Aiko Solar Raises the Bar in Solar Efficiency
Aiko Solar, a prominent player in the solar manufacturing sector, has achieved a remarkable 24.8% efficiency with its latest Comet 3N solar modules. This achievement, certified by TÜV Nord in Germany, marks a significant milestone in commercial solar module production, underscoring the company’s commitment to advancing renewable energy technology.
Breakthrough Technology Behind the Achievement
The efficiency of Aiko’s Comet 3N modules is made possible through the company’s innovative All-Back-Contact (ABC) technology. This proprietary design moves all electrical contacts to the rear of the solar cells, enhancing the light-absorbing surface area by approximately 1.1%. Additionally, it utilizes overlapping cells to incorporate 0.5% more active silicon, resulting in higher energy conversion rates.
Enhanced Performance Metrics
The peak cell efficiency for these modules reaches an impressive 25.05%, demonstrating Aiko’s ability to push the boundaries of solar technology. The company has previously set records with efficiencies of 24.4% in June 2025 and a lab-tested efficiency of 25.2% announced at Intersolar 2024. These advancements not only highlight Aiko’s leadership in the field but also reflect the growing capabilities of back-contact technologies in surpassing traditional solar cell designs.
Real-World Applications and Market Impact
Aiko’s Comet 3N modules are already in use across various megawatt-scale projects in regions such as China, Southeast Asia, and Europe. Notably, these modules are designed for commercial and industrial (C&I) applications, proving their reliability and efficiency in diverse environments. By adopting these high-performance modules, stakeholders can expect:
- Reduced balance-of-system costs.
- Increased energy yield and overall system performance.
- Enhanced sustainability through lower silver usage in manufacturing.
Looking Ahead: The Future of Solar Technology
The rapid advancements in solar module efficiencies, particularly with Aiko’s back-contact technologies, indicate a shift in the industry landscape. Current forecasts suggest that such technologies will dominate the market by 2027-2028, as they offer superior temperature coefficients and aesthetic benefits compared to conventional options like TOPCon and PERC.
Strategic Deployments and Global Influence
Aiko is not only focused on efficiency but also on expanding its global footprint. The company has secured substantial supply agreements, including a 1 GW supply agreement in Australia set for 2026-2028, which will further bolster its presence in key markets. Moreover, their deployment of 18 ground-mounted systems in Japan showcases the versatility and reliability of their modules in real-world conditions.
Conclusion: A Call to Action for Battery Enthusiasts
The achievement of 24.8% efficiency is not just a technical milestone; it represents a significant leap towards more sustainable energy solutions. As battery enthusiasts, understanding the implications of such advancements in solar technology can help you make informed decisions about integrating solar power into energy storage systems. Keep an eye on Aiko as they continue to innovate and lead the charge towards a more sustainable future.
