The newly developed six-inch n-type HJT solar cell "Hello 22" has maximum efficiency of 22.2% with excellent LID resistance. The power of 60-cell and 72-cell HJT modules can reach 325W and 390W with very low temperature coefficient of power, which can generate more electricity in high temperature environment. Considering the effects of LID and temperature coefficient, the 22.2% cell efficiency, the 325W and 390W module power are equivalent to 23.7% efficiency in p-type cell, 348W in p-type 60-cell module and 417W in p-type 72-cell module, respectively.
"Black 21", the mass-production six-inch p-type Mono PERC cell has been improved to maximum cell Efficiency of 21.4%, enabling maximum power of 315W and 375W in 60-cell and 72-cell modules. This product offers light induced degradation (LID) lower than that of p-type cells and low potential induced degradation (PID).
The new p-type PERC bifacial solar cell, named "Black 21-BiFi", had been developed with front-side maximum cell efficiency of 20.8%. The equivalent cell efficiency can reach 23.9% with 15% more power generated from rear side, which results in an equivalent power output of 335Wp and 405W for 60-cell and 72-cell modules.
