6 FAQs about [Photovoltaic solar wafer process flow]

How do you make a wafer for a solar cell?

Wafer preparation Once the monocrystalline or multicrystalline ingots are fabricated, they must be shaped and sawed into wafers for subsequent solar cell fabrication. This process implies a material loss. First, the head and tail of the ingot are discarded, and the ingot is given a square shape by cutting off the edges.

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.

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.

How are PV solar cells made?

The manufacturing process of PV solar cells necessitates specialized equipment, each contributing significantly to the final product’s quality and efficiency: Silicon Ingot and Wafer Manufacturing Tools: These transform raw silicon into crystalline ingots and then slice them into thin wafers, forming the substrate of the solar cells.

Why do solar cells need wafer etching?

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. This damage has to be etched not only to increase the mechanical stability but also to obtain good cell efficiencies.

Can silicon wafers be used to make solar cells?

Once the silicon wafers are fabricated, they can be used to manufacture solar cells. As you learned in Chapter 3, a solar cell is fundamentally a device optimized to absorb light, generate carriers (electrons and holes), and selectively extract them through its terminals in the form of a current flowing through a load.
