Hanwha Q Cells to unveil Q.TRON G2 solar module

Hanwha Q Cells Co., a solar power unit of South Korean conglomerate Hanwha Group, announced on Monday that it will unveil its new solar module series the Q.TRON G2, in South Korea and Europe this month.

The Q.TRON series incorporates Hanwha Q Cells' proprietary high-efficiency tunnel oxide passivated contact (TOPCon) cell manufacturing technology Q.ANTUM NEO, which increases power generation efficiency by about 1% compared to conventional passivated emitter rear contact (PERC) cells by creating a reflective layer on the back of the cell.

The Q.ANTUM NEO technology enables the Q.TRON series to increase its maximum output to 630 Watts-peak (Wp), which is about 25 Watts (W) higher than existing modules of the same area.

Hanwha Q Cells has previously pioneered the mass production of PERC cells and modules and is now the first Korean company to launch a TOPCon module, the Q.TRON.

The Q.TRON also boasts its long-term reliability and durability under various weather conditions, surpassing existing and competitor products, according to Hanwha.

By reducing the efficiency degradation rate compared to existing products that use P-type wafers, the lifespan of the product is enhanced.

The efficiency degradation rate of Q.TRON is at the industry's lowest level, at 0.33% annually, which is lower than the average of 0.4% for other companies' N-type TOPCon modules, allowing for higher power generation and profits over the long term.
