What makes this dual‑coated nano‑layer on photovoltaic glass both more transparent and more wear‑resistant?

Sysmyk ^® A specialized ultra‑hard, anti‑reflection, light‑enhancing nano‑coating for photovoltaic glass, providing material‑level support for complex outdoor environments.
During the long-term operation of photovoltaic modules, the glass surface is exposed to more than just sunlight.

Windblown sand, dust, rain, temperature fluctuations, and routine cleaning and maintenance all continuously impact the photovoltaic glass on the module’s outermost layer. Particularly in environments characterized by high wind‑blown sand, heavy dust, and frequent cleaning, the photovoltaic glass must not only maintain high light transmittance but also withstand prolonged wear and tear.

For photovoltaic modules, light transmittance determines how much light can enter the module, while abrasion resistance dictates how long this optical performance can be maintained.

In response to this application requirement, Guangzhou Xisenmeike has launched:

Sysmyk ^® Ultra-High Hardness Anti-Reflection and Light-Transmission Nano-Coating (Dual-Coated) for Photovoltaic Glass

Product Code:
ZCP0082-R-SH-AR-D-B (Primer)
ZCP0083-R-SH-AR-D-T (Topcoat)

This is a dual‑coating nano‑coating solution for the surface of photovoltaic glass, featuring both a primer and a topcoat. It is ideally suited for photovoltaic glass applications that demand enhanced light transmittance, superior abrasion resistance, excellent resistance to sand and dust, and frequent cleaning and maintenance.

01 Why isn’t photovoltaic glass just “transparent”?
When sunlight strikes the surface of a photovoltaic module, some of the light is lost due to reflection from the glass surface.

Therefore, reducing reflectance and enhancing transmittance are key objectives in the surface functionalization of photovoltaic glass. However, in practical applications, photovoltaic glass must also withstand prolonged exposure to sand and dust erosion, cleaning-induced abrasion, and fluctuating outdoor environmental conditions.

If a coating merely “appears transparent” in the early stages but cannot withstand prolonged use and routine cleaning and maintenance, its optical advantages will be difficult to sustain.

Therefore, a photovoltaic glass coating suitable for complex environments must simultaneously address two challenges:

—Allow more light to enter the module
—Keep the light-transmitting advantage for longer

Sysmyk ^® This dual‑coated, ultra‑hard, anti‑reflection and high‑transmittance nano‑coating was specifically designed with these two objectives in mind.

02 Dual-coating design, balancing anti-reflection and wear resistance.
Unlike single-layer coating solutions, this product employs a dual-coat structure consisting of a primer layer and a topcoat.

Simply put, the primer primarily helps form a stable base coating layer, enhancing coating uniformity and interlayer adhesion; the topcoat further optimizes surface performance, balancing anti-reflective and transmissive properties with hardness and wear resistance.

By synergistically tuning the refractive index and nanostructure of a dual-layer coating—comprising a primer and a topcoat—the coating can form a transparent, uniform, and dense composite ultrathin film on the surface of photovoltaic glass.

Following pre-drying and tempering curing, the coating forms a stable inorganic crosslinked network that reduces surface reflectance while enhancing surface abrasion resistance and long-term optical stability.

In short, its core value can be summed up in one sentence:

It not only makes the glass more transparent, but also ensures that this light-transmitting performance is more stable and longer-lasting.

03 The typical transmittance gain can reach 2.3%–2.4%.
For photovoltaic glass products, improved light transmittance remains the most straightforward performance indicator.

Sysmyk ^® Dual‑coated ultra‑hard anti‑reflection and high‑transmittance nano‑coating, leveraging the synergistic effect of a primer layer and a topcoat to reduce surface reflection on glass, with a typical transmittance gain of 2.3%–2.4%.

For example, when the base glass has a visible light transmittance of 92.1%, after double‑coating, the effective solar transmittance can be increased to approximately 94.4%–94.5%.

This means that, without altering the component’s core structure, optimizing the glass‑surface material can help increase the amount of effective incident light reaching the module.

Of course, the actual light transmittance performance is influenced by factors such as the glass substrate, coating equipment, the compatibility of the primer and topcoat, the tempering process, and testing conditions. Prior to formal project implementation, it is recommended to verify the final results through sample testing and analysis of the light transmittance curve.

04 Not just anti-reflection—more importantly, real “hard power” is needed.
Photovoltaic glass is exposed to the outdoors for extended periods; its coating must not only deliver initial performance gains but also withstand the rigors of windblown sand, dust, and repeated cleaning.

Sysmyk ^® After tempering and curing, this dual‑coating finish achieves a pencil hardness of 7H.

This is also one of the key features that distinguish it from ordinary anti-reflective coatings.

Its typical performance characteristics include:

—Light transmittance gain of 2.3%–2.4%
—Pencil hardness 7H
—Adhesion Grade 0
—Change value after 48 hours of the PCT test ≤0.2
—The double-coated film layer is smooth, even, and transparent.

Behind these metrics lies the actual demand for photovoltaic glass in real-world applications:

It must balance high light transmittance with excellent wear and weather resistance; it should deliver outstanding initial performance while maintaining that performance over the long term.

For environments characterized by high wind‑blown sand, heavy dust, and frequent cleaning and maintenance, this stability is particularly critical.

05 What application scenarios is it suitable for?
Sysmyk ^® A specialized ultra‑hard, anti‑reflection, light‑enhancing nano‑coating for photovoltaic glass, primarily designed for PV glass products that demand superior antireflection performance and enhanced surface abrasion resistance.

For glass manufacturers, it helps enhance product differentiation and competitiveness.
For module manufacturers, it helps optimize the optical input of modules at the material level.
For complex outdoor application scenarios, it signifies a more stable and durable photovoltaic glass surface solution.

06 From high transparency to high hardness, the surface functions of photovoltaic glass are undergoing continuous upgrades.
Efficiency improvements in the photovoltaic industry are entering an increasingly refined phase.

In the past, our focus was primarily on cell efficiency, module encapsulation, and system design; today, functionalizing glass surfaces is also emerging as a key avenue for material‑level innovation.

For photovoltaic glass, anti-reflective and light‑transmitting coatings address the challenge of maximizing light ingress into the module; meanwhile, in harsh environments characterized by high wind‑blown sand, heavy dust, and frequent cleaning, ultra‑high hardness and excellent wear resistance determine whether the coating can withstand long‑term service.

Sysmyk ^® A specialized ultra‑hard, anti‑reflection, and light‑enhancing nano‑coating for photovoltaic glass, featuring a synergistic dual‑layer design of primer and topcoat. While boosting light transmittance, it further enhances coating hardness, wear resistance, and adaptability to harsh environmental conditions, delivering a more stable surface‑functionalization solution for photovoltaic glass.

Allow more light to enter the module,
It also makes the glass surface more durable over the long term.

This is precisely the key direction for upgrading photovoltaic glass—from “high transmittance” to “high hardness and durability.”
