4.1.1 Silicon Wafer Cells4.1.1.1 Monocrystalline Silicon. Large (up to 300 mm diameter), cylindrical ingots of extremely pure, single-crystal silicon are grown from molten silicon. The entire ingot is doped, usually p-type with boron, during the melt phase and is sawn into circular wafers less than 0.5 mm thick, from which solar cells are made.

Conventional monocrystalline silicon cells can operate efficiently at lower concentrations (1–100 sun) without needing active cooling mechanisms. Low concentration systems generally feature wider acceptance angles, and in some cases do not need to track the sun, reducing their cost.
A monocrystalline solar cell is fabricated using single crystals of silicon by a procedure named as Czochralski progress. Its efficiency of the monocrystalline lies between 15% and 20%. It is cylindrical in shape made up of silicon ingots.
Monocrystalline silicon cells can absorb most photons within 20 μm of the incident surface. However, limitations in the ingot sawing process mean that the commercial wafer thickness is generally around 200 μm. This type of silicon has a recorded single cell laboratory efficiency of 26.7%.
Angel Antonio Bayod-Rújula, in Solar Hydrogen Production, 2019 Monocrystalline silicon cells are the cells we usually refer to as silicon cells. As the name implies, the entire volume of the cell is a single crystal of silicon. It is the type of cells whose commercial use is more widespread nowadays (Fig. 8.18). Fig. 8.18.
Multicrystalline cells are produced using numerous grains of monocrystalline silicon. In the manufacturing process, molten multicrystalline silicon is cast into ingots, which are subsequently cut into very thin wafers and assembled into complete cells.
Monocrystalline silicon PV cells are produced with the Czochralski method, generated from single silicon crystals. Their manufacturing process is quite expensive since they require a specific processing period. Their energy pay-back time is around 3–4 years (Ghosh, 2020). Their efficiency varies between 16 and 24 %.
