Description

Technical Field

[0001] The invention relates to the field of amorphous silicon solar cells, and in particular to an amorphous silicon solar cell production process and a finished product automatic detection device. Background Art

[0002] On the one hand, the production process of amorphous silicon solar cells in the prior art is ITO conductive glass etching - cleaning machine cleaning - preheating - coating - laser film engraving - printing conductive ink - primary baking - printing protective layer - secondary baking - printing LOGO - tertiary baking - printing welding points - quaternary baking - cutting glass - splitting - testing - packaging; the above process has the following defects in the actual production process:

[0003] ① The traditional ITO conductive glass etching process is completed by chemical acid and alkali corrosion and neutralization reaction. Later, due to environmental protection and pollution requirements, manufacturers abandoned this practice and switched to laser engraving. However, this method uses linear motion of the platform, so it can only engrave straight lines, and the efficiency is limited by the platform movement speed, which limits the variety of products and production speed.

[0004] ② The cleaning process of traditional cleaning machines requires the addition of cleaning agents, which pollutes the environment.

[0005] ③ During coating, various mixed gases such as P-type and N-type will be introduced into the vacuum chamber. The traditional process is to directly introduce various mixed gases into the vacuum chamber to allow them to mix naturally, but the uniformity of the gas mixing cannot be guaranteed, resulting in uneven product film layers, which ultimately affects the electrical performance of the product.

[0006] Therefore, it is necessary to solve the above three problems.

[0007] On the other hand, when inspecting the solar cells made by the above process, an infrared camera is used. When the diodes in the solar cells are powered on, they generate heat and emit infrared light. The infrared camera can detect the heat distribution on the surface of the solar cell and transmit the image to the terminal, which can detect the internal defects of the solar cell. However, the infrared camera in the traditional technology has the defect of being difficult to disassemble and install, and requires a large number of tools, which brings trouble to the entire disassembly and maintenance work; and during the disassembly and installation process, the infrared camera is easy to fall directly to the ground under gravity and cause damage.

[0008] Therefore, it is necessary to optimize the disassembly and installation structure of the infrared camera to facilitate regular maintenance; at the same time, it is also necessary to prevent the infrared camera from falling to the ground during the disassembly and installation process.
