Description

Technical Field

[0001] The present invention relates to the field of intelligent wearable technology, and in particular to an electronic communication cap. Background Art

[0002] At present, when using a mobile phone, it is inevitable to hold the phone in the hand and look down at the limited display screen, which leads to cervical spine problems caused by "phone-down tribe". The inevitable use of mobile phones when walking or strolling also brings safety hazards, such as collision with others, collision with pedestrian obstacles such as road signs and trees, and even the risk of tripping; in addition, holding the mobile phone hinders the freedom of movement of the hands. In a word, the popularity and use of smart phones has not yet liberated modern people's "hands and cervical spine".

[0003] In order to improve the shortcomings of the above-mentioned mobile phones, one of the existing methods is to use wired or wireless Bluetooth-connected headphones to facilitate mobile phone calls, temporarily freeing one or both hands for voice interaction. This has the advantages of being simple and convenient, but the disadvantage is that it is impossible to view the increasingly informative pictures, texts, emails, short videos, movies and other content obtained through mobile phone communications. In order to watch pictures, videos and movies, virtual reality goggles VR (Virtual reality) have been launched on the market. Their characteristics are immersive viewing, especially 3D viewing, which achieves unprecedented audio-visual effects and seems to be a virtual effect as if you are there in person. However, the eye fatigue effect caused by them and the inability to observe the surrounding environment at the same time limit their use as a communication tool. Recently, augmented reality glasses AR (Augment reality) have also been launched, which aim to superimpose digital information on the user's reality through augmented reality technology. Users can interact with the device through voice commands, gestures or head movements. The transparent display used can display notifications, text messages, emails, short videos and movies in real time. The AR glasses support voice commands to reduce the trouble of manual operation, which is very convenient for users who operate other tools with both hands, and help workers on complex assembly lines to use interactive guidance work to improve work accuracy and work efficiency. However, their display capabilities are relatively limited, mainly for information display, and cannot provide complex 3D images and holographic images. The battery life is also limited to 2 hours. The recently launched MR (mixed Reality) is a fusion of hybrid augmented reality (AR) and virtual reality (VR) technologies. It has 3D precision display and is mainly used in medical, education, entertainment and manufacturing fields. Its high power consumption and eye fatigue caused by wearing and watching, coupled with the discomfort of the ears due to the weight, and its battery life of only 2 hours, have hindered its possibility of becoming a new generation of mass communication device.

Its appearance is composed of flexible thin-film solar cells 10; the inside of the electronic communication hat adopts multi-region sub-solar cell components in series and parallel circuits and intelligent management; the inside of the electronic communication hat can be optionally lined with natural or synthetic fiber fabrics to increase comfort, beauty or durability. The internal and external designs meet the requirements of soft wear, breathability, adjustable size and fastening accessories according to the head shape, easy to clean and firm and durable; the flexible thin-film solar cell 10 of the electronic communication hat has an output wiring port, and the flexible thin-film solar cell 10 has a photoelectric energy conversion efficiency PCE greater than 22% under the standard AM 1.5G spectrum illumination.

[0045] The electronic communication cap of the present invention belongs to a wearable electronic device. The cap body must meet the requirements of lightness, thinness and flexibility suitable for the human body while meeting the functional requirements and durability, and must also ensure sufficient photovoltaic power generation under the limited surface area of ​​the cap. For example, in a moderate sunlight, it can generate enough photovoltaic power to support a mobile phone, a pair of display glasses with sufficient brightness (maximum brightness 1000-5000 nits) with camera function, and two sufficiently powerful speakers and microphones (maximum power 5 watts) for simultaneous use.

[0046] The flexible thin-film solar cell of the electronic communication cap is divided into the cap top, cap body and cap brim, and each part is subdivided into at least 2-8 areas, which is convenient for the zoning management of current when the light is uneven; Figure 1-Figure 8 In the electronic communication hat, the electronic communication hat can be a bowler hat, and its size and decoration can be suitable for men, women, old and young, and it is generally composed of a dome, a cylindrical hat body and a brim around it. The outer surface area of ​​a bowler hat with a dome diameter of 20cm, a hat body height of 15cm and a brim width of 10cm is about 1570cm 2 Considering that the sunlight intensity on a cloudy day is generally 2500 lux, or 300W / m 2, and the power consumption of a general mobile phone when in use is 5 watts, and the surface of the hat receives about 50% of the light, so the energy conversion efficiency of the photovoltaic module is required to be greater than 22%; a flexible thin-film solar cell round block with a suitable diameter is selected as the hat top 11; a rectangular flexible thin-film solar cell is surrounded by the hat body 12; an annular flexible thin-film solar cell is used as the brim 13, the brim 13, the hat body 12, and the hat top 11 are all flexible thin-film solar cells, and the appearance of the electronic communication hat thus formed is a photovoltaic device covering the entire area, which can improve the utilization rate of light and the power of photovoltaic cells to achieve the endurance of driving communication equipment.

[0047] for Figure 1-Figure 8 The arc-shaped hat in the embodiment achieves the reasonable lighting area, overall voltage and current requirements of the electronic communication hat by series and parallel connection; the shape of the electronic communication hat can be cut according to the design of the hat by the flexible thin-film solar cell; the brim 13 of the electronic communication hat is divided into three third areas, namely A1, A2 and A3, and the areas of A1, A2 and A3 are the same; the hat body 12 is divided into three second areas, namely B1, B2 and B3, and the areas of B1, B2 and B3 are the same; the hat top 11 is divided into three first areas, namely C1, C2 and C3, and the areas of C1, C2 and C3 are the same.

[0048] In the embodiment of the present invention, the electronic communication hat is divided into multiple areas according to the brim 13, the hat body 12, and the hat top 11 for series-parallel connection of solar cells. The electronic communication hat can be divided into the hat top, the hat body and the brim. The hat top can include three first areas, each of which is a sub-solar cell assembly, and the three sub-solar cell assemblies are connected through a parallel circuit, and each sub-solar cell assembly is composed of six sub-solar cells connected in series; the hat body can include three second areas, each of which is a sub-solar cell assembly, and the three sub-solar cell assemblies are connected through a parallel circuit, and each sub-solar cell assembly is composed of six sub-solar cells connected in series; the hat top can include three third areas, each of which is a sub-solar cell assembly, and the three sub-solar cell assemblies are connected through a parallel circuit, and each sub-solar cell assembly is composed of six sub-solar cells connected in series; then each area is connected to the output port or the power supply port through a parallel circuit to work; according to the principle of equal division, a sub-solar cell can be divided every 20 degrees in the brim 13, the hat body 12 and the hat top 11, and 6 sub-solar cells, that is, every 120-degree arc, form a sub-solar cell assembly, and each sub-solar cell assembly is composed of 6 sub-solar cells connected in series. The flexible thin film sub-solar cell is a single-cell solar cell or a multi-cell stacked solar cell. Here, a single-cell solar cell is defined as each sub-cell containing one pn semiconductor node, and a multi-cell stacked solar cell is defined as each sub-cell containing multiple stacked pn semiconductor nodes.

