Imbricated assembly and manufacturing method thereof

Abstract

The invention relates to an imbricated assembly and a manufacturing method thereof. The top surface and / or the bottom surface of each solar cell in the imbricated assembly are / is provided with: a plurality of auxiliary grid lines, wherein each auxiliary grid line extends along a first direction; imbricated conductive structures, wherein the imbricated conductive structures located on the top surfaces and the imbricated conductive structures located on the bottom surfaces are located at the two end portions of the solar cell pieces in a second direction respectively, and the imbricated conductive structures are configured in the mode that when the multiple solar cell pieces are arranged in the imbricated mode, the adjacent solar cells are conductively connected through an imbricated conductive structure; and a plurality of conductive strips, wherein each conductive strip is in contact with the plurality of auxiliary grid lines and the imbricated conductive structure. According to the solar cells in the imbricate assembly, efficiency loss caused by slicing of the cells can be avoided or reduced, and the problems that the auxiliary grid lines are too long and the transmission capacity is insufficient can also be avoided.

Description

Technical field[0001]The present invention relates to the field of energy, and more particularly to a superimposed tile assembly and a method of fabricating thereof.Background technique[0002]The climate is one of the important factors in the human living environment, and it is also an important resource for human production. With the expansion of human survival activities, human activities have also have an increasingly impact on climate change. As the fossil energy is exhausted, there is a climate impact, especially the greenhouse gas discharges to globally sustainable and healthy development.[0003]With global coal, petroleum, natural gas consumption, the ecological environment is deteriorating, especially greenhouse gas emissions, leading to increasingly severe global climate changes, and sustainable development of human society has been seriously threatened. All countries in the world have developed their own energy development strategies to address the limited nature of routine ...

Problems solved by technology

[0005] The current shingling process mainly has the following methods: the large battery sheet is cut into small pieces multiple times, and each small piece is shingled to form a shingled module. The number of cutting knives for the battery sheet is large, and the cutting loss is large, which affects the overall module. Power and efficiency; a large battery sheet is only cut once to form a half-sheet structure, and the half-sheet structure is shingled into a shingled module, but such a process has the disadvantages of too long transmission distance of the carrier sub-grid in the battery sheet or vertical current collection of the printed silver paste main grid Problems such as poor collection and transmission capabilities
