Lightweight photovoltaic transparent front plate encapsulated components Currently, the front plate materials of lightweight photovoltaic modules on the market mainly include soft glass, ETFE (ethylene-tetrafluoroethylene copolymer), PVDF materials, etc.

Currently, the photovoltaic solar module industry is undergoing a transition period from PERC technology to N-type technology. N-type cells represented by TOPcon have begun to enter the mass production stage of explosive growth. This transformation has put forward higher requirements for the performance of the encapsulation film of photovoltaic modules. Photovoltaic film encapsulation materials are used between the solar glass/backsheet and solar cells. Their main function is to protect the solar cells, ensure that the photovoltaic modules are not affected by the external environment during operation, and extend the service life of the modules.

In the PV solar panels production, one important process is the backsheet frame sealing and the junction box sealing. We always used the good performance silicone sealant for PV modules encapsulation. If this work not done well, what will be impact ?

POE has good elasticity, strength, aging resistance, weather resistance, and water-proof properties. Its traditional application areas are mainly in automotive parts. Photovoltaic-grade POE is mainly used for photovoltaic components, especially in the packaging of TOPCon, HJT, and perovskite.

Photovoltaic (PV) adhesives utilize moisture in the air to cure at room temperature to provide excellent bonding and sealing properties for solar PV module outer frame and junction box applications. When manufacturing and assembling PV modules, it is necessary to select adhesives with excellent properties such as high light transmission, weatherability, and high adhesion to ensure the quality and long-term stability of PV modules. The importance of adhesives in PV modules is mainly reflected in the following aspects:

Photovoltaic glass plays an important role as the special glass for the cover plate of solar cells It not only protects the solar panel from oxidation and corrosion by external moisture and gas, but also ensures that the components are not subjected to external forces The core performance of photovoltaic glass lies in its high transmittance, high strength and strong corrosion resistance These characteristics directly affect the life and power generation efficiency of photovoltaic modules.

In recent years, with the continuous advancement of photovoltaic technology and the enhancement of environmental awareness, photovoltaic power generation, as a clean and solar renewable energy, is gradually attracting global attention.

According to the "Global PV Market Outlook for the first Quarter of 2024" report released by PV-Tech, the global PV installed capacity will increase from about 444GWdc in 2023 to 655GWdc this year. China will continue to dominate the installed capacity in 2024 (313.7GWdc), accounting for 54.7% of the new global PV capacity installed this year. It was followed by the United States (40.6GWdc), India (18.1GWdc), Brazil (17GWdc) and Germany (16.5GWdc).

At present, BIPV technology has been widely used, especially in public buildings, commercial buildings and residential buildings. By combining photovoltaic building materials products with building roofs, walls and other structures, BIPV technology achieves building self-sufficiency, reduces carbon emissions, and improves energy efficiency.

Photovoltaic glass, as a special glass for solar cell covers, plays a vital role. It not only protects solar panels from oxidation and corrosion from external moisture and gas, but also protects components from damage by external forces. The core properties of photovoltaic glass lie in its high light transmittance, high strength and strong corrosion resistance. These characteristics directly affect the lifespan and power generation efficiency of photovoltaic modules.
