If your company wishes to sign a strategic agreement, we can discuss it in detail. We will give priority to the needs of strategic agreement customers, and "one customer, one line" will fix production lines for strategic customers, reserve sufficient production capacity and inventory, and ensure the needs of strategic customers who have paid in advance.

1) FFC fluorine coating and film integration;

2) Microwave curing technology;

3) Roll-to-roll plasma treatment and chemical grafting technology under normal temperature and pressure;

4) Integrated equipment innovation: A roll-to-roll one-stage back film production line was developed.

1) Use imported fluororesin from Daikin, Japan. This fluororesin product has more than thirty years of outdoor use data support.

2) Use highly hydrolysis-resistant PET.

3) High-quality materials are used both inside and outside, and the materials are well matched and balanced.

4) Jolywood's patented technology solves the problem of permanent bonding between fluorine and PET, and backsheet and EVA.

5) Have its own core technology and the ability to continuously reduce costs.

1) Using organic-inorganic nano-hybridization and molecular design interconnection penetration technology, we successfully developed fluorocarbon coating FFC (modified PTFE polymer), and created a unique process of directly forming a fluorine film on the PET surface to achieve an integrated film without gelling.

2) Use PLC cast tangent coating to realize the innovative application of microwave curing technology in the curing of back film fluorine coatings.

3) Plasma treatment and chemical grafting technology.

4) Integrated equipment innovation: A roll-to-roll backing film production line was developed.

As the packaging material on the back of the component, the backsheet plays an important role in protecting the component. For components that are outdoors for a long time, they have to withstand external damage such as hot and cold cycles, high temperature moisture, ultraviolet radiation, etc. Among many polymer materials, fluorine-containing materials are undoubtedly the most Excellent choice. Fluorocarbon resin material has the best weather resistance (reliability test). Its C-F bond energy is about 485KJ/mo. It is the material with the largest bond energy among all polymer materials. It has the best resistance to the outside world and has excellent aging resistance.

FFC is coated backplane, CPC structure. Our company is the earliest and largest manufacturer of coated backsheets in the world. Our company has been building the factory in 2018, and our products have been tested outdoors for 10 years. Advantage: Fluorine-containing on both sides, reliable UV resistance The fluorine coating has excellent bonding performance with PET and does not delaminate after aging. The inner fluorine coating is thick enough to effectively block UV rays and protect PET The thermal stability of the inner fluorine coating is better than that of E film PET hydrolysis resistance grade (PCT) ≥48H, stable mechanical properties

Currently,Shanxi Jolywood Solar Cell Technology has completed the first phase of the 16GW high-efficiency TOPCon cell intelligent factory project, with 8GW in production. The second phase of 8GW equipment installation and debugging is underway, with plans to achieve full production by 2024, accelerating the release of the company's high-efficiency battery production capacity and realizing the effects of scale production. We are improving cell conversion efficiency through the introduction of SE technology, optimization of front and back grid lines, and the latest laser-assisted sintering technology. Currently, the average cell conversion efficiency can reach over 26%.
