FIG. 2 is a view showing a laser beam position locator 34 composed of a lattice pattern according to an embodiment of the present invention.

Referring to FIG. 2, the laser beam position checker 34 is a device configured to identify the position of the solar cell 32 in order to identify the position information of the laser beam transmitted to the solar cell, . The laser beam position checker 34 may be formed of a transparent film, a glass, a panel, or the like, which can be attached to a solar cell and can transmit a laser beam, since it needs to confirm positional information of the laser beam reaching the solar cell .

Referring to FIG. 2, in order to confirm the positional information of the laser beam, four pieces of data (line number, column number, horizontal / vertical, intensity) Can be defined. In the position information, the vertical / horizontal information is defined as 0 in the case of horizontal and 1 in the case of vertical.

For example, the position information data of the first horizontal line 210 on the upper left of the solar cell grid of FIG. 2 is (1,1,0) and the position information data of the second horizontal line 230 on the upper left of the solar cell grid is , 2,0). 2, the position information data of the first vertical line 250 on the upper left of the solar cell grid is (1,1,1) and the position information data of the second vertical line 270 on the upper left of the solar cell grid is (2,1,1 ).

In FIG. 2, the laser beam position determiner 34 is configured as a grid pattern. However, it is also possible to configure each zone as a circular, square, or other pattern so that the position of the laser beam can be confirmed in the solar cell 32.

The communication module 36 may serve to communicate with the laser beam receiving apparatus 30 so as to exchange information with the laser beam transmitting apparatus 10. For example, the laser beam receiving apparatus 30 transmits the reception information indicating whether the laser beam is received from the laser beam transmission apparatus 10 and the position information of the laser beam reaching the solar cell to the communication module 36 To the laser beam transmission apparatus 10 via the transmission line. For example, the communication module 36 may include at least one of a WiFi module, a bluetooth module, a radio frequency (RF) module and a WLAN module to exchange information wirelessly with the laser beam transmission device 10 .

[ The controller 38 can receive status information of the laser beam transmission apparatus 10 through the communication module 36, that is, status information such as a laser beam transmission status and a laser angle from the laser beam transmission apparatus 10.

3 is a flowchart illustrating a method of transmitting a laser power for recognizing a center of a solar cell according to an embodiment of the present invention.

In step S10. The signal processor 18 controls the laser beam expander 14 to search for the laser beam receiving device 30 to enlarge and transmit the laser beam to the maximum size. The signal processor 18 can roughly determine the position of the laser beam receiving apparatus 30 using the communication modules 16 and 36 including the GPS module and enlarges and transmits the laser beam to the maximum size, (10).

In step S20, the signal processor 18 can receive the transmitted laser beam from the laser receiving device 30 through the communication module 16, or can receive the laser beam receiving information from the laser receiving device 30. That is, the controller 38 controls the solar cell 32 and the laser beam position checker 34 to determine whether or not the transmitted laser beam has been received by the laser beam receiving apparatus 30, When the information is transmitted to the laser beam transmission apparatus 10 using the communication module 36, the signal processor 18 receives the laser beam reception information from the laser beam reception apparatus 30 through the communication module 16 have.

In step S30, in order to confirm the position of the solar cell center, the signal processor 18 controls the laser beam expander 14 based on the received information of the received laser beam to transmit the laser beam in the size of the solar cell grid . That is, since the laser beam position determiner 34 configured to check the position of the laser beam in the grid pattern or each grid is attached to the solar cell 32, in order to confirm the position of the solar cell center, Can be transmitted in a grid pattern size.

In step S40, the signal processor 18 can confirm the position information of the transmitted laser beam. That is, the controller 38 controls the solar cell 32 and the laser beam position determiner 34 to determine the laser beam position information of the laser beam of the grid pattern size transmitted to the zone of the solar cell grid, When the determined laser beam position information is transmitted to the laser beam transmission apparatus 10 using the communication module 36, the signal processor 18 transmits the laser beam position information to the laser beam reception apparatus 30 via the communication module 16. [ And confirm the position information of the transmitted laser beam.

In step S50, the signal processor 18 can change the laser angle so that the laser beam is located at the solar cell center based on the position information of the identified laser beam. For example, referring to FIG. 2, the signal processor 18 can obtain four data sheets of position data and integrity of the laser beam received in the solar cell and compare it with the solar cell center position data, It is possible to estimate and change the laser angle to be located at the solar cell center.

In step S60, the signal processor 18 can transmit the laser beam at a changed laser angle in a solar cell grid size.

In step S70, the signal processor 18 can confirm whether the emitted laser beam is located in the solar cell center. That is, the signal processor 18 can determine whether the transmitted laser beam is located at the solar cell center by determining whether the data of the laser beam position information sent from the controller 38 coincides with the position data of the solar cell center. The signal processor 18 can repeat the process from step S40 to step S60 so that the dispensed laser beam is located at the solar cell center so that the dispensed laser beam can be positioned at the solar cell center.

The signal processor 18 analyzes the intensity of the laser beam received in the solar cell 32 and confirms the distance information between the laser beam transmission apparatus 10 and the laser beam reception apparatus 30 in step S80. The distance information between the two devices can be checked by comparing the GPS information between the laser beam transmission device 10 and the laser beam reception device 30. However, accurate distance calculation is required to estimate the maximum power transmission efficiency, The distance information between the laser beam transmission apparatus 10 and the laser beam reception apparatus 30 can be confirmed by analyzing the intensity of the received laser beam.

In step S90, in order to transmit the power to the laser beam receiving apparatus 30, the signal processor 18 sets the laser beam around the solar cell center to have the maximum power transmission efficiency based on the confirmed position information and the distance information Cells can be transmitted at full size. That is, the signal processor 18 controls the laser source 12 and the laser beam expander 14 so that power is transmitted from the laser beam transmission apparatus 10 to the laser beam reception apparatus 30 at the maximum power transmission efficiency, The laser intensities can be controlled and transmitted to the entire cell center around the cell center.
