Similar to the HE-WS-02 sorting unit, the HE-WS-03 offers the possibility for sorting PV wafers according to predefined quality criteria. The extension of the storage capacities for wafers at the sorting units allows further cost optimization arises for PV manufacturers.
3 x 4 boxes are installed on one side of the sorting unit. These so-called quad-boxes allow to store up to three quality levels of wafers before the boxes have to be changed by hand. Like this, the fourfold amount of wafers can be processed before the exchange of boxes has to be done by hand. This means that up to 15 boxes can be filled before operator action is needed again.
