Standard Test Condition(STC): Irradiance 1000W/m², Cell Temperature 25ºC, AM1.5
HALF-CUTTECHNOLOGY
HIGHER POWER & MORE RELIABLE
Half- cut cell technology is to cut the cell into two seperate parts by mature infrared laser, hence halve the working current. The thermal loss on the ribbon will be remarkably reduced and the module' s power increases by 2%. The reliability of module is also enhlinced. The combination of half-cut cell technology and bifacial module can amplify the gain over the effect of current-reduction.
Monofacial or biftacial PERC cell module with half-cut technology has high power, the property of anti-PlD anti-LID (including LeTID) , low hot spot temperature excellent low irradiance performance and low power temperature coefficient.
