Technology Advancements of HJT Modules

Higher Bifaciality / 85%+ bifaciality

10%-20% back irradiation and higher bifaciality contribute to 2%-4% higher power generation per watt of HJT cells than bifacial PERC cells

Temperature Coefficient / -0.26%/℃

-0.26%/℃ heating coefficient of HJT cells, with 0.13%/℃ advancement
0.6~3.9% higher power generation per watt of HJT than bifacial PERC

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

HJT cells use N-type monosilicon wafer, PERC cells use P-type monosilicon wafer
weak light effect increases power generation per watt of HJT cells by 0.5-1% than bifacial PERC cells

LCOE / best LCOE

a cutting-edge and most prominent technology to best reduce LCOE

Low Degradation / low degradation rate

1% first year degradation of HJT cells, 0.375% for each successive year, significantly lower than 2% and 0.45% of bifacial PERC cells
1.9%-2.9% higher full life cycle power generation of HJT cells than bifacial PERC cells
