Once the rod has been sliced, the circular silicon wafers (also known as slices or substates) are cut again into rectangles or hexagons. Two types of silicon wafers for solar cells: (a) 156-mm monocrystalline solar wafer and cell; (b) 156-mm multicrystalline solar wafer and cell; and (c) 280-W solar cell module (from multicrystalline wafers)
A wafer is a thin, flat disk or rectangle of base semiconductor material. Wafers are 180μm to 350μm thick and are made from p-type silicon. Crystalline silicon cell wafers are formed in three primary types: monocrystalline, polycrystalline, and ribbon silicon.
Both polycrystalline and monocrystalline solar panels use wafer-based silicon solar cells. The only alternatives to wafer-based solar cells that are commercially available are low-efficiency thin-film cells. Silicon wafer-based solar cells produce far more electricity from available sunlight than thin-film solar cells.
Thanks to constant innovation, falling prices, and improvements in efficiency, silicon wafer-based solar cells are powering the urgent transition away from producing electricity by burning fossil fuels. And will do for a long time to come. What Are Thin Film Solar Cells?
The manufacture of crystalline silicon modules involves fabricating silicon wafers, transforming the wafers into cells, and assembling cells into modules. A wafer is a thin, flat disk or rectangle of base semiconductor material. Wafers are 180μm to 350μm thick and are made from p-type silicon.
A polycrystalline wafer is a silicon wafer made from a cast silicon ingot containing many silicon crystals (see figure 2). To form an ingot, molten silicon is poured into a crucible and cooled steadily and cautiously for several hours. Several silicon crystals form and grow as the molten material solidifies during cooling.
