Rayzon Solar, a pioneering force in advanced solar technology solutions, has revolutionised the renewable energy market with its groundbreaking TOPCon modules. Offering not only unparalleled efficiency but also unparalleled durability and reliability, Rayzon Solar TOPCon modules represent a leap forward in solar technology. Through meticulous material selection and rigorous testing protocols, Rayzon Solar ensures that its TOPCon modules deliver exceptional performance in various environmental conditions, promising long-term stability and minimal degradation over time. By prioritising continuous improvement and collaboration with industry partners, Rayzon Solar cements its position as a key driver in the widespread adoption of TOPCon technology within the renewable energy sector.

Photovoltaic technology stands at the forefront of the renewable energy revolution, propelled by the relentless pursuit of higher solar cell efficiency. Rayzon Solar’s TOPCon modules have swiftly gained traction in the domestic and international markets, capturing nearly a quarter of production capacity in the initial phase of its launch. With the potential to push module efficiencies up to an impressive 28 percent, TOPCon technology is poised to lead the market in the coming years, building upon the foundation laid by previous advancements such as Mono PERC technology.

The innovative Tunnel Oxide Passivated (TOPCon) solar cells placed by Rayzon Solar employ a unique cell structure featuring an insulating silicon dioxide layer within the bulk semiconductor. Overcoming classical mechanics limitations, this thin insulating layer facilitates electron flow through quantum tunnelling, thereby enhancing overall cell efficiency. N-type TOPCon solar cells offer distinct advantages over their P-type counterparts, such as resistance to common degradation issues like LID and LeTID, lower temperature coefficients and higher bifaciality factors. Despite being a relatively new technology, TOPCon modules have already demonstrated their potential through rigorous testing, proving their reliability and longevity in the field.

Rayzon Solar commitment to quality is evident in the extensive testing conducted on its TOPCon modules. Third-party laboratories have confirmed the reliability of its dual glass TOPCon panels, showcasing minimal power degradation even after prolonged exposure to damp heat tests. However, challenges remain, particularly with transparent back sheet variants experiencing significant degradation, primarily attributed to filling factor and short circuit current issues. To address concerns regarding front-side contact corrosion, experts recommend using polyolefin elastomer encapsulants, ensuring long-term performance and stability.

Ultraviolet-induced degradation (UVID) threatens solar cell longevity, particularly for advanced cell architectures like TOPCON. Rayzon Solar continuously tests the UV degradation of its TOPCON modules in its in-house Reliability Test Laboratory to ensure product quality and reliability. Similarly, potential-induced degradation (PID) presents challenges, especially in hot and humid climates. The company’s TOPCon modules are designed to withstand PID effects, with rapid recovery mechanisms in place to counteract any degradation.

In conclusion, Rayzon Solar TOPCon modules represent a paradigm shift in solar technology, offering unmatched efficiency, durability and reliability. With a steadfast commitment to innovation and quality, Rayzon Solar continues to lead the charge towards a sustainable energy future, driving the widespread adoption of renewable energy solutions worldwide.
