Photovoltaic glassine, also known as solar cell backsheet paper, is a specialized type of paper used as the backing in solar panels. It is typically made from a mixture of glass fibers, pulp, and resin, offering high compressive strength and dimensional stability.

Photovoltaic glass is primarily used in the manufacturing process of solar panels, serving as the base material for the backsheet. Since the backsheet of solar panels must possess certain physical and chemical properties to maintain durability and stability in complex environments like high temperatures, humidity, and pressure, it is also required to provide certain reflective and insulating functions due to the transparency and light absorption of the solar panels, thereby enhancing the power generation efficiency and stability of the cells.

Therefore, photovoltaic glass paper requires high physical and chemical properties, including high tensile strength, compressive strength, and temperature resistance. During the production process, the photovoltaic glass paper must also undergo special coating processing to provide certain reflective and insulating functions, while ensuring the adhesion of the paper surface and its contact with other materials.

In summary, photovoltaic glassine is a specialized paper with high-performance requirements, used in the manufacturing and production process of solar panels, playing a crucial role in the performance and stability of the solar panels.
