6 FAQs about [Diamond wire cutting photovoltaic panels is harmful]

Can diamond wire sawing be used for photovoltaic silicon wafers?

This paper reviews recent research on diamond wire sawing of photovoltaic silicon wafers and compares it with the loose abrasive wire sawing process from a standpoint of sustainable manufacturing.

What damage does diamond wire sawing cause?

Damages caused by diamond wire sawing are responsible to have an asymmetry in fracture strength, a lower strength in parallel bending and a higher strength in perpendicular bending to the saw marks.

Is diamond wire sawing better than slurry based sawing?

In addition, diamond wire sawing is expected to result in lower total thickness variation (TTV) of the wafer and in reduced metal contamination of the Si surface [1,2]. Reports also indicate that saw damage depths are lower with diamond wire sawing than with slurry-based sawing [1,3].

Does diamond wire sawing reduce breakage force?

“There has been a significant gain in momentum for diamond wire sawing.” However, diamond wire saws have been shown to decrease the breakage force for c-Si wafers by as much as a half, because of the formation of elongated cracks on the silicon surface during sawing .
