Hanwha Solutions Q CELLS Division is set to simultaneously launch a new series of solar modules, the Q.TRON G2, in Korea and Europe in February. Following its pioneering mass production of the globally dominant Passivated Emitter Rear Cell (PERC) cells and modules, Hanwha Q CELLS now becomes the first Korean company to release Tunnel Oxide Passivated Contact (TOPCon) cells and modules.
The Q.TRON utilizes Hanwha Q CELLS’ proprietary TOPCon cell manufacturing technology, Q.ANTUM NEO, to achieve approximately 1%p higher energy efficiency than existing PERC cells. The Q.ANTUM NEO technology is a unique approach by Hanwha Q CELLS that maximizes power output efficiency by forming a thin oxide layer to regulate the movement of charges in N-type wafers, which are advantageous for maximizing energy efficiency. The maximum output of the Q.TRON series, utilizing these high-efficiency cells, is 630 Wp (watt-peak), which is about 25 W higher than existing modules of the same area.
The Q.TRON series not only excels in initial performance but also in long-term reliability and durability, surpassing existing and competitive products. Utilizing high-quality N-type wafers, the Q.TRON series has improved upon the efficiency degradation seen in existing products using P-type wafers and has enhanced product lifespan.
Moreover, while the average annual degradation rate of other companies’ N-type TOPCon modules stands at around 0.4%, the Q.TRON series boasts the industry’s lowest degradation rate of just 0.33% annually, promising higher electricity generation and profits over the long term. Additionally, the Q.TRON is designed to withstand various weather conditions, including high temperatures, heavy snow, hail, strong winds, and significant temperature fluctuations, ensuring stable use over a long period.
Hanwha Q CELLS also applies conditions up to three times stricter than the International Electrotechnical Commission quality inspection standards for rigorous quality control. In 2022, it became the first in the industry to obtain the new solar module quality inspection certification from the globally renowned testing organization TÜV Rheinland, earning recognition for its thorough quality management.
