The conventional solar cell phone charger is composed of a battery and a fixed memory, and has a function as an emergency power supply and a data storage device.

In addition, the half-cutting scribing / breaking method of the present invention reduces melting and solidification due to laser heat on the solar cell cutting surface, which is a disadvantage of the laser pull cutting or the braking method used in the conventional small solar cell manufacturing method.

2 is a block diagram of a solar charger for a mobile phone having an SD (or HSD) card reader function according to the present invention.

As shown, the solar charger according to the present invention is a multi-module solar cell 100, battery 200, USB port 300, SD (or HSD) card reader 400, control circuit 500 and high brightness LED 600 is made.

The biggest feature of the present invention is a large feature in the multi-module solar cell.

The multi-module solar cell 100 is composed of 5 to 15 solar cells, preferably 8 to 10 solar cells, and is connected in series to output a voltage of 5 to 6.5 V, respectively, without a separate boosting process. The battery charges as it is stored directly in). This can be used to maximize the solar cell efficiency without power loss.

The solar cell module used in the conventional mobile phone has a low voltage output according to the limitation of the volume for use in the mobile phone. Generally, the generation voltage of commercially available small solar cells (mother solar cells) is 0.5V or less, and two or three small solar cells require a voltage amplifier to be used as a cell phone battery (eg IC chip and This amplification process has the bad effect that the efficiency of the original solar cell is reduced by 20-30%. In addition, when the volume of the solar cell is large, when using several at once, the volume is too large to have a disadvantage that can not be used as an auxiliary charger that requires a small volume.

Therefore, the present invention provides a solar cell that maximizes the efficiency of the solar cell does not require such a voltage amplifier.

In another aspect, the present invention provides a method for manufacturing a small solar cell module having a special technical feature and a solar cell module manufactured by the method to provide a highly efficient and compact solar cell and as a result provide a small auxiliary charger You can do it.

In the double-sided electrode module of the present invention, a process of half cutting a solar cell by laser scribing, a full cutting of the half-cut solar cell by a braking operation, and a (+) terminal and a (-) terminal on one side of the front surface Forming and manufacturing a solar cell electrode substrate having a structure in which the (+) terminal and (-) terminal in series on the back, the (+) bus bar of the full-cut small cell is the cell electrode substrate After connecting by connecting with (+) terminal with solder cream, soldering and connecting with (-) bus bar of small solar cell and (-) terminal of solar cell electrode substrate with connecting element, laminating after the final process Provided are a method for manufacturing a small solar cell including a process and a small double-sided electrode module.

In addition, the back electrode solar cell module of the present invention is a process of half-cutting a cell by the laser scribing, a full-cutting of the half-cut solar cell by a braking operation, (+) terminal and (-) terminal on both sides Is formed and fabricates a solar cell electrode substrate configured to connect small solar cells in series. The solar cell is serially mounted by mounting a rear electrode small solar cell on the solar cell electrode substrate and soldering the small solar cell with solder cream. Connecting process,

Provided are a method for manufacturing a small solar cell and a small back electrode solar cell module including laminating after the above process.

As shown in FIG. 4, the small-sized solar cell module manufacturing process of the present invention uses the ultra-precision laser scribing technique to half-cut the cell by optimally adjusting the processing conditions of the laser, that is, the scan speed, the pulse period, and the oscillation time. , The cell is completely cut by the braking operation to manufacture the unit cell (which means the cutting cell of FIG. 5 ). A small unit solar cell is mounted on a solar cell substrate (PCB substrate) having a special technical feature of the present invention. A method of manufacturing a small solar cell module and a small solar cell module by arranging the solar cells on the solar cell substrate as described above and then soldering and then laminating using EVA, PET, or tempered glass. to provide.

The present invention has a special technical feature on the solar cell substrate (PCB substrate) as described above. Conventional solar cell module PCB substrate is difficult to assemble the solar cell by using a method of connecting the solar cells using the wiring, not only takes a long time but also a high failure rate, the present invention requires wiring The present invention provides a method of designing a solar cell substrate, which significantly reduces manufacturing time and defect rate of a small solar cell module, and a small solar cell module.

The small solar cell module of the present invention starts by performing a process of cutting a mother solar cell into a unit cell using a scribing technique, and a method of half cutting a unit solar cell. It is prepared as follows. One of the technical features of the present invention is to half-cut the solar cell.

In general, the method of cutting any material can be carried out by physical and chemical means. Various cutting means, such as a method of applying an external force, a method of chemically cutting, or a method of using a laser, may be used according to the physical characteristics such as the type or strength or hardness of the material to be cut.

