Faller gill, some probes are set on probe row, it is characterised in that：The probe mining makes of transparent material, the quantity of probe row
It is consistent with the vertical thin grid line quantity without main grid solar cell, beaten in the position of correspondence solar cell piece pad on every probe row
Hole, installation probe, the diameter 2.0-3mm of probe, the spring pressure of probe tip is 1.2-2N.
Further, the material of probe row is transparent PMMA materials, the diameter 2.5mm of probe, probe tip
Spring pressure 1.5N.
The present invention in the main gate line in many main grid solar cells or the vertical thin grid line without main grid solar cell by setting
Pad is put, and probe row is designed to transparent material, the number of pads one in the quantity and solar cell of the upper probe of probe row
Cause, number of pads is 6-10, and so, probe and main grid are effectively contacted when on the one hand making test, on the one hand reduce probe band
The shadow occlusion for coming, so as to ensure the accurate of test result；Meanwhile, probe row without excessive hole also under causing the life-span
Drop, the life-span of probe row is consistent with the quantity that average probe is arranged.
