with Figures 1 to 3 The embodiments of the present invention are further explained:

[0055] Figure 1 A CIGS cell is shown. Because CIGS cells are sensitive to water vapor, this CIGS cell uses an alumina sheet as the backsheet 101 for the CIGS cell package. Adhesive film 104, CIGS cells 102, adhesive film 104, and a transparent front sheet 103 are sequentially applied. Backsheet 101 can also be made of other high-barrier materials with other insulating properties. The transparent front sheet 103 can have a highly weather-resistant outer layer and a high-barrier inner layer. The surface of the CIGS cell can be embossed with various patterns as needed, and the high-barrier material used to make the backsheet 101 can be customized to suit customer needs.

[0056] Figure 2a and Figure 2bThe main structure of the photovoltaic blinds provided by an embodiment of the present invention is shown. The photovoltaic blinds are mainly composed of CIGS cells 201 and a blinds host 203. Each CIGS cell 201 is connected to the blinds host 203 through a wire 202 with a built-in ferromagnetic material (such as iron, cobalt, nickel, etc.). The bottom of the wire 202 is fixed on the last CIGS cell 201, and the rest of the wire 202 passes through a strong magnetic material wrapped by a conductive material (such as copper foil) on the CIGS cell 201. The two ends of the CIGS cell 201 are divided into the positive and negative poles of the CIGS cell. When the blinds stop pulling, the strong magnetic material wrapped with the conductive material attracts the wire 201 to form a loop, and the wire 201 transmits the collected current to the blinds host 203. The blinds host 203 has a built-in high-capacity battery, a fan 2032 and an air purification filter. Air is drawn in by fans 2032 installed at both ends of the blind main unit 203, passes through an air purification filter, and is discharged through outlets 2033. A micromotor is installed within the blind main unit 201 to control the raising and lowering of the blind and the rotation of the CIGS cells. Colored night lights 2034 are installed at both ends of the blind main unit to provide nighttime illumination. The blind main unit also has a built-in communication component, including an infrared receiver module and a WiFi module. This communication component exchanges information with external systems via wireless communication protocols, enabling the blind main unit 203 to be controlled by external systems such as remote controls or smart devices.

[0057] Figure 3 The internal structure of the conductor 202 is shown. The conductor 202 is mainly composed of an inner core 301 composed of a ferromagnetic material and a first outer sheath 302 composed of a copper braided hose 3. Because the back packaging material of the CIGS cell is an aluminum oxide sheet and the front is a polymer plastic, and the CIGS cells are connected in parallel with each other, and the positive and negative poles are far apart, there is no need to consider the insulation of the conductor 202. In addition, the safe voltage provided by the CIGS cell will not cause harm to the human body. In the specific process, when it is necessary to increase the voltage or current of the CIGS cell, a second outer sheath can be applied to the non-contact point between the CIGS cell 201 and the conductor 202. This second outer sheath is insulated. The insulation treatment method can be to apply an insulating skin, an insulating film, or spray an insulating paint on the non-contact point of the conductor 202.

[0058] This embodiment of the present invention solves the packaging problem of flexible CIGS cells in Venetian blinds. Using an integrated packaging process, the aluminum blades of traditional Venetian blinds serve as the backplane for the photovoltaic cells. A film, photovoltaic cells, film, and a transparent front plate are then laminated to create an integrated package. Because the stainless steel substrate used for CIGS cells is relatively thin, an ultra-thin flexible package can be used. The encapsulated CIGS cells not only offer long-term reliability but also retain the thinness and bendability of traditional Venetian blinds.

[0059] The embodiment of the present invention further solves the problem of current collection for each photovoltaic cell in a photovoltaic blind by utilizing a built-in ferromagnetic wire to easily collect current when the photovoltaic cell is in different states through magnetic attraction.

[0060] The present invention also addresses the problem of traditional solar blinds using only the electricity generated by solar cells to open and close the blades to adjust light. The present invention can purify the air in the room through a fan + air purification filter, and realize a night light function at night through the lighting component. Furthermore, the communication component, including a Wi-Fi module or an infrared module, can be used to adjust the photovoltaic blinds through remote controls, mobile phones, and other smart devices. The ultra-large capacity lithium battery built into the present invention serves as a power source, allowing the photovoltaic blinds to continue to function as night lights and air purifiers at night.