Therefore, the present invention is carried out by half-cutting the cutting cross-sectional area of the solar cell using any of the above methods. Recently, a method of cutting a material using a laser is known in detail among the cutting methods. In the present invention, cutting by scribing (cutting) using a laser is efficient and preferable.

As a method of irradiating a workpiece with a laser beam to remove a small amount, scribing, trimming, mask making and mask repair, engraving, etc., in the present invention, Ice cutting is efficient. Scribing generally refers to a method of making a groove using a diamond scriber when cutting a semiconductor wafer and then breaking the wafer by applying stress to the back side of the wafer. Although many diamond scribers are used in the scribing process, scribing using a laser is also widely used. Therefore, the present invention may use a scriber such as diamond, but scribing using a laser is more preferable.

Diamond scribing is efficient because laser scribing has the disadvantage of having a large cutting width, defects at the tip of the material, and minute cracks that affect the performance of the solar cell device. This is because laser scribing can sharpen the end shape of the cutting groove very much and concentrate the stress on the very sharply formed groove when stress is applied so that the cutting of the solar cell is very easy and the cutting surface is clean. Moreover, in the related art, full cutting for completely cutting a solar cell through laser scribing has been performed, but such a full cutting has a disadvantage of lowering the efficiency of solar cell engraving. In addition, the full cutting using this laser was mainly suitable for manufacturing a large-sized solar cell. In general, when cutting a solar cell using a laser, a small solar cell is manufactured because the cutting edge of the solar cell is melted and solidified again by laser heat, thereby causing a problem of significantly deteriorating the function of the solar cell. Because it was very unsuitable.

In particular, when a small solar cell is completely cut through laser scribing, the cutting surface is melted by the heat of the laser and cooled again, which significantly reduces the function of the solar cell. Therefore, it cannot be used as a small solar cell that can be used for IT equipment. .

Furthermore, considering that the size of the small solar cell is 4mm ~ 10mm, it can be said that the function of the small solar cell is completely deteriorated when the laser is used for full cutting. Therefore, through such a conventional scribing it is impossible to manufacture an intact solar cell module.

On the other hand, the present invention can manufacture a complete unit solar cell through a process of half-cutting a solar cell using laser scribing and then completely cutting it in a breaking process. Such half-cutting scribing / breaking process of the present invention can be said to be one of the technical breakthroughs in the manufacture of small solar cells. Laser half-cutting of a cell means cutting 45 to 60% of the cell cross-sectional area, and when in this range, a clean solar cell cross section can be obtained for the next braking operation. You will be able to produce.

Laser scribing generally uses pulsed lasers and must be drilled at regular intervals rather than overlapping pulses. The repetition rate of energy per pulse is selected in consideration of the shape of the pulse. Although the type of laser varies depending on the material, 355 nm, 532 nm, and 1064 nm high power pulse lasers are widely used.

Therefore, the present invention is to use the ultra-precision laser scribing technology to half-cut the solar cell by optimally adjusting the laser processing conditions, ie scan speed, pulse period, oscillation time, etc., for the solar cell material. Such processing conditions can be obviously performed by those skilled in the art. That is, according to the linear width and length of the electrode pattern, the processing conditions such as the energy intensity and the scanning speed of the laser beam can be controlled together with the characteristics of the substrate to be processed such as thermal conductivity. Therefore, depending on the line width and length, the laser head is finely controlled on the X-axis or Y-axis, or the initial output is monitored at the initial stage every such X-axis Y-axis movement. By controlling the energy, pulse, etc., the energy intensity can be adjusted to half-cut the solar cell.

After the scribing, the brake process means that the solar cell is completely cut by applying stress to the half-cut solar cell as described above. That is, the half-cut solar cell mentioned above is subjected to a process of cutting the solar cell by braking. The brake process is generally a process of placing a brake bar on a solar cell on which a minute crack-shaped cutting line is formed and applying a momentary force to the solar cell. In a typical brake process, instantaneous and strong force is transmitted to the solar cell in which the crack is formed, and defects of the cutting surface are increased due to minute pieces during cutting, and the performance of the solar cell is reduced. Particularly, in the case of the conventional small solar cell, a very small solar cell is manufactured, and thus the defect rate is higher and the performance of the solar cell is significantly reduced.

However, by performing the half cutting in the scribing process and then completely cutting in the brake process as described above in the present invention, it is possible to significantly lower the defective rate and increase the performance, which is the aforementioned problem. As such, it is a feature of the present invention that the half cutting scribing / breaking process can dramatically increase the performance of a small solar cell.

