Manufacturing method of laminated tile assembly

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...
