Embodiment Construction

[0030] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0031] Such as figure 1 and Figure 4 As shown: In order to effectively solve the problem of efficiency loss caused by winding plating in the coating process and improve production efficiency and automation, the present invention provides a laser scanning system, and uses the laser scanning system to perform laser scanning on the edge coating 23 of the solar cell 24 after coating. Scribing and cutting, and the scribing and cutting depth of the edge coating film 23 of the solar cell sheet 24 is greater than the thickness of the edge coating film 23 of the solar cell sheet 24 .

[0032] Specifically, there is an edge coating 23 in the coated solar battery sheet 24, and the edge coating 23 can be laser scribed and cut by a laser scanning system, and the cutting depth of the edge coating 23 of the solar battery sheet 24 is greater than that of the edge of the sola...

Abstract

The invention relates to an edge processing system and method, in particular to an edge processing system and method of a solar cell. According to the technical scheme provided by the invention, the edge processing system of the solar cell comprises at least one processing flow channel and a laser scanning system used for laser scribing and cutting, and after the coated solar cell is conveyed on alaser processing table of the processing flow channel, the laser scanning system is employed for laser scribing and cutting on the edge coating film of the solar cell, wherein the scribing and cutting depth of the edge coating film of the solar cell is greater than the thickness of the edge coating film of the solar cell. Laser scribing and cutting are carried out on edge coating of the solar cell, the problem of efficiency loss caused by winding plating in the coating process can be effectively solved, the production efficiency and the automation degree are improved, and the safety and reliability are achieved.

Description

technical field [0001] The invention relates to an edge processing system and method, in particular to an edge processing system and method for solar cells. Background technique [0002] Since the global oil crisis broke out in the 1970s, solar photovoltaic power generation technology has attracted great attention in western developed countries. From the perspective of environmental protection and energy sustainable development strategies, governments of various countries have formulated policies to encourage and support solar photovoltaic power generation technology. The photovoltaic industry is developing rapidly around the world. In addition to crystalline silicon solar cells and amorphous silicon solar cells, various compound semiconductor solar cells and new solar cells such as stacked solar cells composed of two types of solar cells have emerged. Because of its cleanliness and renewable nature, solar energy has become one of the best alternatives to traditional energy...