Another technical feature of the present invention lies in the specificity of the substrate which drastically improves the problem of the conventional solar cell substrate, thereby eliminating the inconvenience of assembly and also reducing the defective rate.

Conventional solar cell substrates use a PCB (Printed Circuit Board) plate using a variety of materials. As shown in FIG. 5, the conventional solar cell PCB board has a (-) bus bar at the center of the cell after aligning the solar cells in which (-) and (+) devices are formed on the cell support substrate in a row. The solar cell module was completed by zigzag-connecting "connectors" commonly referred to as ribbons with the positive and negative bus bars. However, when manufactured by the conventional method in a small solar cell module, assembling the unit cell, ie, aligning it on the substrate, is not only a difficult process, but also connecting the unit cell once aligned and fixed to the connection element. In addition, the manufacturing process takes a long time due to the difficult process, as well as a large increase in the defective rate.

However, in the solar cell substrate of the present invention, (+) terminal and (-) terminal are formed on one side of the front surface, and the (+) terminal and (-) terminal in series on the back surface. The unit cell is mounted side by side with the same electrode terminal facing the same direction on one side of the front side of the electrode substrate, but the positive bus bar of the solar cell is The technical feature is that it is soldered to the (+) terminal and the (-) bus bar of the solar cell is configured to be soldered to the (-) terminal on the front of the substrate.

As the solar cell substrate structure is taken, solder cream is applied to the same electrode terminal (specifically, the (+) terminal), and the (+) bus bar of the unit cell is mounted side by side so that it is naturally bonded to the (+) terminal. do. In addition, the (-) bus bar of the unit cells is oriented side by side in the opposite direction of the (+) bus bar. Therefore, the connection between the (-) terminal of the solar cell board and the (+) bus bar of the unit solar cell is simple. Soldering not only makes the production considerably easier, but also enables large-scale production and standardizes the process, resulting in an automated process.

In particular, in the case of small solar cells, such a large-scale manufacturing process was not possible in the past, but the process according to the present invention can be applied to small solar cells, thereby achieving the effect of shortening the manufacturing time and remarkably reducing the defective rate.

Referring to the solar cell substrate of the present invention in more detail, (-) and (+) terminals are formed in a zigzag form on one side of the front surface of the solar cell substrate. Zigzag type means that the (-) terminal and the (+) terminal are sequentially formed at regular intervals.

On the back surface of the solar cell substrate, the negative terminal and the positive terminal are connected in series. (-) Terminal is connected to (+) terminal and (+) terminal is connected to (-) terminal, but (-) terminal and (+) terminal, which are the first and last terminals, are not connected It means that it is formed in a good position to output power.

In addition, unit cells are arranged side by side on the (-) and (+) terminals which are formed in a zigzag pattern with a predetermined pattern on the front surface of the electrode substrate. In this case, the unit cell is characterized in that the negative bus bar and the positive bus bar are formed on one side. The negative bus bar and the positive bus bar of the unit cell can be formed on one side because the half cutting scribing / breaking process is used as described above. Therefore, a conventional unit solar cell is formed with a negative bus bar and a positive bus bar at the center of the unit cell, and there is a remarkable difference from connecting the ribbon with a connecting element.

Of course, in the past, various PCB substrates are created and have various names to be utilized. For example, there is a flexible printed circuit board (FPCB) of Patent No. 10-0416139, which not only complicates the manufacturing of the substrate but also takes the method of soldering the conductive film exposed through the front opening, which adds to the cumbersome process. I just let you.

However, unlike the conventional method, the solar cell electrode substrate of the present invention applies solder cream to the (+) terminal of the electrode substrate as described above, so that the (+) bus bar of the unit cells is parallel to the (+) terminal of the electrode substrate. It is possible to join. This effect enables the innovation of the solar cell deployment interval. In addition, the joints can also be exactly matched at the same position, so the joining effect is significantly increased. As described above, the (-) bus bars of the unit cells that are aligned not only point in the same direction but also form the same spatial coordinates, so that the (-) bus bar of the solar cell and the (-) formed at a predetermined position on the electrode substrate The terminal can be soldered simply by using a connection element. As shown in Fig . 6, the connecting element can be freely used in any form such as a Z-shaped S-shaped one-shaped shape.

In addition, the present invention, in addition to the manufacturing of the double-sided electrode cell module as described above, in the case of the back-electrode solar cell module, the solar cell substrate is provided with (+) terminal and (-) terminal on each side, but if the unit cell is mounted in series It consists of a configuration that makes the connection.

