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 battery sheet 24 is greater than the thickness of the edge coating film 23 of the solar battery sheet 24 .

[0032] Specifically, there is an edge coating 23 in the coated solar cell 24, the edge coating 23 can be laser scribed and cut by a laser scanning system, and the edge coating 23 of the solar cell 24 is cut deeper than the edge of the solar cell 24. The thickness of the coating f...

Abstract

The invention relates to an edge processing system and method, in particular to an edge processing system and method for solar cells. According to the technical solution provided by the present invention, the edge processing system of the solar cells includes at least one processing flow channel and a laser scanning system for laser scribing and cutting, and transmits the coated solar energy on the laser processing table of the processing flow channel. After the battery sheet, the laser scanning system can be used to carry out laser scribing and cutting on the edge coating of the solar cell, and the cutting depth of the scribing line on the edge coating of the solar cell is greater than the thickness of the edge coating of the solar cell. The invention can effectively solve the problem of efficiency loss caused by winding plating during the coating process by performing laser scribing and cutting on the edge coating of the solar cell, improve production efficiency and automation, and is safe and reliable.

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...
