The main advantage of monocrystalline silicon cells is the high efficiency that results from a high-purity and defect-free microstructure. Currently, the Cz method has evolved into a highly sophisticated technique, governed by multiple parameters. This complexity adds further challenges in understanding and enhancing the current methodology.
The typical lab efficiencies of monocrystalline cells are between 20% to 25%. In 2017, the Kaneka Corporation achieved the current highest efficiency record of 26.7%. Note: The efficiency of solar cells is different from the efficiency of solar modules. Solar cells will always be more efficient than their modules.
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. Back and front of a monocrystalline silicon cell.
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%.
Solar cells will always be more efficient than their modules. Even though monocrystalline solar cells have reached efficiency above 25% in labs, the efficiency of monocrystalline modules in the field has never crossed 23%. There are some advantages of monocrystalline solar cells over polycrystalline solar cells.
In the field of solar energy, monocrystalline silicon is also used to make photovoltaic cells due to its ability to absorb radiation. Monocrystalline silicon consists of silicon in which the crystal lattice of the entire solid is continuous. This crystalline structure does not break at its edges and is free of any grain boundaries.

Monocrystalline silicon is also used for high-performance photovoltaic (PV) devices. Since there are less stringent demands on structural imperfections compared to microelectronics applications, lower-quality solar-grade silicon (Sog-Si) is often used for solar cells.