The solar cell module is fabricated by mounting a unit cell on such a solar cell electrode substrate and soldering with a solder cream so that the unit cells are connected in series.

For example, as shown in FIG. 7, a back electrode solar cell substrate has a positive terminal and a negative terminal formed thereon, and when a unit solar cell is mounted, one unit of the solar cell electrode substrate is used as two unit cells. The side connects only the (-) pole and the other side connects only the (+) pole so that the unit solar cells are connected in series.

 The solar cells connected in this way are unit solar cells connected in series to be completed as a solar cell module that generates a voltage capable of functioning as a battery of an electronic product.

 In addition to the present invention, the above-described back electrode unit cell is a technical feature of the back electrode solar cell module. The half-cutting of the solar cell by the laser scribing and the half-cutting of the solar cell are performed by the braking operation. It is advantageous to use the one manufactured by the cutting process in terms of the functional aspects and the efficient generation of power.

After the above process, the present invention provides a method for manufacturing a small solar cell including a laminating process to be described below, and a small back electrode solar cell module accordingly.

As such, when a plurality of unit solar cells are disposed on the solar cell substrate and soldered, the lamination process is then performed. Laminating is a process of forming a transparent barrier film in order to prevent oxidation and breakage by air of the solar cell. In general, the laminating material may be a polymer and glass such as polyethylene, polypropylene and the like, preferably EVA, PET or tempered glass. Such a laminating step can be performed in a usual laminating step, of course.

Even after the laminating process or before the process, when the electrode is attached to the first and last terminals of the (-) and (+) terminals of the solar cell substrate of the present invention and used as a power source, a small solar cell module is completed.

The solar cell of the present invention does not need to boost the output voltage by converting light energy into electrical energy using the irradiated sunlight as described above, and the solar cell is generated as a module composed of 5 to 15 cells. Does not take much time to charge the battery.

The control circuit 500 controls the SD card reader 400 and the high-brightness LED 600, and controls the USB port 300 to enable charging via the USB port 300 of the Bluetooth 800 device to be described below. To control the power supply.

Meaning of the control circuit of the present invention means a conventional device for controlling the current or voltage supplied to the battery, card reader, LED, USB port, Bluetooth to be described below. Such a control circuit also performs a function of controlling the current and voltage of the battery of the present auxiliary charger.

The control circuit of the present invention is generally a concept that includes a current control circuit for controlling the total current supplied to the load and the battery from a current source having a limited capacity and is also applied to each device as a function of controlling the total current. It means a circuit that controls the voltage load.

Therefore, the present invention is preferably a control circuit that can apply all the amount of current supplied to the main body of all functional communication terminals, such as smartphones, iPhones, etc. recently released by various companies, that is, any range of the range required by the main body of the communication terminal It consists of a control circuit that can supply and control the amount of current.

This feature provides a compatible secondary charger that is also compatible with certain communication terminals that have a constant current, such as a range of 500mA to 1A.

In addition, the control circuit 500 stably controls the voltage supplied from the solar cell to the battery 200 and performs a function of controlling the high brightness LED 600.

The USB port 300 is provided with a function to charge the battery using an external device. That is, when an external device is connected to the USB port 300, the battery 200 is charged with energy from the external device transmitted through the voltage bus under the control of the control circuit 500.

The card reader of the present invention refers to a device that reads and transmits storage information of an external memory card mounted on a communication terminal body through a USB port.

Currently, memory cards come in many varieties including MMC (Compact Flash Card), CF (Compact Flash Card), SMC (SmartMedia Card), MS (Memory Stick) and SD (Secure Digital Memory Card). In addition, many different small cards such as Mini SD, MS Duo, and Trans Flash (Micro SD) are sold commercially.

In the present invention, a card reader capable of reading any of the above-described types of memory cards may be used, but preferably, an SD card reader (or HSD card reader) that is widely used in a communication terminal is preferred. In addition, the present invention has a configuration that can be applied to a P RAM (RAM) type memory.

The SD card reader (or HSD card reader) 400 of the present invention is connected to an external storage device such as a PC through a USB port 300 without a separate connection cable, so that data of a memory card of a mobile phone is transmitted. That is, the USB input / output unit exchanges data between the memory card inserted into the memory card reader and the main device (external device, PC, etc.) using the USB interface.

Therefore, the SD card (or HSD card) embedded in the mobile phone is compatible with the SD card reader (or HSD card reader) to transfer data to an external device without a separate cable.