[0049] For example, the embodiment of the present invention uses a flexible perovskite solar cell with a PCE of 23% and a power per unit area of ​​230 W / m2 as raw materials under standard illumination spectrum conditions, and the following steps are performed to make a photovoltaic cap:

[0050] Making the top of the hat: A circular soft photovoltaic sheet with a diameter of 20.3 cm is obtained as the dome. According to the principle of equal division, a sub-solar cell is divided every 20 degrees on the circular top of the hat. Every 6 sub-solar cells are connected in series to form a sub-solar cell module, and every 120-degree arc forms a sub-solar cell module; after deducting the area loss caused by the gluing of the final product, the effective area is S1=πr 2 =3.14x102=314cm 2 .

[0051] Making the hat body: The prefabricated hat body photovoltaic panel is a rectangle with a length of L = 2πr = 62.8cm and a height of H = 19.5cm. Every 20 degrees is divided into a sub-solar cell, and every 6 sub-solar cells are connected in series to form a sub-solar cell module, or in other words, every 120 degrees of arc forms a sub-solar cell module; the rectangle surrounds the hat body, and the edges are fixed with glue and sewn for reinforcement; its effective area S2 = 2πrH = 2x3.14x19 = 1193cm 2 .

[0052] Manufacturing the brim: The prefabricated brim forms a ring with an outer diameter of 2R = 38 cm and an inner diameter of 2r = 20 cm. A sub-solar cell is divided every 20 degrees, and every 6 sub-solar cells are connected in series to form a sub-solar cell module, or a sub-solar cell module is formed every 120 degrees of arc; its effective area is S3 = πR2-πr2 = 819 cm 2 .

[0053] Assembling the electronic communication hat: Use bisphenol A glue to glue the disc on the top of the hat and the cylinder formed by the hat body, connect the top of the hat, the hat body and the brim, and finally use fishing line to sew to strengthen the firmness.

[0054] Connect the leads to the output port: Connect the reserved male and female matching wires of the top, body and brim of the hat into the body of the hat, and export the positive and negative poles of the flexible thin-film solar cell to the USB-Type C connector.

[0055] Install a flexible photovoltaic cap lining: use breathable, firm and head-fitting natural tweed, reinforced natural fiber fabric or synthetic fiber fabric as the lining, and use universal glue to bond it to increase the firmness and wearing comfort of the electronic communication cap; an adjustable buckling inner ring can be installed in the lining to adjust the head shape of different people.

[0056] Molding: Use steam hot pressing technology to place the hat into the molding mold, and control the mold to shape at 80 degrees Celsius to ensure that the shape meets the design requirements.

[0057] The total area of ​​the hat thus prepared is: 2326cm 2 , the theoretical maximum power = 0.2326x230 = 53W (according to 1000W / m2 illumination); the actual test at noon vertical irradiation area is: 1133.5cm2, maximum power = 0.1133x230 = 26W (according to 1000W / m2 illumination), open circuit voltage Voc = 6.5V, short circuit current Isc = 4.0A; in cloudy weather, the diffuse illumination is halved to 500W / m 2 The maximum power under test is: 115·(0.2326 / 2)=13W, Voc=6.5V, Isc=2.0A. In the comparison case, the hat of the same size uses the best commercial monocrystalline silicon as the solar cell. Although its energy conversion efficiency can reach PCE=23%, it can only use rectangular and circular blocks because it cannot be made into a flexible photovoltaic panel. The effective area of ​​the hat photovoltaic panel is discounted by 80%. The actual test at noon is vertically illuminated: 80%x1133.5cm2, maximum power = 0.8x0.1133x230 = 20.8W (under 1000W / m2 illumination), open circuit voltage Voc = 5.2V, short circuit current Isc = 2.08A; in cloudy weather, the diffuse illumination is halved to 500W / m 2 The maximum power is tested below: Power = 5.2W, Voc = 5.2V, Isc = 1.0A.

[0058] In another embodiment, the outer diameter of the brim 13 is R=19 cm, the outer radius of the cap body 12 is r=10 cm and the height is H=19 cm. The total area of ​​the brim 13 is A=π(R 2 -r 2 )=3.14x(192-102)=819cm 2 The area of ​​the three first regions is A1 = A2 = A3 = 273 cm 2 The total area of ​​the cap body 12 is B = 2πrH = 2x3.14x10x19 = 1193cm 2 The area of ​​the three second regions is B1 = B2 = B3 = 397 cm 2 ; The total area of ​​the top of the hat 11 is C = πr 2 =3.14x102=314cm2, the area of ​​the three third regions C1=C2=C3=104cm 2 ;exist Figure 1-Figure 8 In the flexible thin-film solar cell, the maximum power voltage Vmp of each sub-solar cell is 1V, and the maximum power current density Jmp is 24mA / cm 2Under ideal conditions, the output voltage of the brim 13, the hat body 12 and the hat top 11 is V13=V12=V11=6x1V=6V, I13=IA1+IA2+IA3=24x(A1+A2+A3)=6552+6552+6552=19656mA; I12=IB1+IB2+IB3=24x(B1+B2+B3)=9528+9528+9528=28584mA; I11=IC1+IC2+IC3=24x(C1+C2+C3)=2496+2496+2496=7488mA; the brim 13, the hat body 12 and the hat top 11 form a USB type C output end of the flexible thin film solar cell through a parallel circuit.

[0059] According to the flexible perovskite solar cell used in the present invention, the energy conversion efficiency under standard illumination spectrum conditions is currently the best in the industry. The PCE of a single-node solar cell is 26%, and the power per unit area is 260W / m2. As raw materials, the total top hat area is 2577cm2, and the theoretical maximum power = 0.2577x260 = 67W (according to 1000W / m 2 Illuminance); Diffuse illuminance in cloudy or overcast weather is 250W / m 2 The maximum power measured is 8W, Voc=10V, Isc=0.8A. It can fully meet the energy requirements of mobile phones and display glasses.

[0060] Under indoor lighting, the lighting in laboratories and operating rooms is 1000-5000 lux, and in other indoor places such as shopping malls, the illumination is usually 500-1000 lux. Under indoor LED lighting (1000lux, 4000K, 10W / m2), its maximum power is theoretically: 0.26x0.2577m2x10W / m2=0.67W (according to the simulated solar spectrum). The actual measured peak voltage of the photovoltaic cap is V=10V, the current density is 150mA, and the power is: 10x0.15=1.1W, indicating that the perovskite thin film photovoltaic has the performance of weak light power generation and super absorption of LED light spectrum. It can meet the power consumption of general voice communication of mobile phones. Comparative example: A hat of the same size, using the best commercial monocrystalline silicon as a photovoltaic module, has an energy conversion efficiency of PCE = 23%. However, since it cannot be made into a flexible photovoltaic panel and can only use rectangular and circular blocks, the effective area of ​​the hat photovoltaic panel is reduced by 80%. The actual test at noon vertical irradiation area is: 80% x 0.2577 x 260 = 53.6W / cm 2 , the maximum power measured under diffuse illumination of 250W / m2 in cloudy or overcast weather is: 5W, Voc=5.2V, Isc=0.96A. Under indoor LED lighting (1000lux, 4000K, 10W / m 2) illumination, its maximum power is theoretically: 0.23x0.2577m2x10W / m2=0.59W (according to the simulated solar spectrum). The actual measured peak voltage of the photovoltaic cap is V=10V, the current density is 20mA, and the power is: 10x0.02=0.2W; it cannot meet the effective power supply function.

