specific Embodiment approach

[0062] Furthermore, please also refer to Figure 2 to Figure 3 , as a specific embodiment of the manufacturing method of the shingled assembly provided by the present invention, the end of the first solar battery sheet 21 is provided with a first groove 211 with an open outer surface; at the end of the first solar battery sheet 21 Laying the welding layer 22 includes:

[0063] The solder layer 22 is laid in the first groove 211 .

[0064] By arranging the soldering layer 22 in the first groove 211, the thickness of the first solar cell sheet 21, the soldering layer 22 and the second solar cell sheet 23 is reduced, and the first solar cell sheet is avoided during the lamination process. 21. The thickness of the laminated portion of the welding layer 22 and the second solar battery sheet 23 is too large, and the force is concentrated, causing the first solar battery sheet 21 or the second solar battery sheet 23 to break. It is also possible to increase the thickness of the wel...

Abstract

The invention provides a manufacturing method of a laminated tile assembly, and belongs to the field of photovoltaic power generation. The laminated tile assembly comprises a lower surface layer, a solar cell layer and an upper surface layer arranged in a laminated manner from bottom to top, the solar cell layer comprises a first solar cell, a second solar cell and a welding layer whose melting point is lower than the lamination temperature. The manufacturing method of the laminated tile assembly comprises that the first solar cell, the welding layer and the second solar cell are laid on the lower surface layer; the upper surface layer are laid on the first and second solar cells; and the laid lower surface, the solar cell layers and the upper surface layer are heated to the lamination temperature to carry out lamination, so that the welding layer is melted to weld the first and second solar cells. The welding layer is melted by heating in the lamination process, so that the first andsecond solar cells are welded, an independent welding step is omitted, technology is simplified, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and more specifically relates to a method for manufacturing a shingled module. Background technique [0002] The laminated module is a kind of high-efficiency module that is becoming popular in the photovoltaic industry at present. The laminated module connects the cut pieces of solar cells in an overlapping manner, and uses a small amount of welding ribbon at the edges of the two ends of the solar cell string or the back electrode. Welding is carried out, and then the bus bar is welded with the lead-out ribbon. Compared with conventional modules, this module closely arranges solar cells in a series-parallel structure, which reduces the internal loss caused by interconnecting the cells, and more than 13% of the cells can be placed in the same module area. sheet, increasing the conversion efficiency of the module. [0003] The complete production process of the current shin...
