Shanghai Huitian New Material Co., Ltd Latest company case about PV308C-T solar cell backsheet introductions

      PV308C-T solar cell backsheet offers several advantages due to its unique structural parameters and performance characteristics. Here are some key advantages of the PV308C-T solar cell backsheet:

      Enhanced Weather Resistance: The PV308C-T backsheet features two highly transparent fluorocarbon coating layers as the weather-resistant layer. This design provides excellent protection against environmental factors such as moisture, UV radiation, and temperature variations. It ensures the long-term durability and reliability of the photovoltaic modules, even in harsh weather conditions.
     Superior Mechanical Strength: The backsheet's biaxially oriented high barrier polyester film substrate, with a thickness of 300±30 μm, offers exceptional mechanical strength. It provides robust support to the solar cells and protects them from physical damage, such as impact or bending forces. The backsheet's tensile strength of ≥ 110 MPa in the machine direction (MD) and ≥ 100 MPa in the transverse direction (TD) further reinforces its mechanical integrity.
      Excellent Adhesion: PV308C-T backsheet demonstrates outstanding bonding strength with commercially available packaging materials. This characteristic ensures a secure and reliable lamination process during module assembly. The excellent adhesion properties prevent delamination or separation of layers, enhancing the overall module performance and longevity.
        Long Service Life: The PV308C-T backsheet is designed to provide a service life of more than 25 years for photovoltaic modules. Its exceptional resistance to aging and weathering ensures long-term stability and reliability in solar energy systems. The backsheet's resistance to heat shrinkage, with a rate of ≤ 1.5% in the MD and ≤ 1.0% in the TD, further contributes to its extended lifespan.
Effective Electrical Insulation: With a volume resistivity of ≥ 1.0*10^13 Ω·cm, the PV308C-T backsheet offers excellent electrical insulation properties. It prevents electrical leakage and ensures the safe and efficient operation of the photovoltaic modules. The backsheet's breakdown voltage of ≥ 16 kV adds another layer of protection against electrical faults.
      High Optical Transmittance: The PV308C-T backsheet exhibits high optical transmittance of ≥ 85% in the wavelength range of 400-1100 nm. This characteristic allows maximum sunlight penetration into the solar cells, optimizing the overall energy conversion efficiency of the module. The transparent nature of the backsheet also enhances the aesthetics of the solar panels.
Compliance with Industry Standards: The PV308C-T backsheet complies with various industry standards, such as GB/T (Chinese National Standards) and IEC (International Electrotechnical Commission) standards. This compliance ensures that the product meets quality and performance requirements, providing reassurance to manufacturers and end-users alike.
      In summary, the PV308C-T solar cell backsheet offers significant advantages for photovoltaic module packaging. Its enhanced weather resistance, superior mechanical strength, excellent adhesion properties, long service life, effective electrical insulation, high optical transmittance, and compliance with industry standards make it a reliable and high-performance solution for solar energy applications.