[0061] Taking into account that the photovoltaic currents generated in different areas of the electronic communication helmet are different in different scenarios such as slanting sunlight in the morning and evening, overhead sunlight at noon, and cloudy or scattered light indoors, the user is likely to move all the time in the sunlight, and the sunlight area and the dark area change at any time. When the photovoltaic current generated at a certain moment is significantly lower than the required value, the dark area (non-power generation area) may consume the current generated by the sunlight area (power generation area), and even suffer damage from reverse current in severe cases. The embodiment of the present invention can prevent the reverse current from being conducted by providing an anti-backflow device, thereby ensuring the stability and effectiveness of the electronic communication helmet.

[0062] The electronic communication hat provided by the technical solution of the embodiment of the present invention includes: a flexible thin-film solar cell 10 includes a hat top 11, a hat body 12 and a hat brim 13, all of which are flexible thin-film solar cells, the flexible thin-film solar cell of the hat top 11 is a first solar cell component 01, the flexible thin-film solar cell of the hat body 12 is a second solar cell component 02, and the flexible thin-film solar cell of the hat brim 13 is a third solar cell component 03; the first solar cell component 01, the second solar cell component 02 and the third solar cell component 03 are connected through a parallel circuit; the flexible thin-film solar cell of the hat top 11 includes a plurality of first regions of the same area, each of which is a sub-solar cell component, and the plurality of sub-solar cells of the hat top 11 are connected to each other through a parallel circuit.

The brim 13, the hat body 12, and the top 11 of the electronic communication hat in the technical solution of the embodiment of the present invention are all flexible thin-film solar cells, which can improve the utilization rate of light and the battery life; by setting the anti-backflow device, the reverse current of each sub-solar cell component can be prevented from being conducted, thereby ensuring the stability of the electronic communication hat.

[0063] Optionally, multiple anti-reverse diodes, preferably blocking diodes, can achieve forward conduction and reverse cutoff; the output end of each sub-solar cell module is connected in series with an anti-reverse diode; the output end of the first solar cell module is connected in series with an anti-reverse diode, the output end of the second solar cell module is connected in series with an anti-reverse diode, and the output end of the third solar cell module is connected in series with an anti-reverse diode.

[0064] Among them, the output end of each sub-solar cell module is connected in series with an anti-reverse diode, which can prevent reverse current conduction of each sub-solar cell module; the output end of the first solar cell module is connected in series with an anti-reverse diode, the output end of the second solar cell module is connected in series with an anti-reverse diode, and the output end of the third solar cell module is connected in series with an anti-reverse diode, which can prevent the reverse current conduction of the first solar cell module, the second solar cell module and the third solar cell module, thereby preventing reverse current conduction of each sub-solar cell module, thereby ensuring the stability of the electronic communication hat.

[0065] Optional, Fig. 9 is a structural diagram of another electronic communication cap provided by an embodiment of the present invention, referring to Fig. 9 The electronic communication cap also includes: a control device 40, which is located on the inner side of the cap body and is electrically connected to the flexible thin-film solar cell 10; the anti-backflow device includes a plurality of switches, each sub-solar cell assembly is connected in series with a switch; the control device 40 is used to send a first control instruction to the flexible thin-film solar cell 10, and the flexible thin-film solar cell 10 controls the opening or closing of the corresponding sub-solar cell assembly in response to the first control instruction. The switch can have different options, one is a micro relay, and the first choice is a DC solid-state relay DC-SSR (Solid state relay).

[0066] in, Fig. 9 The middle hat body also includes the wiring of the sub-solar cell modules in different areas, as well as a wearable lining and an output interface of the flexible thin-film solar cell; the control device 40 can be a microprocessor, and the microprocessor can include any one of a power intelligent controller BMD, a programmable logic controller and a driver chip (PLC); the control device 40 also includes a management driver chip module to automatically manage the charging and discharging of the flexible thin-film solar cell; turn on the mobile phone, display glasses, manage the charging and discharging of the flexible thin-film solar cell and select audio, video, and function menus.

[0067] When designing an electronic communication cap, since the user is likely to move all the time in the sun, the sun area and the dark area change at any time. When the photocurrent generated at a certain moment is significantly lower than the required value, the system should automatically close the circuit to prevent the dark area (non-power generation area) from consuming the current generated in the sun area (power generation area), and even encounter reverse current damage in severe cases. One way is to use a simple two-pipe in each sub-solar cell module series circuit to prevent reverse current conduction. Another way is to use a programmable logic controller or a driver chip (PLC) in the cap body, configure an input and output module in the PLC, connect the switches and control signals of each area, and automatically control the switches of different areas according to the preset logic and real-time data. When the embodiment of the present invention uses a driver chip, an input and output module can be configured in the driver chip, multiple switches of the anti-backflow device can be connected, and multiple control signals can be transmitted to the anti-backflow device. According to the preset logic and real-time data, the switches at different positions are automatically controlled, thereby avoiding the damage of reverse current; or, when using a power intelligent controller BMD, it is connected to the central monitoring system of the microcontroller, and the built-in control chip in the microprocessor is coordinated to combine the prefabricated algorithm with the voltage-current automatic control. The control chip automatically controls the switches of different areas according to preset logic or real-time data. For example, in the midday sun, the multiple first areas of the top of the hat and the multiple third areas of the brim generate mainstream photovoltaic electricity, while the multiple second areas of the hat body have no photovoltaic effect; when the sun shines obliquely, the light-facing side of the electronic communication hat includes the top of the hat, the hat body and part of the brim, and the light-facing side generates mainstream photovoltaic electricity, which the control device recognizes and turns on the switch of the corresponding sub-solar cell module, while less photovoltaic current is generated on the backlight side, and the control device recognizes and turns off the switch of the corresponding sub-solar cell module, thereby preventing each sub-solar cell module from becoming a resistive load and consuming power, or even being damaged by reverse current.

