Low Temperature Photovoltaic PET Ink

When the photovoltaic backplane has to resist salt corrosion in the hot and humid sea breeze at 80℃, and when the PET film has to withstand ten years of ultraviolet exposure but cannot be deformed, the reflection attenuation and substrate damage of traditional solvent based ink are devouring the benefits of power stations. This Low Temperature Photovoltaic Ink redefines the performance limit of the flexible backplane with bionic optical structure and low-temperature intelligent manufacturing technology.

Three Technological Revolutions —— Hard-core Strength Penetrating the 25-year Warranty Period

Low temperature curing "light energy matrix"-unlocking 93% reflectivity at 80℃

Subversive technology:

Low temperature curing at 120-150℃ (traditional process needs more than 200℃)

The thermal shrinkage of PET substrate is less than 0.05% (the industry average is more than 0.3%).

Optical breakthrough:

The reflective layer with bionic honeycomb structure has an ultraviolet-visible light reflectivity of 92.5%.

The transmittance in infrared band is increased by 15%, and the working temperature of the module is reduced by 8-12℃

Salt spray nemesis-"titanium armor" of coastline

Extreme test data:

After 5000 hours of salt spray test (ASTM B117), the reflectance attenuation is less than 0.8%.

After soaking in 5% saline for 30 days, the adhesion retention rate was > 99%.

Self-repairing black technology:

Microencapsulated silane is automatically released in case of moisture, and microcracks below 3μm can be repaired.

Electrolytic corrosion current < 0.2 μ a/cm (IEC 62716 standard).

The King of Boiling Performance —— The "Ultimate Survivor" in Hot and Humid Environment

Double 85 strengthening test (85℃/85%RH):

After 3000 hours, the yellowing index Δ b < 1.0 (invisible to the naked eye).

Adhesion after boiling test (100℃/48h) ≥4B(ASTM D3359).

Actual combat case:

A floating power station in Southeast Asia experienced the rainy season erosion, and the annual attenuation of the backplane reflectivity was only 0.2%.

Industry 4.0 intelligent adaptation-the "invisible pusher" of mass production accuracy
