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.

Is fixed abrasive diamond wire sawing a sustainable manufacturing alternative?

Concluding remarks In this paper, we reviewed fixed abrasive diamond wire sawing as a sustainable manufacturing alternative to loose abrasive slurry sawing of silicon wafers.

What is fixed abrasive diamond wire sawing (DWS)?

Recent industry trends indicate a shift from the loose abrasive slurry (LAS) sawing to fixed abrasive diamond wire sawing (DWS) process for slicing silicon wafers [2, 3]. DWS offers several advantages including smaller kerf loss, reduced wafer cost, and greater environmental friendliness when compared to the LAS process.

Will a shift from free abrasive/steel wire sawing to diamond sawing take place?

A shift from free-abrasive/steel wire sawing to fixed-abrasive diamond wire sawing is expected to take place in the PV cell manufacturing industry, with 2018 being the anticipated pivotal point for market dominance.

Can diamond wire sawing improve wafer production?

The results suggest that the diamond wire sawing process, with its potential for higher material removal rates and ductile mode cutting, could prove useful in producing stronger and higher quality wafers without sacrificing productivity.

What is the difference between slurry based silicon and diamond wire sawing?

In addition, the saw damage region of the silicon wafer is roughly half compared to slurry based wafers. The transition was quickest for monocrystalline silicon, but now also multicrystalline silicon has fully moved to diamond wire sawing.
