A solar component and its encapsulation method and special encapsulation tool

Abstract

The invention discloses a solar component, which includes a PCB plate and a plurality of solar cells. The solar cells are arranged on one side of the PCB plate and electrically connected with the PCB plate by contact conductors from a main grid line of each solar cell. And the number of the contact conductors from the main grid line of each solar cell is two at least. In addition, two joints are positioned between the back of the solar cells close to lateral sides and the PCB plate. One joint is a weld joint provided with pastes and the other joint is a bonding part provided with adhesives. The invention also further discloses encapsulation tools for the solar component and the encapsulation method of using the encapsulation tools to manufacture the solar component. The encapsulation tools and the encapsulation method can be used to effectively prepare the solar component with high quality, and the solar component is not disintegrable in the welding course and the multiple contact conductor guarantee the circuit security in use.

Description

technical field [0001] The invention belongs to the field of solar cells, and in particular relates to a small-sized solar module, its packaging method and a special packaging tool. Background technique [0002] With the continuous development of human beings, energy consumption is increasing, making the related technology of solar modules a hot issue of great concern to the whole society. For the solar module itself, its working life is directly related to the packaging process. In the prior art, Chinese patent CN200520069876 discloses a circuit device of a solar lamp, the device includes a solar cell, a control circuit and an LED. Wherein, the solar cell includes a plurality of cut solar cells, the solar cells are neatly arranged on one side of a PCB (printed circuit board), the control circuit is mounted on another PCB, and the above two The backs of the two PCB boards are bonded together with glue to form a lawn lamp control module that integrates solar cells and contr...

Problems solved by technology

In this patent, simply arranging a plurality of solar cells together without restricting the arrangement, then there must be the possibility of irregular arrangement, and this irregularity may be displayed to a greater extent in the The upper surfaces of the above-mentioned multiple solar cells are not on the same horizontal plane, so the solar cell panels in this form are not conducive to their installation in electronic devices such as mobile phones, and the market utilization rate is very low.

In addition, the patent does not disclose the connection method between the plurality of solar cells and the PCB board. In the prior art, a large-area welding process is often used to realize the connection between the solar cells and the PCB board. During the process, since the pads of the PCB board and the expansion coefficients of the solder paste are different, it is easy to cause the fragmentation of the solar cells

The most important thing is that in the prior art, when a plurality of solar cells are packaged on the PCB board, the electrode leads drawn from the main grid line of each solar cell and connected to the PCB board are all Single lead wire, for this kind of lead wire design, once the lead wire is damaged, it will cause the paralysis of the entire solar cell, resulting in the failure of the device to work normally
