In crystalline silicon solar cell production typically five to seven process steps are applied in a linear sequence to the bare wafer, before the processed wafer is cut and used to build-up photovoltaic modules. Whereas in microchip fabrication there are up to 400 process steps before the array of microchips on the silicon wafer is finished and can be cut, packaged,

The effective heat transfer between the cutting fluid and the silicon wafer surface can be only ensured when the phase change temperature of the core material matches that in the cutting zone. Based on the research of Xu [ 27 ]and our preliminary experimental results, the average temperature of the diamond wire saw cutting area is from 26 °C to 45 °C.
During the wafer producing process, approximately 35%–40% of crystalline silicon ingots are wasted in the form of silicon powder and become the so-called silicon powder waste (SPW), since the thickness of the silicon wafers is nearly equal to the diameter of cutting wire (Yang et al., 2015). The produced SPW through the LAS technology has complex

It is a development trend in solar silicon wafer cutting. Thin wire cutting reduces the kerf between silicon wafers to less than 50 μm. Therefore, it is extremely difficult to supply cutting fluid to the cutting area. And this affects cutting performance. This paper proposes the use of the capillary effect produced by ultrasonic

According to a comprehensive report by Kings Research, the Wafer Cutting Fluids Market is estimated to garner USD 2,447.6 million in revenue by 2030, expanding at a compound annual growth rate (CAGR) of 4.95% from 2023 to 2030. These specialized fluids can make a big difference in the quality and efficiency of your wafer-cutting process, but choosing the right one
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 energy.
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.
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].
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.
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.
The degree of amorphization affects the subsequent saw-damage removal and texture etching of as-sawn wafers during solar cell production. Budnitzki and Kuna compared the depth of transformed zone from multiple studies and found it to be in the range of 1-2 µm, as shown in Figure 13.
