Electronic Special Gases (ESG) are widely used in the photovoltaic cell industry, and these Special Gases play a key role in the manufacturing, processing and testing of solar cells. The following are some electronic special gas applications in the photovoltaic cell industry and their development trends:
1. Vapor deposition (CVD): ESG is commonly used in CVD processes to grow thin film materials in photovoltaic cells, such as amorphous silicon, hydrogenated amorphous silicon, or hydrogenated amorphous silicon telluride. By controlling the atmosphere and the gas precursor, a high-quality, uniform and dense thin film layer can be prepared, thereby improving the battery efficiency.
2. Atmosphere control: During the manufacturing and processing of photovoltaic cells, special gases are used to maintain specific atmosphere conditions, such as low-oxygen atmosphere, high-nitrogen atmosphere or other atmospheres, to control reaction conditions, reduce impurities and oxidation, and improve battery components Quality and performance.
Atmosphere monitoring: The atmosphere monitoring system is used to monitor the atmosphere conditions in the manufacturing process of photovoltaic cells in real time to ensure its stability and consistency. This helps to improve production efficiency and product quality.
4. Gas etching: ESG can be used to etch thin film materials in photovoltaic cells to make electrodes or reaction layers of cells. The etching process requires precise control of the atmosphere and reaction conditions to obtain the desired pattern and shape.
5. Gas sensor: During the production of photovoltaic cells, gas sensors are used to detect and monitor the gas composition and concentration in the atmosphere. These sensors help ensure the stability and safety of the production process.
With the continuous development of photovoltaic cell technology and the growth of solar power industry, the demand for electronic special gas is also increasing. Future trends may include higher purity, more stable special gas supply, and more intelligent atmosphere control and monitoring systems to support more efficient and reliable photovoltaic cell production and a more competitive solar power industry. In addition, with the introduction of new materials and new processes, the application field of electronic special gas may continue to expand and innovate.
