6 FAQs about [Photovoltaic bracket sawing machine processing method]

How to advance the multi-wire sawing process?

Another approach for advancing the multi-wire sawing process is the omission of slurry, which is only possible if wires with fixed abrasives are used. For this purpose, diamond wire with small diamond particles attached to the wire is mainly used.

What is multi-wire sawing?

Multi-wire sawing uses a brass-coating steel wire. The tensile strength of the wire is approximately 4000N/mm2 and the standard thickness is between 120 and 140μm for photovoltaic applications. In experimental research wires as thin as 100μm have being tested . Fig. 5 shows a 120μm wire before (left) and after the cutting process (right).

What are the parameters of multi-wire sawing?

The following sections discuss some important parameters of the cutting process in more detail. Multi-wire sawing uses a brass-coating steel wire. The tensile strength of the wire is approximately 4000N/mm2 and the standard thickness is between 120 and 140μm for photovoltaic applications.

What are the machine parameters for the cutting process?

The machine parameters for the cutting process depend on many factors such as wire thickness, machine type, wafer thickness, brick length and grain size, among others. The machine parameters that must be chosen are the table and wire speed, the tension of the wire and the flow and temperature of the slurry.

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 .

Can wire sawing produce crystalline wafers for solar cells?

Wire sawing will remain the dominant method of producing crystalline wafers for solar cells, at least for the near future. Recent research efforts have kept their focus on reducing the wafer thickness and kerf, with both approaches aiming to produce the same amount of solar cells with less silicon material usage.
