In field applications, small area shadings can cause the temperature of those parts extremely high. This phenomena is called hot
spot. The long duration of hot spot could bring irreversible degradation of modules.

Production & QC
Half-Cut Technology
Half-Cut Technology
Half cut cell technology is to cut the cell into two separate 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
enhanced. The combination of half-cut cell technology module can amplify the gain over the effect of current-reduction..

Lower Hot Spot Temperature
Lower Operating Temperature
Half-cut cells have half of the working current, thereby the thermal loss is remarkably reduced. Operating temperature
correspondingly decreases, and the reliability of module is improved as well as power gain.
correspondingly decreases, and the reliability of module is improved as well as power gain.
Lower Shading Loss
Because of the unique parallel connection design, half-cell modules still have 50% power output under the circumstance of array
shading in sunrise or sunset when portrait installation. In addition, half-cut technology can improve the output of bifacial
module under non-uniform incident illumination on the backside.
