Sample loading system

With the box-to-box sample loading system a stack of up to 100 solar cells (125 mm or 156 mm) can be measured without further action by the operator. Sensitive solar cell surfaces may be protected with paper interleaves. Two cameras are used to check the integrity of the solar cell, the orientation of the gridlines, the number of busbars, and whether an interleaving paper needs to be removed. A third camera captures labels written onto the backsides of the solar cells. Also part of the sample loading system is a weight scale with an accuracy of 0.02 g.
