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.
Si wafers constitute 52% of the total price of solar cells. The silicon wafer manufacturing process has evolved from slurry-based wafering to diamond wire sawing. The process of cutting with a diamond wire saw is discussed in detail, including its advantages over earlier sawing processes.
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 key components in solar PV manufacturing include silicon wafers, solar cells, PV modules, and solar panels. Silicon is the primary material used, which is processed into wafers, then assembled into solar cells and connected to form solar modules.
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 manufacturing typically starts with float glass coated with a transparent conductive layer, onto which the photovoltaic absorber material is deposited in a process called close-spaced sublimation. Laser scribing is used to pattern cell strips and to form an interconnect pathway between adjacent cells.
