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.
It all starts with quartz, rich in silicon. The process heats up to extract pure silicon. This uses the floating zone technique for purity. Pure silicon is key for multi-crystalline silicon cells and mono-crystalline silicon cells, vital in solar energy today. The next step is turning pure silicon into silicon wafers.
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.
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.
Silicon wafer chemical texturing involves making the surface area bigger to increase light absorption. Fenice Energy uses special techniques to create tiny structures. These reduce light reflection and help capture more sunlight. Then, they thoroughly clean the wafer to remove any tiny residues. This ensures the solar cells work their best.
The silicon feedstock material is crystallized as either monocrystalline or multicrystalline ingots by various methods. These ingots are then cut into bricks with the footprint area of the silicon wafers.
