The Rise of High Efficiency HJT Batteries: Market Trends and Future Prospects

Superior Efficiency and Technological Advantages

Exceptional Efficiency

HJT batteries have demonstrated an impressive average conversion efficiency of 24% to 26.5%. For example, LONGi Green Energy set a record of 26.30% efficiency in October 2021 and further improved it to 26.81% in 2022. Hua Sheng New Energy also achieved over 25% efficiency on its production lines. This high efficiency is due to the unique structure of HJT cells, which combines silicon and amorphous layers to capture more sunlight.

Advantages Over Conventional Technologies

HJT batteries offer several advantages over traditional technologies:

• Large Size Compatibility: HJT cells perform better with larger sizes compared to PERC (Passivated Emitter Rear Cell) batteries.
• Low Degradation: These batteries have high bifaciality and low degradation rates, ensuring consistent performance over time.
• Thin-Film Production: The production process is streamlined, reducing costs and simplifying manufacturing.

Market Performance and Expansion

Current Market Status

The HJT battery market is expanding rapidly. As of the end of 2021, the production capacity was approximately 3GW, with forecasts suggesting a potential increase to 5GW due to new contracts. However, despite these advances, HJT technology still holds a smaller market share compared to other technologies.
