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.
While polysilicon and multisilicon are often used as synonyms, multicrystalline usually refers to crystals larger than one millimetre. Multicrystalline solar cells are the most common type of solar cells in the fast-growing PV market and consume most of the worldwide produced polysilicon.
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%.
Despite the fact, there is a wide gap between the conversion efficiencies of mc-Si solar cell and the single crystalline silicon (sc-Si) solar cell. Texturization technology might be a crucial factor to narrow the gap in conversion efficiency.
Microcrystalline silicon or nanocrystalline silicon consisting of crystallites of different orientations and sizes in the order of a few nanometers embedded in a residual amorphous matrix is being investigated for thin-film silicon solar cell technology.
Polycrystalline silicon, or multicrystalline silicon, also called polysilicon, poly-Si, or mc-Si, is a high purity, polycrystalline form of silicon, used as a raw material by the solar photovoltaic and electronics industry. Polysilicon is produced from metallurgical grade silicon by a chemical purification process, called the Siemens process.

Multicrystalline Silicon Cell
In a solar cell, the radiation is received from the sun, which is at a temperature of about 6000 K and a distance of about 150 × 10 6 km. A TPV device, however, receives radiation, in either the broad or narrow band, from a surface at a much lower temperature of about 1300–1800 K and a distance of only a few centimeters.

Polycrystalline Silicon Cells: production and characteristics
The standard size of poly-Si/ multi-Si cells is 6 inch (=15.24 cm). As compared to mono-Si cells, they have a grainy blueish coating appearance which is a result of the imperfect crystal structure of the cell. On average, the conversion efficiency of poly-Si/ mc-Si cells is between 14% and 16% with lab-records at currently over 21%.
