Nitrogen Generator For Photovoltaic Supplier

What is the overall application process of nitrogen generator in solar panel production?

In the production process of solar panels, nitrogen generators play an indispensable role. The nitrogen it provides is not only used to protect the production environment, but also ensures the smooth progress of the production process and the high-quality performance of the final product.

The production of solar panels requires a clean, oxygen-free environment starting from the inspection of silicon wafers. As the basic material of solar panels, the quality of silicon wafers directly affects the conversion efficiency of the battery. In the silicon wafer inspection link, the nitrogen provided by the nitrogen generator is used to protect the silicon wafer from impurities and moisture in the air to ensure the accuracy of the inspection.

Next is the surface texturing link. A special velvet structure needs to be formed on the surface of the silicon wafer to increase the absorption and conversion efficiency of light. In this process, the nitrogen provided by the nitrogen generator not only ensures the cleanliness of the working environment, but also avoids the influence of oxidation on the quality of the velvet.

Diffusion junction is a key step in the production of solar panels, which determines the photoelectric conversion performance of the battery. In this process, the nitrogen generator once again plays an important role. Nitrogen, as a carrier gas, brings the diffusion source into the reaction zone and reacts with the silicon wafer to form a PN junction. At the same time, nitrogen also prevents oxidation reactions during the diffusion process and ensures the quality of the PN junction.

As the production process progresses, nitrogen generators play an important role in multiple links. In the steps of dephosphorized silicon glass, plasma etching, and anti-reflection film coating, nitrogen is used to protect the surface of the material to prevent oxidation and contamination.

In the screen printing and rapid sintering links, nitrogen has become an indispensable guarantee. In the screen printing process, nitrogen can prevent the ink from drying and clogging the screen; in the rapid sintering process, nitrogen ensures the stability of the material at high temperatures and prevents oxidation and impurity generation.

Nitrogen generators play the role of "guardians" in the production process of solar panels. The nitrogen it provides not only ensures the cleanliness and stability of the production environment, but also ensures the smooth progress of the production process and the high-quality performance of the final product. With the continuous development of solar panel technology, the role of nitrogen generators will become more and more important.
