Technology Advancements of HJT Modules

Higher Bifaciality / 90%+Bifaciality

HJT Bifaciality is about 10% higher compared to TOPCon. The overall Bifaciality advantage results in a power generation increase of 0.5% to 1.0%.

Temperature Coefficient / -0.24%/℃

TC: -0.24%/°C for HJT and -0.29%/°C for TOPCon, giving HJT an advantage of about 0.05%/°C. At 30°C to 35°C, HJT can achieve up to 2.5% more power generation than TOPCon.

NO PID NO LID / High Reliability

No LID caused by B-O effect, outstanding PID resistance by TCO film, to best guarantee long-period durability and yield.

Weak Light Performances / High Energy Yield

N-type substrates, with high minority carrier lifetimes, outperform conventional P-type silicon in low light, ensuring higher power output in low irradiation.

LCOE / Lower LCOE

A cutting-edge and most prominent technology to best reduce LCOE.

Low Degradation / Low Degradation Rate

HJT cells degrade 1% in the first year, with annual degradation <0.375% afterward, maintaining ≥88% power by year 30. HJT generates about 2% more power per watt compared to TOPCon.
