Multicrystalline silicon cells. Multicrystalline cells, also known as polycrystalline cells, are produced using numerous grains of monocrystalline silicon. In the manufacturing process, molten polycrystalline silicon is cast into ingots, which are subsequently cut into very thin wafers and assembled into complete cells.

Malek Kamal Hussien Rabaia, ... Abdul Ghani Olabi, in Renewable Energy - Volume 1 : Solar, Wind, and Hydropower, 2023 Multicrystalline silicon (mc-Si) solar cells have a bandgap of 1.11 eV while its efficiency on a laboratory scale goes from 15% to 18%.
Presently, most multicystalline silicon for solar cells is grown using a process where the growth is seeded to produce smaller grains and referred to as "high performance multi" 1 Slab of multicrystalline silicon after growth. The slab is further cut up into bricks and then the bricks are sliced into wafers.
Multicrystalline silicon (mc-Si) is silicon material with multiple grains of crystals with different orientation and shape.
Crystalline silicon cells are further categorized as either monocrystalline silicon cells that offer high efficiencies (13–19%) but are more difficult to manufacture or polycrystalline (also called multicrystalline) silicon cells that have lower efficiencies (9–14%) but are less expensive and easier to manufacture.
