Title:
MANUFACTURING METHOD FOR SHINGLED ASSEMBLY AND SHINGLED ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2021/008634
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a shingled assembly, and a shingled assembly. The method comprises the following steps: arranging solar cell pieces and conductive pieces in a shingled manner on a top surface of a bottom encapsulation structure along a second direction to form a plurality of cell strings, such that the conductive pieces are positioned at back ends of the cell strings, and the cell strings being arranged along a first direction perpendicular to the second direction to form a cell piece array; providing a first bus bar and a second bus bar on a top side or a bottom side of he cell piece array, so as to cause the first bus bar to be in electrical contact with a main gate line of the solar cell piece at the front end of each cell string, and the second bus bar to be in electrical contact with the conductive piece of each cell string; and laminating a combined structure of a top encapsulation structure, the cell piece array, and the bottom encapsulation structure. The method provided in the present invention is able to combine arraying processing and shingling processing, directly shingling and arraying cell pieces on a bottom encapsulation material, and doing so is low-cost, high-efficiency, and easy to operate.
