Technology

What is a half cell?

Half-cell technology is a technique of laser cutting a standard size cell (156 mm x 156 mm) equally into two cells (156 x 78 mm), which are cut and connected together. The cells of the entire module are then divided into two groups, each containing 60 half-cells connected in series, and the cells form a complete 120-cell module, thus reducing the current through each main grid to 1/2 of the original, and reducing internal losses to 1/4 of the whole cell, thus increasing the module power.

1.Higher Yield Due to Better Shading Response

Half Cell Module comprises two separated and identical solalr cell arrays, which means the ordinary strings of cells are cut into halves, and these shorter strings compose which has separated current paths. When a module is shaded, only one side shaded array's current will be impacted, while the other array will still be functionally producing power. Under this circumstance, when a module is shaded, the affected working areas of Blade will be 50% less.

By cutting solar cell into halves, the internal power loss will be lower and hot spot effect will also be reduced.

2.Less Mismatch Loss

Instead of 6 internal strings of cells, half cell module has 2*6 shorter ones. This design effectively deals with the mismatch happened between cells caused by shadow, out of sync performance degradation, etc.
