Problems solved by technology

CIGS thin film solar cells will go through 3 scribing procedures in the manufacturing process, including laser scribing and mechanical scribing, but there may be changes in the line width or line spacing of the scribing lines, twisted scribing lines, insufficient scribing depth or cracking Wait for the bad phenomenon
The traditional sampling off-line inspection can no longer meet the current mass production needs, and an online full inspection system that can be combined with production line manufacturing is urgently needed. Therefore, an optical imaging device and inspection system is invented as an online full inspection system in the CIGS thin film solar cell processing process. Automatic optical inspection system is very necessary

Embodiment Construction

[0023] The present invention will be further described below in conjunction with specific examples.

[0024] The present invention will be described in detail below in conjunction with specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention. The application principle of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Early solar energy development was dominated by monocrystalline silicon, and later expanded to polycrystalline silicon, amorphous silicon, compound semiconductors and other materials. Thin-film solar cells are considered to have great development potential because they can save a large amount of raw materials and have flexible characteristics...

Abstract

The invention discloses a detection system. The system comprises an array type optical image capturing device, an image processing and detecting device, a positioning linear sliding table device, an image data backup device, a human-computer interface device and the like. The system is suitable for online automatic optical testing of the CIGS thin-film solar panel; after P3 mechanical scribing, aseries of subsequent steps are carried out, and digital processing can be carried out on each solar panel on a production line, so relevant detection and analysis can be rapidly and accurately completed, the total operation time can be controlled within 60 seconds, the detection speed requirement of a production line is completely met, the number of secondary products and defective products is reduced, and the manufacturing percent of pass is greatly increased.

Description

technical field [0001] The invention relates to the detection field, and more specifically relates to a detection system applied to CIGS thin-film solar cells. Background technique [0002] With the development of economy and society, people's demand for energy is also increasing day by day. Due to the limited reserves of conventional fossil energy such as coal, oil and natural gas, and the use of a large amount of greenhouse gases in the process of polluting the environment, the development and utilization of new clean energy is a must. Become the main way to solve conventional energy shortage and environmental pollution. [0003] As we all know, solar energy is an inexhaustible clean energy. In the current and future development process, solar energy is one of the most important and indispensable key energy sources. Since solar energy is inexhaustible, clean and pollution-free, it is the most ideal and sustainable renewable energy in the future. The use of solar energy c...
