Furthermore, as TOPCon cell efficiencies continue to rise, research indicates that these modules are particularly vulnerable to ultraviolet-induced degradation (UVID).
To address these challenges, the industry has turned to an innovative solution: a specially engineered light conversion film that transforms harmful UV radiation into blue or red light—wavelengths that N-type cells respond to more efficiently. This film absorbs ultraviolet photons, excites conversion materials to a higher energy state, and then releases energy as blue light, mitigating UV-induced damage and enhancing overall module stability.
Overcoming Challenges in Light Conversion Technology
While light conversion films offer promise, existing materials face inherent challenges. UV excitation can trigger molecular interactions, leading to performance
decline due to energy loss from collisions, reduced conversion efficiency, and even cessation of luminescence. Other environmental factors—such as temperature fluctuations, pressure variations, and the presence of halide ions, heavy metals, or oxidizing compounds—further contribute to degradation, limiting long-term reliability.
Recognizing these limitations, HiUV has developed a next-generation UV light conversion film that achieves remarkable breakthroughs in stability and performance. According to HiUV’s technical experts, their proprietary UV conversion agent is cross-linked with the matrix resin to form a robust macromolecular network. Unlike conventional products, HiUV’s solution exhibits exceptional resistance to migration and exudation, ensuring high conversion efficiency even under extreme conditions such as intense UV exposure and high temperatures.
Unmatched Performance and Reliability
Rigorous testing underscores the superior performance of HiUV’s light conversion film:
Zero Migration: While competing products showed migration distances of 6–7 mm under 105°C conditions over 96 hours, HiUV’s film demonstrated no migration at all.
Exceptional UV Resistance: Under a UV lamp intensity of 240 W/m², HiUV’s film achieved a quantum efficiency of nearly 57%, highlighting its durability.
Enhanced Light Transmission: The film maintains an average transmittance of 17.69% in the 290–380nm range, retaining stability under damp heat and UV aging conditions.
Breaking Patent Barriers with Proprietary Innovation
A key differentiator for HiUV’s solution lies in its proprietary formulation, which circumvents existing international patent constraints. Unlike conventional conversion powders, HiUV’s UV light conversion agent is chemically grafted onto the molecular chains of the substrate resin during the lamination process—whether in EVA or POE-based encapsulants. This innovation not only ensures a more stable and efficient light conversion process but also provides robust legal protection, enabling HiUV’s market expansion without concerns over patent infringement.
A Game-Changer for the Solar Industry
The successful development of HiUV’s UV light conversion film is a testament to the company’s R&D leadership in photovoltaic materials. By offering PV module manufacturers a superior encapsulation solution, this breakthrough technology enhances the overall economics of solar power systems, reducing operational and maintenance costs while improving long-term efficiency.
As the world accelerates toward decarbonization and green energy transitions, HiUV remains committed to pioneering advancements in photovoltaic encapsulants. With continuous innovation in solar packaging technologies, HiUV is set to play a crucial role in driving cost reduction, efficiency improvements, and the broader adoption of sustainable energy solutions. By leading the charge in next-generation solar encapsulants, HiUV aims to shape the future of the photovoltaic industry and contribute to the global transition toward a low-carbon future.
