Embodiment Construction

[0020] Below in conjunction with accompanying drawing and specific embodiment, further illustrate the present invention, should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various aspects of the present invention Modifications in equivalent forms all fall within the scope defined by the appended claims of this application.

[0021] Such as figure 1 and figure 2 As shown, the manufacturing method of the back contact solar cell string comprises the following steps:

[0022] (1) Utilize automatic gluing machine to spray conductive glue on the busbar line of the back contact solar cell 4 backside;

[0023] (2) Prepare series template 2: The series template is an aluminum alloy or stainless steel plate with a series of grooves on it. The depth of the grooves is equivalent to the thickness of t...

Abstract

The invention discloses a back-contact solar battery string, which comprises a plurality of back-contact solar cells, solidified conductive glue and a metal soldering belt, wherein the back-contact solar cells are arranged in a linear way at intervals, and the back surfaces of the back-contact solar cells are adhered with the metal soldering belt through the solidified conductive glue. The invention also discloses a production method of the back-contact solar battery string. Due to the adoption of the back-contact solar battery string and the production method thereof, the adhering and solidification problem of the back-contact solar cells and the soldering belt can be solved, and the situation that the solar cells and the soldering belt shift before the conductive glue is solidified to influence the performance of the back-contact solar battery string is prevented.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a back-contact solar cell string and a manufacturing method thereof. Background technique [0002] The production process of conventional solar cell modules mainly includes: single welding, series welding, lamination, lamination, frame mounting, etc. The production process of new back-contact solar cell modules mainly includes: gluing, series connection, curing, lamination, lamination , framing, etc. From the perspective of the production process, the difference between the two mainly lies in the steps before lamination. This is because the former adopts the welding method, and the latter adopts the method of conductive adhesive bonding. Compared with traditional welding, the bonding temperature is low, which can reduce the fragmentation rate; The light-receiving side of the back-contact module has no solder strips, main grid lines and sub-grid lines, so the area covered by ...
