JinkoSolar × Hysense Mec: Jointly Developing a Self-Cleaning and Light-Transmitting Coating for Photovoltaic Modules, Ushering in a New Generation of Power Generation Efficiency Revolution

Aug 05,2025

As the global “dual-carbon” strategy continues to deepen, the photovoltaic industry is entering a critical transition phase—from focusing on cost reduction to emphasizing efficiency improvement and performance enhancement. Advances in materials science are increasingly becoming the core driving force behind the next-generation upgrade of photovoltaic components.
In June 2025, at the 17th International Solar Photovoltaic Conference & Exhibition (SNEC), JA Solar Technology and Guangzhou Hishen Meike New Materials Technology Co., Ltd. officially signed the “Joint Development Agreement for Self-Cleaning and Light-Transmission Coating for Photovoltaic Modules.” An authoritative institution also certified the world’s first certification for self-cleaning photovoltaic modules. This cross-sector strategic collaboration marks the beginning of large-scale application of high-performance functional coatings in photovoltaic module systems, ushering in a new round of efficiency revolution.

01 Focusing on industry pain points, achieving systematic breakthroughs in self-cleaning and light-transmitting technologies.
During actual operation, photovoltaic modules often face issues such as dust accumulation, residual water stains, and electrostatic adsorption, which lead to reduced light transmittance, increased risk of hot spots, and ultimately affect the power plant’s generation efficiency and operation & maintenance costs.
In this collaboration between JA Solar and Hysen Mec, the focus will be on in-depth joint research centered around a “photovoltaic-specific self-cleaning + light-transmitting nano-coating system,” with a commitment to achieving systemic breakthroughs in the following three key areas:
1. Enhance optical transmittance: By adopting a multi-layer anti-reflection and light-transmitting structural design and optimizing the refractive indices at interfaces, we maximize the efficiency of sunlight incidence and significantly boost the overall power generation capacity of the module.
2. Developing a Low-Affinity Self-Cleaning Interface: Unlike the conventional “hydrophobic and oleophobic” approach, this project adopts a nanostructured design featuring “ultra-hydrophilicity + antistatic properties,” which effectively inhibits the electrostatic adhesion of airborne dust. Even in environments with little rainfall, this interface can achieve surface cleaning using minimal water, enabling “rainwater washes clean, and surfaces remain pristine even on dry days.” This significantly reduces the frequency of manual cleaning and lowers operational and maintenance costs.
3. Enhanced Environmental Durability: Designed to withstand harsh climatic conditions—including high temperatures, intense UV radiation, acid rain, and salt spray—this system features a highly dense interfacial coating that ensures long-term stable performance and meets industrial standards for outdoor use of more than 5 years.

02 Technical collaboration, seamlessly connecting the entire chain from the lab to the field.
This collaboration brings together JA Solar’s deep expertise in module integration and system validation with HysenMec’s innovative capabilities in the R&D of nano-coating materials and the implementation of coating processes. Together, the two companies will jointly develop a closed-loop technology spanning material design, process development, large-scale validation, and field application—positioning themselves as industry leaders in the photovoltaic sector. JA Solar has consistently been at the forefront of the industry in terms of high-efficiency module manufacturing and systematic solutions. Meanwhile, HysenMec boasts profound technical expertise and extensive practical experience across multiple industries in the field of high-performance functional coatings, including nano self-cleaning, light-transmission enhancement, and anti-corrosion coatings. Its products have been widely deployed in complex applications such as photovoltaics, wind power, high-speed railways, and military industries.

03 Establish standards, facilitate implementation, and jointly build a new industry ecosystem.
Taking this collaboration as a starting point, both parties will jointly promote the establishment of an application verification system and a standardization framework for photovoltaic functional coatings, addressing the current industry pain points of “lack of performance evaluation, absence of standardized interfaces, and no systematic definition.” This will help propel coating technology toward true standardization, industrialization, and widespread engineering applications.
In the future, this coating solution will not only be applicable to the manufacturing of new components but will also exhibit excellent compatibility with upgrades to existing components. It can be widely adapted to a variety of complex application scenarios, including ground-mounted power stations both domestically and internationally, distributed rooftop systems, mountainous site installations, and coastal tidal flats.

04 Looking to the future, focusing on long-term value
Under the “dual-carbon” vision, the core of competition in the photovoltaic industry has evolved from “single-point cost” to “system efficiency” and “full-lifecycle operation and maintenance capabilities.” Surface technology innovation—represented by functional coatings—will become one of the key pathways for enhancing the full-lifecycle value of PV modules.
Starting from this collaboration, JA Solar and Hysense will continue to accelerate joint efforts in scenario validation, system integration, and intelligent manufacturing, working together to drive the evolution of photovoltaic modules toward higher efficiency, lower maintenance requirements, and greater reliability.
Technology is leading the future of clean energy.
Turning more sunlight into clean electricity efficiently—that’s our shared mission.
