How is a silicon wafer made?The process begins with silicon purification, where raw silicon is refined to remove impurities. The purified silicon is then melted and formed into ingots. Once the ingots are formed, they undergo slicing using diamond wire saws to create thin wafers, typically 150–200 micrometers thick.
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.
Can thin silicon wafers be made with increased mechanical strength?Hence, there is a critical need to address the problem of manufacturing thin silicon wafers with increased mechanical strength. 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.
Why is wafering important for solar cells?Another relevant field of research is the reduction of the wafer thickness in order to produce more wafers per kilogram silicon. Finally, the wafering process step, in combination with the material quality, defines the mechanical properties of the final solar cell, as the wafering process can damage the wafer’s surface.
Why do we need a silicon wafer substrate?With low damage depth in sliced wafers, less material usage due to reduced kerf-loss, and the use of less toxic water-based cutting fluids, DWS can produce large area, high- strength silicon wafer substrates to meet the demands of society for cleaner and renewable photovoltaic ener