[0068] The top, body and brim of the electronic communication cap generate different photovoltaic currents in different areas under different scenarios such as morning and evening sun, noon top exposure, and cloudy or indoor scattered light. Especially in the light and dark areas, when the photovoltaic current is small, it is necessary to automatically shut down its function, otherwise the current in the area with large photovoltaic current will be consumed due to the series constant current effect. By dividing the top, body and brim of the cap into multiple areas, and performing zoned conduction and disconnection control on multiple areas, the overall efficiency can be improved by optimizing the flow of power and improving its stability during the use of the electronic communication cap; and the zone control can quickly isolate the fault area when a fault occurs to prevent the fault from spreading to the entire device. Therefore, during the use of the electronic communication cap, especially when it is moved to a different environment, the stability of the entire system can be improved by performing zoned conduction and disconnection control on multiple areas.

[0069] The zoning control described in the present invention can divide the top, body and brim of the electronic communication hat into multiple areas, each area can be independently controlled and optimized, and the zoning control design can improve the overall flexibility and scalability of the equipment, so that it can cope with different operating conditions and changes in demand; the zoning on and off control significantly improves the overall efficiency of the flexible thin-film solar cells in the equipment by optimizing power flow, improving equipment stability, optimizing energy utilization and enhancing equipment flexibility.

[0070] Optionally, the electronic communication hat also includes: a driving device, whose circuit is usually composed of one or more power metal oxide semiconductor field effect transistors (MOSFET). After the driving circuit receives the control signal, the MOSFET is turned on, allowing the current in the load circuit to pass. The driving device is located on the inner side of the brim or the top of the hat; the flexible thin film solar cell 10 is used to power the driving device; the control device 40 is also used to send a second control instruction to the driving device, and the driving device responds to the second control instruction to perform a corresponding operation. Obviously, the control device and the driving device can be combined through an integrated circuit chip to become a so-called microprocessor ( Fig.10 shown).

[0071] in, Fig.10 The microprocessor in the device is responsible for identifying, contacting, and controlling the communication devices used with the electronic communication cap, including Fig. 9 The display glasses 60, mobile phone 50, and speaker 30 are shown; the position of the mobile phone 50 needs to be provided with a mobile phone insertion pocket for fixing the mobile phone, and the mobile phone is used by wired or wireless connection; two display glasses 60 can be provided, corresponding to the left eye and the right eye respectively, and the display glasses 60 are fixed in the communication hat brim by a rotating shaft, and they are all flip-up display glasses. A lining 70 is also provided inside the electronic communication hat, and natural or synthetic fiber fabrics can be used as the lining to increase comfort, beauty or durability, so that it is more comfortable to wear, and it can also protect the control device 40 or microprocessor provided in the hat body. The control device can drive the driving device separately, and can control any driving device according to the needs, and the control instructions include but are not limited to opening, closing, displaying pages, switching audio, etc.

[0072] Exemplarily, the driving device (microprocessor) service in the embodiment of the present invention includes a mobile phone, and at least one insertable pocket can be installed on the inner rear of the brim or the inner side of the top of the hat, at least one personal smart phone can be placed and equipped with the charging and discharging, audio and video interface of the mobile phone. At present, most smart phones have a length x width x thickness of 75x160x9mm, and a universal USB type-C multi-function interface can be used to meet the connection and transmission of current and audio and video. The USB Type-C output interface is not only limited to charging and discharging and data transmission functions, but also includes functions such as video output, audio output, and a multi-function docking station; the multi-function docking station includes a display, a keyboard, a storage device, artificial intelligence, etc.; when the mobile phone is connected to the electronic communication hat in the present invention through USB Type-C, the electronic communication hat is controlled by the control device 40, and the functions of the mobile phone can be transferred to the electronic communication hat, so that all normal telephone functions can be used.

[0073] Current smartphones consume different amounts of power and energy depending on the usage scenario. For example, in standby mode, only 0.1-0.5 watts is needed to maintain network connection; 2-4 watts is needed when browsing social media and using the screen and light processor; 4-8 watts is needed when watching videos and browsing web pages and using the screen and image processor GPU load; when playing high frame rate games, recording videos, and navigating, the screen, CPU, GPU, and GPS are needed, and 6-10 watts are needed overall. Obviously, reducing the screen of a mobile phone or not using the screen of a mobile phone without affecting the function is a way to save power consumption; the electronic communication cap of the present invention is compatible with existing smart phones on the one hand, and the technical method adopted is to design a mobile phone in the electronic communication cap to insert the pocket to place the mobile phone, which can be controlled by a data cable or wireless connection through the control device 40 in the electronic communication cap, and the display screen of the mobile phone is transferred to the display glasses 60. The audio of the mobile phone is transferred to the speaker and microphone of the electronic communication hat; since the distance between the display glasses and the eyes is shortened, the distance between the speaker and the microphone and the user's ears and mouth is shortened, which can achieve better audio and display effects, better sound quality enjoyment, and better sound transmission; in addition, due to the smaller size of the display glasses and the shortened distance, display power consumption is also saved.

[0074] Exemplarily, the driving device service in the embodiment of the present invention includes display glasses, and the display glasses in the embodiment of the present invention include 1-2 near-eye display glasses. Near-eye display technology (NED) is a technology that presents images or information directly in front of the user's eyes, and is widely used in augmented reality (AR), virtual reality (VR) and mixed reality (MR) devices. At present, near-eye displays usually use micro displays the size of a fingernail, such as light-emitting diode (LED) displays, organic light-emitting diode (OLED) displays, liquid crystal displays (LCD) or liquid crystal on silicon (LCoS), which have high resolution (4K) and high refresh rate to ensure clear and smooth images. In addition, the micro display projects the image onto the user's retina or glasses lens through an optical system to form a virtual image; the optical system is used to magnify the image of the display and project it into the user's field of view through components such as lenses or waveguides. This type of optical projection has the advantage of power saving, but the design needs to be precise to ensure the clarity and field of view of the image. The embodiment of the present invention can be any kind of near-eye display, which can be set according to actual needs. Taking into account firmness, quality, and ease of use, the present invention preferably uses energy-saving and power-saving OLED or LED micro-display glasses, which can provide an immersive visual experience and even a semi-transparent display, making the user feel as if they are in a virtual environment or an augmented reality scene.

[0075] 1-2 display glasses are placed at the position corresponding to the glasses inside the brim of the hat. The user can choose binocular display, monocular display, or no display mode through mechanical flipping. In binocular display, different images are displayed through the left and right eyes attached to the video source respectively, realizing stereoscopic vision and three-dimensional effects, augmented reality and virtual reality applications. In monocular display, while one eye observes the environment, the other eye can watch the display content, including images, videos, text, etc., which can achieve an excellent enhancement of virtuality and reality. In addition, switching between the left and right eyes can also relieve eye fatigue.