In addition, the built-in SD card reader allows instant backup of data stored in IT devices such as mobile phones. Currently, mobile phone functions have many functions such as taking pictures and videos, downloading data through the Internet, but the capacity of the built-in SD memory (or HSD memory) is limited. This data can be stored and other tasks immediately through the SD card reader function of the solar charger for mobile phones with the SD card reader function.

In addition, the present invention can change and exchange the data capacity of the SD card according to the user's arbitrarily increases the user's convenience.

Another technical feature of the present invention is that it has a Bluetooth function capable of wirelessly transmitting data of the memory card as shown in FIG. 3.

Bluetooth of the present invention can be controlled by the control circuit current or voltage as described above is a stable drive.

Bluetooth is a short-range wireless communication technology that can transmit information such as text data, voice data, and video data at a maximum speed of 1 Mbps over a distance of 10 to 100 m. In recent years, the technology has been further developed, which is possible over longer distances and has increased transmission.

Bluetooth devices that can communicate with each other by the Bluetooth communication method can establish a connection state through which communication such as Inquiry, Inquiry Scan, Page, and Page Scan can be performed. Configure. this

In the process, a master device and a slave device are determined according to their roles.

If you want to configure a new connection between the Bluetooth devices, you must match the operating clock and frequency pattern between the Bluetooth devices. Inquiry during the process of configuring the connection state refers to an operation of repeatedly transmitting the operating frequency from the master so that the slave device can match the frequency pattern with the master device. Inquiry scan is a process performed by the slave device to detect a received frequency and synchronize with the detected frequency. Page refers to the process of sending a clock signal from the master device so that the slave devices can match the master's operation clock, and page scan refers to the slave device detecting and synchronizing the received clock. Through this process, a network formed by connecting one or more slave devices to a master device is called a piconet.

According to the presently proposed Bluetooth communication method, one master device in a piconet can communicate with each other by connecting seven slave devices in an active state. In addition, in order to connect a new slave device to the piconet, the master device breaks the active connection to any one slave device among the seven slave devices connected to the active state and performs the communication connection of the new slave device with the active state. do.

On the other hand, in the Bluetooth communication method, an active mode for performing normal communication with a slave device and a hold / sniff / park mode for saving power of the communication device are mastered. The device and the slave device operate. Hold mode is a typical mode used when there is no need to send data for a relatively long time. The sniff mode is a mode for transmitting and receiving data for a predetermined period from a specific time set between a master device and a slave device. The park mode is a mode in which the slave device intermittently communicates with the master device and the slave device in order to request synchronization with the master device and switching of the active mode.

The slave device operating in one of the active mode and the hold / sniff / park mode performs the operation of the mode repeatedly with a predetermined period. On the other hand, a slave device operating in hold mode is a repetitive main

It can be regarded as a periodic operation like other modes because it is a one-time operation mode without a device, or because a slave device at a given time wakes up (drives) to communicate with the master device.

At this time, when the slave device connected to the master device is converted to the corresponding mode, the master device sets the communication allocation time with each slave device in the corresponding mode through a communication negotiation with the slave device to be converted mode. These slave devices are set to operate with periodicity for the mode through negotiation with the master device. Therefore, conventionally, the master device and the slave device communicate with each other fixedly with the communication allocation time and period set by mutual negotiation until the mode of the slave device is changed.

Recently, conventional wireless telephone systems used by portable terminals such as Personal Communications Services (PCS) and cellular phones have a problem of paying a large fee compared to landline telephone systems.

Therefore, a portable terminal equipped with a Bluetooth module can be used as an intercom handset by connecting with an intercom in an office, as a wireless telephone handset by connecting with a base station of a cordless phone in a home, and as a mobile phone when moving.

I'm suggesting a way to do it.

The present invention is equipped with a Bluetooth module as described above in the auxiliary charger of the present invention provides a Bluetooth function capable of wireless communication to an external device.

The external device refers to a device capable of communicating a concept including all mobile phones, smart phones, MP3, MP4, PMP, PC, notebook, and other IT devices.

With this Bluetooth function, data read by SD (HSD) card reader can be transmitted or received to external devices such as mobile phones, smartphones, MP3, MP4, PMP, PCs, laptops, etc. Will provide an effect.

In addition, the Bluetooth of the present invention also provides an advantage of not having to consider the burden of power in use by using a power source using sunlight, which is a great advantage of the present invention.

In addition, the high brightness LED 600 of the present invention is powered from the battery takes a configuration that can be used according to the needs of the user in a dark place or a dark night.
