Characteristics of Sainty TOPCON Solar Cell

Higher Cell Efficiency

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.

Natural Symmertrical Bifacial Structure

Up to 95% bifaciality faciliates more sunlight to be captured and converted into power on the backside.

Superior Temperature Coefficient

The temperature coefficient of Sainty TOPCON cell is -0.26%/°C,which ensures more power output in high temperature environment.

SMBB Technology

Minimize the path of flowing current and lower resistance-related power losses,further improving cell efficiency.
