Super Heterojunction Cell Technology

A heterojunction cell combines all the advantages of crystalline and thin-film solar technologies in a single hybrid structure.
The Highest Efficiency

Use 210mm N-Type silicon wafer, the highest power up to 11W, the efficiency up to 25%.
Higher Bifacial Efficiency

The Bifacial efficiency rate is as high as 93-95%, the output of HJT cells per watt is about 3%-6% higher than that of bifacial PERC cells.
High power generation

30% higher front side power than conventional modules， up to 25% more power from backside
Higher efficiency at high temperature

The lowest temperature coefficientup to -0.26%/°C, at higher temperature, the output of HJT cell per W is about 0.6-3.9% higher than that of bifacial PERC cell.
Excellent weak light performance

Under the lower irradiation intensity, HJT cells have an average of 1 -2% more power per watt than PERC bifacial cells.
