1. Photovoltaic field
In the photovoltaic industry, PECVD coating technology is widely used in the manufacturing process of solar cells. Its main effects include:
Improving photoelectric conversion efficiency: PECVD coating can form a high-quality anti reflection film, greatly reducing the reflection loss of light on the silicon surface (according to calculations, the reflection loss rate of light on the silicon surface is as high as about 35%), thereby improving the utilization rate of solar energy by the battery cells and thus improving the photoelectric conversion efficiency.
Surface passivation effect: The hydrogen ions in PECVD coating have a good passivation effect on the surface of the battery cell, which can reduce the surface recombination rate of the emitter junction, reduce the dark current, and thus improve the open circuit voltage and photoelectric conversion efficiency.
Technological advantages: PECVD coating technology adopts a low-temperature process, effectively reducing production costs, and the generated thin film has high quality, greatly improving the performance of battery cells.

2. In the field of electronic products
In the field of electronic products, PECVD coating technology has also shown good advantages:
Strong customizability: By adjusting plasma parameters, films with different properties such as waterproof, hydrophobic, anti-corrosion, salt fog resistance, aging resistance, and bacteria resistance can be customized to fully meet the diversified protection needs of various parts of the product.
Good uniformity: PECVD coating can form a uniform film in various parts, ensuring the overall protective effect of the product.
Strong adhesion: Through plasma treatment, the film layer is tightly bonded to the substrate, improving the waterproof, dustproof, anti-corrosion and other capabilities, making the product more durable and reliable.
Ultra thin film layer: PECVD coating technology can form an ultra-thin film layer, which has no impact on the electrical conductivity, heat dissipation, and signal transmission of the product.
Environmentally friendly and efficient: PECVD coating adopts vacuum and dry processes, which are pollution-free and have high production efficiency, which can significantly reduce unit product costs.

3. Other application areas
In addition to the fields of photovoltaics and electronic products, PECVD coating technology is also widely used in fields such as mobile phones, sports equipment, medical supplies, military industry, and special accessories. In these fields, PECVD coating also exhibits excellent protective effects, such as preventing dust infiltration, enhancing hydrophobicity, and improving material surface hardness.