[0076] Near-eye display usually integrates a variety of sensors, such as gyroscopes, accelerometers and eye tracking sensors, to track the user's head movement and eye movement, thereby achieving a more natural interactive experience and autofocus function. A micro camera can be installed on the edge of the micro display glasses to ensure the photography and video functions. At the same time, the depth sensor can be used to recognize the user's gestures, realize a more intuitive gesture interaction method, and control the switch of video and photography. Near-eye display has been applied to AR, VR, and XR glasses, and its weight ranges from 20 grams to 100 grams. Speakers can be installed on the edge of the micro display glasses to implement voice control, and the wearer can hear sound or music. The display glasses in the embodiment of the present invention are integrated on the electronic communication hat brim, which can avoid the discomfort of the eye sockets, nose bridge, and cheeks that are easy to produce when wearable glasses need to bear weight, and have the advantage of significantly improving the existing AR, VR, and XR glasses. In addition, the flexible thin-film solar cell hat body 10 of the present invention has a photovoltaic power generation function, and a charging and discharging device can also be set on the hat body. Combined with the mobile phone itself has its own battery, the advantages brought by providing power from three aspects fully surpass the battery life problems that existed in VR, AR, and XR in the past. It can greatly reduce display page delays, increase refresh rates, reduce dizziness and improve user experience, thereby providing high-quality visual experience and natural interaction methods for near-eye display technology, and playing an increasingly important role for near-eye display technology in virtual reality, augmented reality, and mixed reality.

[0077] Optional, reference Fig. 9 The electronic communication cap also includes: a charging and discharging device 20, which is located on the inner side of the cap body; the charging and discharging device 20 is used to store the electric energy converted by the flexible thin film solar cell 10, or the charging and discharging device 20 directly supplies power to the driving device.

[0078] The charging and discharging device 20 can be a storage battery or a lithium-ion secondary battery. When the flexible thin-film solar cell 10 cannot supply power in the dark area, it can provide power for the driving device; and when the sun is shining, the charging and discharging device 20 can be charged by the flexible thin-film solar cell 10. If the driving device is a mobile phone, its operation and control firstly use the photovoltaic power generation of the flexible thin-film solar cell 10, and when the power generation is insufficient, the charging and discharging device 20 is used secondly, and finally the mobile phone battery is used to ensure the excellent power endurance of the overall electronic communication hat. If the charging and discharging device 20 is a lithium-ion secondary battery, its suitable capacity is 5000-20000mAh, and it can be charged in outdoor sunny weather, and the charging degree is generally set between 0.2-1.0C (C is the battery capacity); and when the indoor light intensity is weak, the power consumption of mobile phones, display screens, etc. is continued; under extreme conditions, such as at night, the flexible thin-film solar cells 10 are all turned off and the charging and discharging device 20 is used; when there is sufficient sunlight outdoors, the photovoltaic current generated by the flexible thin-film solar cells 10 in the electronic communication helmet is greater than the current or electrical energy used. At this time, the excess photovoltaic electricity automatically charges the device 20 until it is fully charged.

[0079] Optionally, the driving device in the microprocessor includes at least one of display glasses, a mobile phone, a speaker, a microphone and a multi-talkie.

[0080] Among them, at least one earphone speaker and one microphone can be optionally installed on the left and right sides of the inner side of the brim of the electronic communication hat, and the power of the speaker and the microphone are not less than 5 watts; an insert pocket can be installed on the inner rear of the brim or the inner top of the hat to facilitate the placement of a personal smartphone, and is equipped with a power supply and Bluetooth headset interconnection function; the hat body contains a charging and discharging device, preferably a lithium-ion secondary battery, whose charging and discharging capacity is greater than or equal to 1Ah, preferably 2000-10000mAh, and is equipped with a power management charging and discharging function; the inner side of the front brim of the hat can optionally contain 1-2 flip-up micro-display glasses, which can be flipped down and flipped up It can achieve close-eye viewing with or without providing video, text, and pictures, and can realize alternating use of the left and right eyes or rest mode; the pixels of the micro-display glasses are at least 4K resolution, and their brightness is not less than 2000 nits. They can optionally carry video, photography, and sound speaker functions, and are equipped with a driver chip for near-eye display care; the cap body can optionally include a microprocessor to manage the driver chip and control device, automated communication and collaborative walkie-talkie functions, mobile phones, display glasses, flexible thin-film solar cell charging and discharging, and audio, video, and function menu selection, and its computing and image processing capabilities support at least 4K display resolution and 60fps high frame rate.

[0081] Exemplarily, the driving device in the embodiment of the present invention includes a walkie-talkie. Both walkie-talkies and mobile phones are devices that transmit voice through wireless signals. Both walkie-talkies and mobile phones use microphones to convert voice signals into electrical signals (audio signals), but walkie-talkies usually use VHF or UHF frequency bands, while mobile phones use cellular network frequency bands (such as GSM, CDMA, 4G, 5G, etc.). Obviously, the signal processing of walkie-talkies is relatively simple, and its functions can be realized as long as analog or simple digital modulation is performed; walkie-talkies adopt a simplex communication mode and implement point-to-point or point-to-multipoint communication. Its communication distance is limited (usually within a few kilometers) and the power consumption is relatively large, usually 1-5 watts; the characteristic of walkie-talkie communication is that it does not require base station support and is directly transmitted through radio waves. Therefore, in some special occasions, especially in mountainous areas and mining areas where mobile phone signals are weak or lacking, or in case the cellular network frequency bands (such as GSM, CDMA, 4G, 5G, etc.) on which mobile communications rely are not working, walkie-talkies are widely used in public safety, construction sites, logistics and transportation, leisure activities and other scenes, suitable for short-distance instant multi-person communication, and also suitable for occasions that require rapid communication and coordination, such as police, fire fighting, first aid, etc., to bring timely and effective communication functions. The embodiment of the present invention may include a walkie-talkie using a VHF or UHF frequency band, which is convenient for family members to communicate when traveling in mountainous areas, or for special use by small teams such as mountaineers and soldiers training in the frontier field.

[0082] The electronic communication cap provided by the embodiment of the present invention can be installed with a lithium battery with a capacity of 5000mAh inside the cap body, and two left and right miniature earphones are installed on the outer surface of the inner lining, and it also has the function of an intercom microphone. The earphone-microphone is required to have a power of 5 watts and is installed inside the top of the cap, so that the earphone-microphone has an intercom control chip and has a signal transmission and reception integrated with a simple high-frequency VHF or ultra-high frequency UHF transmission function. A hole is made in the center of the top of the cap to facilitate the placement of an antenna about 1 cm long on the outside, which is successfully combined after being encapsulated and waterproofed, and has an intercom function. The microphone-earphone is equipped with vibration control and a manual button switch. "Tap twice in a row" is used for listening, "tap once" is used for speaking, and the manual button is used as a switch.

[0083] The microphone and earphone speaker in the hat body have an intercom function; the flexible thin-film solar cell and the charging and discharging device in the electronic communication hat can just meet the requirement of the intercom function for sending and receiving wireless signals with a battery life of more than 8 hours. Compared with the battery life of general civilian walkie-talkies of less than 3 hours, the embodiments of the present invention greatly improve the battery life of the walkie-talkies.

