Technology & Innovation
Q.ANTUM Technology Deep Dive
At the heart of Hanwha’s competitive advantage lies their proprietary Q.ANTUM technology, which represents a significant evolution of PERC cell technology. Traditional PERC cells use a passivation layer on the rear surface to reflect unused photons back through the cell, increasing efficiency.
Q.ANTUM technology enhances this concept by incorporating an ultra-reflective coating that acts almost like a mirror, dramatically improving the cell’s ability to capture and convert sunlight. This reflective layer not only increases power output but also enhances performance in challenging conditions such as low light, high temperatures, and partial shading.
The technology delivers several key benefits:
- Enhanced Light Absorption: The reflective coating captures more photons, increasing overall efficiency
- Superior Low-Light Performance: Maintains 95% performance at 200 W/m² irradiance
- Improved Temperature Tolerance: Better performance retention at high temperatures
- Reduced Hot-Spot Formation: Enhanced thermal management prevents localized heating
Q.ANTUM DUO Enhancements
The Q.ANTUM DUO technology builds upon the foundation of Q.ANTUM with additional innovations designed to maximize energy yield and reliability. The most significant enhancement is the implementation of up to 12 busbars, compared to the 3-5 busbars found in conventional panels.
This 12-busbar design provides multiple pathways for electrical current, reducing resistance and increasing power output by approximately 1%. More importantly, it improves the panel’s resilience to micro-cracks and other forms of cell damage that can occur during transportation, installation, or thermal cycling.
The half-cell technology employed in Q.ANTUM DUO panels splits each solar cell in half, creating 132 or 108 half-cells instead of the traditional 60 or 72 full cells. This design reduces electrical resistance by 75% and significantly minimizes power losses from shading, as each half operates independently.
Anti-PID Protection
Potential Induced Degradation (PID) has historically been a significant concern in the solar industry, particularly in humid environments. PID occurs when stray electrical currents cause power output to decline over time, sometimes by as much as 30% within the first few years of operation.
Hanwha has implemented comprehensive anti-PID protection across their product lines, utilizing specialized encapsulants and cell treatments that prevent the formation of stray currents. Independent testing has confirmed that Hanwha panels maintain their original performance levels even after extended exposure to PID-inducing conditions.
Latest Innovations
In December 2024, Hanwha achieved a major breakthrough in solar technology by reaching 28.6% efficiency on an M10-sized perovskite-silicon tandem cell. This achievement, independently verified by the Fraunhofer Institute for Solar Energy Systems in Germany, represents the first time globally that a full-area industrial-sized cell has achieved such efficiency levels.
This tandem cell technology combines traditional silicon cells with perovskite materials, creating a multi-junction design that can capture a broader spectrum of sunlight. The technology promises to deliver 15% more power than conventional silicon modules and is expected to revolutionize solar energy efficiency in the coming years.
