- Technology of HJT
- HJT Series
- PERC Series
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