[0084] Fig.10The present invention provides a logic control diagram of an electronic communication cap, wherein the core function of the microprocessor (CPU) is to execute programs, process data and control system operation, and usually adopts a high-performance, low-power processor architecture to support real-time computing requirements of audio-visual interfaces including intercom functions, mobile phones or AR glasses; the core function of the RAM in the memory module (RAM and ROM) is to temporarily store data and run programs, support fast data access and program execution, and the core function of the ROM is to store firmware and unchangeable programs to ensure the stability and reliability of the system; the core function of the power management (PMU) is to manage the charging and discharging process of the flexible thin-film solar cells, give priority to filling the attached charging and discharging devices, and do not rule out the possibility of locally supplying the generated photovoltaic power to the interconnected electronic communication equipment; the core function of the display interface is to drive and control the display modules of mobile phones and micro-display glasses, support high-resolution and high-refresh-rate display output, ensure the clarity and smoothness of the image, and switch the mobile phone display content to the near-eye display glasses when necessary; the core function of the sensor module is to connect and manage a variety of sensors, such as IMU (inertial measurement unit), optical tracking trackers, ambient light sensors, etc.; provide real-time posture, position and acceleration data of micro-display glasses, support interaction with mobile phone applications and GPS positioning, AI auxiliary functions; audio and video interface, audio processing, the core function is to process and output audio signals, support voice interaction and sound enhancement audio, micro-display audio, mobile phone audio (maximum 5 audio playback, including left and right earphones installed on the electronic communication hat, left and right speakers on the micro-display glasses frame, mobile phone speakers, and mobile phone speakers placed at the back of the hat brim, which can achieve surround effect), may integrate audio codec and microphone interface, support high-quality audio input and output; wireless connection, the core function is to support wireless communication technologies such as Wi-Fi and Bluetooth, realize data transmission and communication between the battery and other devices, and support remote control and data sharing; camera interface, the core function is to drive and manage the camera module on the edge of the micro-display glasses, support image capture and photography, video recording, support high-resolution image processing and real-time video streaming transmission, and optionally support gesture control menu selection; other interfaces, provide wired connection interfaces such as USB and HDMI, support fast data transmission and expansion functions with external devices. The AI ​​processing unit integrates AI technology and supports intelligent functions such as image recognition and voice recognition. It can improve the intelligence level of the electronic communication helmet and enable it to quickly respond to user needs.

[0085] Exemplarily, the driving device in the embodiment of the present invention also includes a mobile phone, which has been equipped with earphones-microphones and charging and discharging devices on the basis of the above embodiment. When the mobile phone is used outdoors to implement the GPS navigation mode with a power consumption of 10W, since the mobile phone is used in conjunction with the flexible thin-film solar cell, the diffuse illumination is 250W / m2 given in cloudy or overcast weather. 2Under the condition that 8 watts of power is obtained to supply the power consumption of the mobile phone, the battery life is: 4.42Ah·3.85 / (10-8)=8.5 hours; by comparison, the battery capacity of the mobile phone is 4422mAh. Given that its lithium battery voltage is 3.85V, if the user uses the mobile phone outdoors to implement the GPS navigation mode with a power consumption of 10W, the battery life is: 4.42Ah·3.85 / 10=1.7 hours. The embodiment of the present invention greatly improves the battery life.

[0086] Exemplarily, the driving device in the embodiment of the present invention also includes display glasses. In the embodiment of the present invention, a binocular display is used. A pair of armless AR smart glasses are selected and installed on the front inner side of the brim. Through a rotatable plastic shaft, one or two glasses can be flipped up, and the wearer does not use AR glasses at this time; or one or two glasses can be flipped down in front of the eyes, and the wearer uses AR glasses at this time. AR smart glasses are mainly based on micro organic light emitting diode (Micro-OLED) technology and optical waveguide technology. Micro-OLED has a single-eye resolution of 1080P, a brightness of 500-5000 nits, and supports a refresh rate of 120Hz. The glasses not only support high-quality display of videos and games, but also integrate micro cameras and photographic lenses. Through the FlymeXR 2.0 operating system, it supports a variety of interaction methods, including touch on the edge of the display glasses, voice assistants, and manual dial selection menus in the brim, providing a rich user experience. Fig. 9 The electronic communication cap is connected to the mobile phone and binocular display through the output interface USB Type C of the flexible thin film solar cell 10, and is connected through Fig.10 The logical control diagram shown enables coordinated use.

[0087] The advantage of this technology is that it can provide high-resolution and high-contrast images in a small size, which is suitable for scenes such as AR glasses that require compact display devices. Optical waveguide technology is one of the core technologies for AR glasses display. It uses the principle of total reflection of light inside the lens to transmit images from the micro display to the user's eyes. The display system of smart glasses provides an equivalent giant screen experience of 188 inches, supports a contrast ratio of 100,000:1, covers 108% of the sRGB color gamut, and can present rich colors and details; the embodiment of the present invention is different from AR glasses in that the display module and the speaker are integrated in the brim, the body and the top of the hat. The main advantage of optical waveguide technology is that it can achieve lightweight and high transparency, making AR glasses look the same as ordinary glasses while providing clear image display; considering the factors of sunlight in the wild, a pair of flip-up sunglasses are also configured on the outside of the AR display glasses, so that users can choose whether to use the sunglasses function.

[0088] The power consumption of display glasses varies in different scenarios. In simple text display and navigation, the main power consumption of eye display is to maintain the operation of the display screen and basic sensors (such as gyroscopes and accelerometers), and the power consumption is 1 watt, which is relatively low. When watching videos or movies, voice applications are better, and AI functions are used, the high brightness of the display screen, the image processing GPU and the mobile phone are used to the speaker, usually the power consumption is 1.5-2 watts, which is medium power consumption. High-resolution 3D display, virtual environment display, and complex navigation systems are required, and the power consumption is 3-4 watts, which is relatively high power consumption. Near-eye display consumes less energy than mobile phone display, which is conducive to energy saving and power saving, and increases the battery life of electronic communication hats.

[0089] When the user uses the mobile phone and 3D binocular display, the battery life is: 4.42Ah·3.85 / (10+4)=1.21 hours. If it is placed in an electronic communication helmet, the diffuse illumination is 250W / m in cloudy or overcast weather. 2 8 watts of power is obtained to supply the power consumption of the mobile phone, and the battery life is: 4.42Ah·3.85 / (10+4-8)=2.8 hours. After the battery of the mobile phone is exhausted, a 10Ah lithium-ion battery is also configured in the electronic communication hat, which can increase the battery life to: 10Ah·3.85 / (10+4-8)=6.3 hours. Therefore, installing AR display glasses and sunglasses on the brim of the hat not only reduces the burden on the bridge of the nose caused by the existing AR glasses being too heavy (the weight is generally 44-120 grams), but also greatly extends the battery life of AR glasses and mobile phones when used simultaneously. On cloudy days outdoors, the battery life is extended from 1.21 hours to 9.1 hours. Under clear and sunny conditions, the battery life is further extended, which greatly increases the battery life.

