Sainty TOPCON solar cell was made of ultra-thin N-type silicon wafer which employs SMBB and μc-Si technology. The maximum efficiency has reached 25.61% in mass prodution, and there is a clear path of efficiency improvement with huge potential.
Max. Power of Single Piece: 6.77W
Max. Efficiency: 24.7%
Max. Power of Single Piece: 5.56W
Max. Efficiency: 25.2%
TOPCON cell uses α-Si thin-film as passivation materials to reduce the loss caused by the migration, which increases the open circuit voltage to 750mv.
Up to 95% bifaciality faciliates more sunlight to be captured and converted into power on the backside.
The temperature coefficient of Sainty TOPCON cell is -0.26%/°C,which ensures more power output in high temperature environment.
Minimize the path of flowing current and lower resistance-related power losses,further improving cell efficiency.
