HJT 210-18BB
Product brief
Silicon Heterojunction (HJT) solar cells are manufactured by low temperature process with fewer manufacturing procedures, and are featuered high efficiency, high stability, no LID, no PID, low temperature coefficient, etc. It is also an excellent bifacial solar cell, with no color difference between front and back, a bifaciality of up to 90% and obvious advantages of back power generation. The finished product of Tongwei 210 series solar cell is half-cell, which can reduce the cutting cost of modules and avoid the power loss caused by module cutting.