[0090] Exemplarily, the display glasses included in the driving device in the embodiment of the present invention are monocular displays. Based on the above embodiment, the monocular display can free up one eye to observe the environment and implement the fusion of virtual and reality. During the monocular display process, the glasses can be rotated to relieve the fatigue of close-eye reading or browsing web pages.

[0091] Since the translucent display AR glasses are fixed inside the brim, it ensures that the user can wear them naturally and comfortably for a long time. The left and right ear microphones and speakers are distributed on the left and right sides of the brim to ensure close-to-ear listening of voice playback, or user voice interaction, instructing mobile phones and displays. The shape of the electronic communication hat has both traditional elegance and a large surface area. Flexible thin-film solar cells are used to generate photovoltaic power under outdoor sunlight and indoor lighting to ensure continuous charging and power supply of the overall battery, greatly improving the battery life, and green energy saving, environmental protection, and carbon reduction. A microcontroller is set in the electronic pass hat. The microcontroller has a control chip that can be used to coordinate mobile phones, visual AR glasses displays, speaker playback and voice reception interaction, as well as to manage the power generation of flexible thin-film solar cells.

[0092] The electronic communication hat mainly includes the following parts: the hat surface is made of high-efficiency, flexible, and lightweight thin-film solar cells; speakers and microphones are installed on the left and right sides of the brim; a mobile phone insertion pocket and audio and video I / O port, as well as a DC charging and discharging port are installed on the back of the brim; flip-up thin and flexible display glasses, cameras, speakers, etc. are installed in the front of the brim; the microprocessor has a built-in control chip for automatically controlling and coordinating the functions of various integrated devices, flexible thin-film solar cells to generate electricity on-site for use in communication equipment, and charging and discharging devices to store excess electricity; connection and control of the mobile phone system; connection and control of the speaker / microphone system; connection and control of the display screen, video recording, photography system, etc.

[0093] Optionally, the electronic communication cap also includes: a buck-boost converter, and a charging and discharging device is located on the inner side of the cap body; the buck-boost converter is used to increase or decrease the voltage of the flexible thin-film solar cell.

[0094] Among them, the electronic converter is used to increase or decrease the voltage of the flexible thin-film solar cell, to adapt the voltage of various driving devices, and to meet the voltage requirements of various different driving devices; it can increase and decrease the voltage of the electronic communication cap and adjust the voltage and current as needed.

[0095] Optionally, the flexible thin-film solar cell includes at least one of a cadmium telluride solar cell, a perovskite solar cell, a copper indium gallium selenide solar cell and an organic thin-film solar cell.

[0096] Among them, the flexible thin film solar cell is a single-section solar cell or a multi-section stacked solar cell, and the multi-section stacked solar cell includes a double-stacked or triple-stacked solar cell. Perovskite solar cells and other flexible and thin photovoltaic technologies that can achieve weak light photoelectric conversion can be used for stacked photovoltaic technology. Other flexible and thin photovoltaic technologies that can achieve weak light photoelectric conversion include organic semiconductor photovoltaics, CIGS photovoltaics, inorganic semiconductor thin film photovoltaics such as cadmium telluride (CdTe), etc.

[0097] Optionally, the substrate of the flexible thin-film solar cell is a flexible transparent polymer substrate, the flexible transparent polymer substrate constitutes the outer side of the electronic communication cap, and the inner side of the electronic communication cap is provided with an inner lining; the material of the lining includes reinforced natural fiber cloth or synthetic fiber cloth; the material of the flexible transparent polymer substrate includes any one of polyimide, polyethylene naphthalate, and polyethylene terephthalate.

[0098] Among them, the light-absorbing materials of flexible thin-film solar cells are selected from photovoltaic materials with obvious performance in both strong and weak light, including cadmium telluride (CdTe), copper indium gallium selenide CIGS, perovskite metal halides, and organic semiconductors to form solar single-junction or multi-layer multi-junction solar cells, which meet the requirements of being light, thin and flexible, and having a photovoltaic power conversion efficiency PCE greater than 22%. The flexible thin film solar cell can be a double-stack perovskite solar cell, and the perovskite solar cell includes a flexible transparent polymer substrate, a first hole transport layer, a first perovskite absorption layer, a first electron transport layer, a conductive layer, a second hole transport layer, a second perovskite absorption layer, a second electron transport layer, an electron transport hole blocking layer and an electrode stacked in sequence; an indium tin oxide (ITO) conductive transparent polyimide film (thickness 25um) can be used as a flexible transparent polymer substrate, and a photoelectric conversion efficiency of 27.8% can be achieved through conventional material settings. The open circuit voltage of the double-junction perovskite solar cell is the sum of the two cells, reaching Voc=1.8V, and the short-circuit current varies greatly depending on the thickness of the two junction cells, the energy gap width, the use of the connecting conductive layer material and the process. The filling factor is 75-85%, and the overall power conversion efficiency of the two-junction solar cell can be improved by 10-40%. For example, using perovskite and organic semiconductor stacked double-junction solar cell technology, the existing technology can prepare a battery with an energy conversion efficiency PCE of 33%. Although the cost may increase, additional power conversion efficiency is obtained.

[0099] In order to meet the charging requirements of mobile phones, such as the standard charging voltage of 5V, the maximum current of 2A (maximum total power of 10W); the maximum charging voltage of Quick Charge can be from 5-12V, the current is 2A-1.67A (maximum total power of 20W). If the voltage is 12V and the current is 0.5-2A, it is necessary to use multiple single-cell perovskite batteries in parallel to increase the maximum open circuit voltage Voc. In the formation of perovskite batteries, the use of silver, copper, aluminum wire or its foil with good conductivity as the current collecting wire is conducive to the effective transmission of charge, reducing resistance and increasing voltage advantages. Under standard 1.5G light, the open circuit voltage of a single perovskite battery is Voc = 1.0-1.3V; the short-circuit current Jsc = 20-26mA / cm 2 In between, it can be adjusted according to the material formula and the degree of perfection of the manufacturing process.

[0100] The flexible thin-film solar cell used in the present invention is mainly made of perovskite ABX3 material; the following example illustrates the detailed preparation steps of a NIP single-cell perovskite solar cell. In actual preparation, it is not excluded but the reverse PIN single-cell solar cell can also be used. The preparation of perovskite flexible thin-film solar cells is a complex technology and process. The selection, preparation, module preparation and regional management of materials all affect the performance, cost and reliability of electronic communication caps.

[0101] Here is an example to illustrate the basic process of perovskite solar cells:

[0102] S1. Preparation of perovskite precursor solution: Perovskite materials are usually composed of organic metal halides, such as methylammonium lead iodide (CH3NH3PbI3). The use of modified perovskite compound formulas is not excluded here, and other A, B and other halogens X (such as I, Br, Cl) are used to adjust the semiconductor energy gap Eg (eV), increase stability, indicate battery current, fill factor FF and other measures. The preparation of the precursor solution requires dissolving organic cations (such as methylamine) and metal halides (such as lead iodide) in a suitable solvent, which is usually highly soluble, highly polar, low in toxicity, and has a high boiling point (greater than 100°C), such as dimethylformamide (DMF) or dimethyl sulfoxide (DMSO). The selection of solvents may also include the addition of other auxiliary chemicals such as passivating the surface of the crystal material and improving the 2D and 3D perfection of the thin film crystal.

