Problems solved by technology

Since thimble welding is a contact process, improper contact pressure is likely to form residual concentrated stress in the stressed area of ​​the battery module. If the contact pressure is improper, it is easy to cause micro cracks in the solar cell, which increases the subsequent movement and packaging material lamination process. Fragmentation rate of lamination process or mechanical loading test

Embodiment Construction

[0032] The following will clearly illustrate the spirit of the present invention with the accompanying drawings and detailed descriptions. After any person of ordinary skill in the art understands the preferred embodiments of the present invention, they can be changed and modified by the technology inspired by the present invention. depart from the spirit and scope of the present invention.

[0033] refer to figure 2 , which shows a perspective view of an embodiment of the solar module of the present invention before welding. The solar module 200 includes a plurality of solar cells (solar cells) 210 and a ribbon (ribbon) 220 for connecting the plurality of solar cells 210 . The solar cells can be configured in columns or rows, for example, and the solder ribbon 220 can be electrically connected to a junction box (not shown in the figure) arranged on the back panel to communicate with the solar cells 210 and the junction box, so as to control the solar cells. 210 and transmi...

Abstract

The invention provides a solder strip. A section of the solder strip perpendicular to a longitudinal axis is in an arc shape. A solar module includes a plurality of solar batteries. The solar batteries in the solar module are connected through the solder strips. The invention also provides a method for connecting the solder strip and the solar batteries. In the method, the solder strips are disposed on the solar batteries, wherein parts of the solder strips are on the solar batteries while parts of the solder strips protrude out of the solar batteries. And the parts of the solder strips on the solar batteries are welded. The technical scheme in the invention can reduce the generation of micro cracks of the solar batteries in a welding and processing technique.

Description

technical field [0001] The invention relates to a solar module, in particular to a solar module welding strip. Background technique [0002] The increasing scarcity of non-renewable energy sources such as coal, oil, and uranium, and the associated ecological and safety concerns, make it critical to increase the use of alternative, non-consumable energy resources. The adoption of solar energy has been facilitated by improved manufacturing techniques for the mass production of solar panels. Solar power can achieve significant environmental benefits. [0003] A solar module mainly includes a solar cell, a packaging material, a back sheet, and a frame for fixing the solar cell and the back sheet therein. Solar modules generally use ribbons to connect individual solar cells. [0004] However, if figure 1 As shown, generally, the thimble 110 is used to pressurize the soldering ribbon 120 to the solar cell 100 , and then the soldering ribbon 120 is welded to the solar cell 100 ...
