6 FAQs about [Photovoltaic panel silicon wafer cutting process]

How are silicon wafers cut?

The wafers are cut from silicon ingots using the wire sawing process (see Figure 1), which is an expensive step in the solar cell manufacturing process. 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].

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.