[0103] S2. Flexible transparent conductive substrate: Indium tin oxide (ITO) or fluorine-doped tin oxide (FTO) conductive plastic is usually used as the substrate. The plastic used as the flexible substrate can be PI polyimide, polyethylene naphthalate PEN, polyethylene terephthalate PET, etc. These substrates have good conductivity and light transmittance as well as mechanical strength and weather resistance, and are important components of perovskite batteries.

[0104] S3. Preparation of electron transport layer (ETL): Deposit the electron transport layer (ETL) on the substrate. Commonly used inorganic materials are titanium dioxide (TiO2) or modified tin oxide. Organic electronegative materials can also be used, such as charge-deficient fullerene C60 and its modified compounds, or other organic electronegative materials, such as BCP (2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline). The preparation of ETL can be achieved by spin coating, spray pyrolysis or chemical vapor deposition (CVD); for organic ETL materials, vacuum evaporation film forming can also be used. The function of ETL is to promote the transmission of electrons and prevent the transmission of holes.

[0105] S4. Preparation of perovskite light-absorbing layer: drop the perovskite precursor solution on the substrate, and then use blade coating, spin coating or slit casting to spread the solution evenly and form a thin film, and then further dry it. The thickness and uniformity of the film are crucial to the performance of the battery. For large-scale preparation, physical vapor deposition (PVD) and chemical vapor deposition (CVD) can also be used, which are suitable for the preparation of large-area devices. The vapor deposition method can avoid the use of solvents in the spin coating method, but the equipment requires a higher investment. The subsequent surface treatment process of the film and the improvement of the crystal film also have a great impact on the efficiency and life of the solar cell.

[0106] S5. Preparation of hole transport layer (HTL): The function of HTL is to extract and transport photogenerated holes. The hole transport layer (HTL) is deposited on the perovskite layer. The commonly used material is Spiro-OMeTAD [2,2',7,7'-tetrakis(N,N-p-methoxyanilino)-9,9'-spirobifluorene, N2,N2,N2',N2',N7,N7,N7',N7'-octakis(4-methoxyphenyl)-9,9'-spirobifluorene-2,2',7,7'-tetramine, CAS: 207739-72-8]. Other HTL organic materials or inorganic materials such as MnO3 can also be used. The use of conductive polymers can provide flexible and thin-film HTL functions, such as PEDOT:PSS conductive polymers, which are polymers of EDOT (3,4-ethylenedioxythiophene monomer), and PSS is polystyrene sulfonate. These two substances together greatly improve the solubility of PEDOT and facilitate solution film formation.

[0107] S6. Preparation of metal electrodes: The function of metal electrodes is to collect charges and connect to external circuits. Metal electrodes are deposited on HTL by vacuum evaporation or sputtering technology. Commonly used materials are gold (Au) or silver (Ag) or copper (Cu) carbon electrodes with good conductivity and high stability.

[0108] S7. Packaging: Packaging is an important step to protect the battery. Usually, the photovoltaic backplane available in the market is used for flexible photovoltaic backplane packaging, such as commercially available PVB or POE, supplemented with butyl hot melt adhesive to prevent water, oxygen and other external factors from corroding the battery, thereby improving the stability and life of the battery. The surface treatment of the device before packaging can also add moisture-absorbing substances, environmentally friendly absorption of metal escape and other functional layers.

[0109] S8, Testing and Characterization: The prepared cells were tested for photoelectric performance, including open circuit voltage Voc, short circuit current Isc, fill factor FF, and photoelectric conversion efficiency PCE. AM 1.5G was used to simulate the average solar illumination on Earth (1000W / m 2 ) The aging life is compared under double 85 (temperature 85°C and humidity 85%), and the long-term stability test is performed to evaluate the performance degradation of the battery under environmental conditions. In order to meet the above functions of the present invention, the battery working life (maintaining the initial PCE of at least 85%) is required to be greater than 4 years.

[0110] The preparation of perovskite solar cells involves multiple key steps, from material preparation to packaging and testing, and each step has an important impact on the performance and stability of the battery. By optimizing these steps, the photoelectric conversion efficiency of the battery can be improved, the production cost can be reduced, and the service life of the battery can be extended. The industry's current single-cell perovskite solar cell has an optimized Voc = 1.18V, Isc = 26.99mA / cm2, power conversion efficiency PCE = 26.4%, and a long-term life of up to 5 years, which basically meets the use requirements of electronic communication helmets and maintains the energy consumption requirements of mobile phones.

[0111] Considering that the electronic communication cap of the present invention is a cap that can generate electricity using solar energy, it can be used both indoors and outdoors. Under indoor lighting or when the outdoor sunlight is not too strong, it is crucial to ensure the use of photovoltaic power supply. Under bright outdoor sunlight, the normal sunlight illumination is 500-1200W / m 2 Under low light conditions, which is equivalent to 63K-130K lux, power generation of electronic communication caps is not a problem. Under indoor lighting, laboratory and operating room lighting at 1000-5000 lux is not a problem. In other indoor places such as shopping malls (usually 500-1000 lux of illumination), offices (usually 300-500 lux of illumination), and residences (generally 100-300 lux of illumination), it is also necessary to ensure the power generation function of the electronic communication cap, which requires that the electronic communication cap used must be selected from the following photovoltaic technologies: flexible thin-film solar cells with a photoelectric energy conversion efficiency PCE of 20-50% under low light conditions. Flexible thin-film solar cells can be solar cells that meet the above PCE power generation requirements, preferably perovskite thin-film solar cells, or they are combined with organic semiconductor thin-film solar cells to form a stacked double-junction solar cell. Under artificial LED lighting (5500K, 1000Lux), the power conversion efficiency PCE of perovskite solar cells can exceed 20%, while traditional crystalline silicon solar cells are usually 10% or less, which is mainly due to the sensitivity of silicon-based cells to the spectrum and the low charge collection efficiency under low light conditions. The use of perovskite materials, which have higher visible and near-infrared spectrum absorption coefficients and charge mobility, can achieve a photoelectric conversion efficiency greater than 22% in weak light (such as indoor lighting), for example, under a TL84 light source of 1000 lux, using stacked cells, such as double stacked cells.

[0112] Since mobile phones, display glasses, and batteries all have specified DC voltage and current value requirements, Figure 8In the connection method shown, when the sub-solar cell is Vx, the overall voltage of the sub-solar cell assembly is 6Vx. In the single-cell state, the maximum voltage is 1.3Vx6=7.8V, which can meet general charging requirements; when using a double-stacked solar cell as a photovoltaic panel, the maximum output voltage is 2.7Vx6=16V, which can meet the fast charging range requirements.

[0113] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0114] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
