2025 Company News
Cybrid Technologies streamlined its portfolio to two double-fluorine transparent products in 2025, reducing redundancy and aligning with the demand for 1,500 V systems in bifacial modules.

Jolywood launched a transparent backsheet with a black grid in 2025, reporting over 93% transmittance and less than 2% degradation after three years of field testing, demonstrating strong outdoor reliability.

Hangzhou First Applied Material emphasized its transparent BEC-301T and high-voltage BEF-402 backsheets in 2025, which achieve partial discharge levels above 1,600 VDC and water vapor transmission rates below 1.5 g/m2·24h, enabling stable operation in harsh climates.

Lucky Film Co., Ltd. continued to expand its transparent CPCt1 series, a dual-coating backsheet with 305 μm effective thickness and 1,500 V rating, targeting large-scale bifacial deployments.

Hubei Huitian New Materials introduced the transparent PV308C-T backsheet with WVTR ≤ 1.0 g/m2·day and TÜV-certified ≥ 1000 VDC partial discharge performance, supporting long-term anti-yellowing and rear-side reflectivity.

Market Trend
Transparent Backsheets as Dual-Glass Alternatives
In 2024-2025, transparent double-fluorine backsheets have proven to be lighter than dual-glass solutions, reducing module weight by nearly 30% and improving thermal management. This makes them especially attractive for floating PV projects and large ground stations where handling efficiency reduces balance-of-system costs.

Maturity of 1,500 V Standards
By 2025, nearly all premium double-fluorine backsheets meet or exceed 1,500 VDC partial-discharge requirements and ≥18 kV breakdown voltages. These standards match utility-grade module designs, supporting higher string voltages and cost-effective plant layouts.

Market Divergence: Coated vs. Film-Based Solutions
The market has split into two dominant routes: coated backsheets (CPC) and film-based backsheets (PVF, PVDF). Coated CPC variants gained significant share by 2024 as cost-effective solutions, while PVDF- and Tedlar-based film products remained preferred for environments with extreme UV or chemical exposure.

Verified Field Reliability
Field testing in 2025 confirmed that transparent fluorine backsheets maintain over 93% transparency with minimal degradation after three years, reinforcing their position as durable alternatives in bifacial modules and high-yield energy farms.

Policy and Tariff Uncertainty
U.S. trade actions in 2024-2025, including the expiration of anti-dumping duty moratoriums and new tariff regimes, have reshaped global supply chains. Manufacturers are increasingly diversifying sourcing strategies and regionalizing production to mitigate tariff impacts, particularly in North America and Southeast Asia.

High-Growth Applications
The strongest demand is coming from floating PV, agricultural photovoltaics, desert-based solar farms, and high-altitude projects. Double-fluorine backsheets' weather resistance, UV stability, and mechanical durability are crucial advantages in these challenging environments.

Innovation in Optics and Durability
New developments include black-grid transparent backsheets that combine transparency with reflective elements to enhance bifacial module output. Meanwhile, coatings with WVTR ≤ 2.0 g/m2·day and high dielectric thickness (>300 μm) are becoming the industry norm in 2025.

Conclusion
The Solar Double-Sided Fluorine Backsheet market in 2025 stands at a pivotal stage. With rapid adoption of transparent, lightweight, and high-voltage designs, coupled with shifting global trade policies, the sector is simultaneously challenged and accelerated. The 9.7% CAGR through 2031 reflects both robust technological innovation and strategic repositioning by leading manufacturers, while downstream adoption in bifacial modules ensures steady growth across floating, agricultural, and utility-scale solar installations worldwide.
